Mac Server app: Network users have proper permissions but Network Groups are unable to make changes to files

From https://discussions.apple.com/thread/3288643

  "So here is what I did wrong. I changed the default group that was already set for the share point. It is however IMPORTANT to ADD a new group or user if you want to keep the inheritance. As far as I know the default permissions are only responsible for posix and not for ACL. Be sure to add this new group on top of the others and then propagate the permissions."

There are two things in play here, POSIX style permissions (*nix based) and NFSv4 ACLs (Access Control Lists) used on your server.

You set them to AFP after ongoing issues using SMB.  Things seem to get hairy when using AFP and Apple changed up SMB a lot after breaking ties with SAMBA and implementing their own, albeit lesser version of SMB (you Mac geeks out there, correct me if I'm wrong - I want to know...)

From an article on TechRepublic I found this great explanation:

  Most UNIX systems use the standard POSIX (Portable Operating System Interface) permissions when managing access to files. Standard POSIX permissions are independent of which file system they are used on (provided the system supports them), and anyone familiar with Linux or UNIX will be familiar with them as they are the standard way to set very basic access control on files and directories.

  Essentially, you can define the owner of a file or directory, the group that owns it, and "other" (everyone who is not the owning user or a member of the owning group). You can further define whether or not each of these has read, write, or execute permission to the file or directory. With a file, these permissions mean that the user can read the file, write to it, change or delete it, or execute it as a program. For directories, these permissions mean that the user can read the contents of a directory (but not necessarily the contents of the files in the directory), can write to the directory (create and delete files), or execute (allows the user to traverse that directory tree in order to access files or subdirectories, although it does not on its own allow permission to see the contents of the directory).

  Most operating systems also support some form of Access Control Lists (or ACLs). Often times this is also dependent upon which filesystem is in use, or which implementation can be used on which file system (the two primary ACL types are POSIX.1e ACLs and NFSv4 ACLs). Mac OS X is no different and, as of OS X 10.4, it has supported NFSv4 ACLs when used with the HFS+ file system. Using these ACLs on OS X are quite simple; you may even be using them without knowing it.

  ACLs are made up of ACEs (Access Control Entries) and each ACL can contain more than one ACE. ACLs provide a lot more flexibility and fine-grained control over permissions of files and directories than standard POSIX permissions. For instance, some of the capabilities that ACLs provide for files include read, write, execute, and append permissions (append only allows you to add to an existing file, not change existing contents or remove it). Some capabilities for directories include listing entries, searching entries, adding a file, adding a sub-directory, or deleting contents. Another nice feature of ACLs is called "inheritance," where you can set an inheritance permission so that a directory's file contents can inherit one set of ACLs, while directories inherit another set.

  As you can see, ACLs are very powerful. For instance, if you had a directory that contained developer manuals, you might make the directory writable to developers and read-only to sales people. You might also want to give interns access to some of the files, but you don't want to make them a part of the developer or sales group because those two groups have access to too many other files. In this scenario, you might make the directory owned by one particular user, or the root (administrator) user, and group-owned by the "developers" group, with the files and directories writable by both the owner and group. You would then use ACLs to apply read-only permissions to certain files for the "sales" group, and could also use ACLs to apply read-only access to the explicit users that are interns (as opposed to creating a new group for interns). With standard POSIX permissions, this would not be easily possible.

  If you have used the Finder Get Info command on a file or directory, most likely you have noticed the Sharing & Permissions pane at the bottom. By default, it shows the standard POSIX permissions entries:

  These permissions, on the command line, would equate to an ownership of "vdanen:staff" and mode 0750 (or 0640 if this were a file). This can be seen on the command line as:

  drwxr-xr-x  2 vdanen  staff     68 Mar 11 22:30 New

  To add ACLs to this directory, you can either use the chown and chmod commands, or the Finder. Using chown/chmod gives a lot more flexibility as the Finder limits you quite a bit and makes certain assumptions for you. For instance, to give access to this directory to members of the admin group as Read Only, you would click the + button in the Sharing & Permissions pane, select the user or group, and then set the appropriate privilege:

  Now the members of the admin group have read-only access to this folder. Not very difficult to set in the Finder, is it? We can also observe the ACLs on the command line, using the -le switch to the ls command:

  % /bin/ls -le
  total 288
  drwxr-xr-x+ 2 vdanen  staff     68 Mar 11 22:30 New
   0: group:admin allow list,search,readattr,readextattr,readsecurity

  The Finder gave more permissions than just the "list" or "search" permissions; it also allows the admin group to read extended attributes and ACLs.

  To accomplish the same on the command line, you would use:

  % mkdir New2
  % /bin/chmod +a "admin allow read,readattr,readextattr,readsecurity" New2
  % /bin/ls -le
  total 288
  drwxr-xr-x+ 2 vdanen  staff     68 Mar 11 23:06 New2
   0: group:admin allow list,readattr,readextattr,readsecurity
  % /bin/chmod +a "admin allow search" New2
  % /bin/ls -le
  total 288
  drwxr-xr-x+ 2 vdanen  staff     68 Mar 11 23:06 New2
   0: group:admin allow list,search,readattr,readextattr,readsecurity

  As you can see, the initial chmod command missed an ACL; it's easy enough to add a new entry later. And if you need to remove one, that is easy too:

  % /bin/chmod -a "admin allow search" New2

  The admin group now no longer has search permissions on this directory. You’ll note that in each case, I am specifying an explicit path to the ls and chmod commands. This is because I have Fink installed, and the GNU tools that are installed through Fink do not understand OS X ACLs, and these commands will not work with them (the default PATH on the system puts /sw/bin before /bin/, so when I type "ls", it is "/sw/bin/ls" that is being executed, rather than "/bin/ls").

  Mac OS X Server (and, presumably, Lion as well) has a more sophisticated GUI front-end to manipulating ACLs than the Finder, but for most basic tasks, the Finder will suffice. It does not handle inheritance, however, which is a shame. It does allow you to apply the permissions set on a directory to files and directories within it by using the "Apply to enclosed items..." menu entry from the gear pull-down menu, which arguably accomplishes something similar; however, if you change the directory permissions you need to re-apply them, and also if you added new folders or files, etc.

  The chmod manpage (”man chmod”) gives a very good explanation of ACLs and how to apply them. ACEs in an ACL do observe order, so you can use chown to specify where a specific ACE needs to be positioned within the ACL, and of course you can get a lot more specific than you could with the Finder.

  ACLs on OS X work very similarly to ACLs on other POSIX systems, including Linux. The permissions may differ somewhat, as does the mechanism for implementing and managing them, but the benefits are identical. This ACL support in OS X is also compatible with certain versions of Windows and Windows Server.

And if that isn't enough, here is some really good in-depth information on sharing, including sharing and viewing the shares from Terminal.


How do I change the default sound for Reminders in El Capitan?

You were on the right lines, but the wrong location…

System sounds are in /System/Library/Sounds/ it's only user sounds in ~/Library/Sounds
Replace the Basso.aiff in there with your custom version [bearing in mind this will replace Basso in any other system alert that uses it too]

It will be the same for Calendar alerts - except there you can define which system sound to use, so if you did need a separate custom sound in there you could apply the same logic to one of the other system sounds in the Library folder.

Note that in El Capitan you would first have to disable System Integrity Protection before you can modify the Sounds folder…

  Reboot your Mac into Recovery Mode by restarting your computer and holding down Command+R until the Apple logo appears on your screen.
  Click Utilities > Terminal.
  In the Terminal window, type in csrutil disable and press Enter.
  Restart your Mac.

  Revert the same way using csrutil enable


Where are environment variables specified when .profile, .bash_login, .bash_profile cannot be found?

It sounds like you are using bash.

bash first runs /etc/profile. /etc/profile (on Mac OS X 10.6.7) runs path_helper(8) which is where your default paths get set. After that it runs /etc/bashrc which doesn't do much. Once the default configuration is set, it moves on to the user login scripts.

bash looks in your home directory for .bash_profile, .bash_login, and .profile in that order. bash will run the first of these that it finds and stop looking.


What should I do if my headphones don't go into my iPhone 4s

If none of the headphones you try (you should try different sets) can physically fit into the port, then there is probably something lodged down in the port. Shine a light down it and see if you can find anything. If you have repeatedly tried to dislodge whatever may be there but seem unable to get it out, go to an Apple store and see what they have to say about it.


What is spotlight indexing and should I turn it off?

Leave it on.

You use an OS that heavily depends on this, you need to allow it to index.

Yes, it keeps track of where all your documents & data are. After any major OS update it will re-index from scratch; the rest of the time it will just periodically tick away in the background, interfering with nothing and helping a lot of the system.

SSDs are more resilient than people give them credit for. Yes, the more you use it the faster it will wear out, but a bit of file indexing is going to perhaps shorten its life by 20 minutes or so, overall ;-)


How can I move Contacts from Exchange to the From My Mac groups?

Unfortunately, iPhone Groups are not meant to be edited from within the iPhone Contacts app. You can try copy iPhone contacts from one group to the next using a third-party program designed to access your iPhone Contacts app from a PC.


Is the Macbook 12 inch's USB-C charger interchangeable with other USB-C chargers or devices?

This answer is indented to be canonical answer for similar questions and applies to all devices that utilize USB (Type A or C) chargers and conform to the USB Power Delivery  specification (version 2.x through 3.x).

  If there is only the MacBook 12 inch USB-C charger nearby, can it be used to charge other USB-C devices, such as any Android phones that also use USB-C? (will it "too powerful" and damage other devices?)

Yes, it can be used and you will not cause any damage.

USB-C conforms to the USB 3.1 specification.  Part of that specification is the Power Delivery spec.  This means that the device and charger will negotiate the power that is delivered.

As to whether a charger is too powerful or not, you can always use a charger greater than or equal to the maximum power draw of the device.  This applies to all chargers (USB, barrel connector, etc.), not just those that conform to the USB 3.x specification.

In other words, if your Apple USB-C charger is capable of delivering 87W of power, but you only need 10W for your phone, you can charge your phone no problem.

However, your 10W phone charger should not be used to charge your 87W MacBook.  Why?

If it's USB 3.x (USB Type C), it will negotiate power.  Since it technically doesn't have enough, it will either charge slowly or not at all
If it's USB 2.x (USB Type A) or a regular type charger, it will either not charge or have the possibility of damaging the charger because the draw of the device will exceed the charger's ability.

(MagSafe power adapters have a chip built into it prevent using an under-powered charger).

  Vice versa, if there is a Quick Charge 2.0 or 3.0 USB-C charger from other devices nearby, can it be used to charge the Macbook 12 inch?

Possibly.  The power delivery spec allows for power negotiation.  If there is sufficient power, it will charge, albeit slowly.  It may charge, but not power your device.  It may do nothing (it couldn't agree on a negotiated power delivery so it stopped delivering power).  If it's a poor quality charger (and does not conform to USB 3.0+ spec) it may overheat.

This is why you always use chargers greater than or equal to your device load.


What is the upper limit of Spaces in Lion?

16 spaces is still the maximum. (Tested on 10.7)


Internal keyboard randomly stops working (after upgrade to Catalina) - any way to reset it?

This appears to be a Karabiner bug (at least in my case).


How to turn off retina resolution in iMac 5k?

The retina display causes any somewhat graphic intensive apps to be laggy. It's a major design flaw. You can fix this by right clicking on any app and clicking "get info". Then click on "open in low resolution".

You'll be surprised to see how fast apps run now. It will look not as clear, however. The retina sucks. My 2011 macbook ran everything better because it didn't have a retina display.


I am assuming that you just want to copy paste files/folders from your main (Windows) machine to the Mac or vice versa.

You can do this other way around (using Mac) pretty easily. In your Mac go to the Finder and in the Go menu in the menu bar you see "Connect to Server…". Use this option and enter the IP address of your Windows machine. Then login with your Windows ID and password.

Now unless you unmount this connection you will see your Windows machine as an external drive in your left side of your Finder windows and you will always be connected. If you want to close the connection, you can simply click on the eject button on the Windows drive which should be on your left pane in the Finder window (which shows Macintosh hard drive, Applications etc.). Note that this requires your Windows machine to have file sharing on.

You could also install an ssh/scp program on Windows (such as that included in Cygwin) and use that to transfer files (turn on Remote Login in the Mac's Sharing preference pane).


What is the purpose of Mark as a Company on Mac Contacts?

Two reasons:

Firstly, it's so the contact displays the company name when you receive a call instead of a personal name.

Secondly, it also sorts it in alphabetical order into your contacts by company name and not by a personal name. This is especially useful as contacts are sorted alphabetically by surname and not by first name, ie. Tim Cook is listed under "C" in your contacts but if you were to have "Apple Computer" you would want this sorted in the A's and not the C's.


Is there a hidden way to fast charge an iPhone/iPad from a newer USB-C Mac?

No, a USB-C to lightning cable that is Apple certified will charge iOS devices at the fullest capacity the new MacBook Pro will provide to a USB and lightning connector.

That same cable will fast charge from USB-C PD compatible chargers like the Apple ones.

iOS doesn’t present as thunderbolt so you don’t get that amount of power over lightning connector.

The technical details are available to any organization that participates in the MFI program - https://en.wikipedia.org/wiki/MFi_Program and the signaling between devices to decide to fast charge is somewhat sophisticated and possibly has an encryption / identity key (I haven't seen the specifications so that part is speculation).

There’s nothing hidden. Apple could decide to increase the charge since they control all the drivers and power management and SMC and lightning specifications. They just chose the 5w you are seeing.


How to press `^|` in Visual Studio on macOS?

iPhone 8 Plus (iOS 11.4) is frozen on emergency SOS screen

iOS 11.4 is currently under development and you have either a developer or public beta installed on your device. Beta version of iOS are not guaranteed to work without issues.

Try restarting the device. If the issue persists, and it is hindering your workflow, it is recommended you restore the device to current public release of iOS, i.e. iOS 11.3.1.

You can share any observations and issue with Apple, via the Feedback app installed on your device.


Black hole all IP addresses except for 192.168.1.1

Mac OS X like other BSD systems uses ipfw instead of iptables. Read the man page for full reference.

One way to would be to deny all TCP "establish connection" packets except those directed to gitserver, leaving all other traffic untouched:

ipfw add allow tcp from me to gitserver setup
ipfw add allow tcp from me to me setup # may not be needed
ipfw add deny tcp from any to any setup

The rules will be lost on reboot, so they must be set on every boot (e.g. from /etc/rc.common or crontab's @reboot).

If that seems too complicated, get a third party firewall. Little Snitch is a good one, but it costs another $30 :)


There are a few methods to accomplish this:

If you have another Mac accessible, boot the dying Mac into Target Disk Mode. Plug it into the other Mac via Thunderbolt or Firewire. You should see your dying Mac show up as an external hard drive. Drag and drop what is needed.
Get an external hard drive at least the size of your Mac's internal drive. Plug it in and boot into Recovery Mode. Open Disk Utility. You should see the external drive and boot volume. Use Disk Utility to Restore one volume to the other. This will destroy any existing data on the external hard drive.
If you can't reformat an external hard drive but have a bit of space available to move the select files you need, you can boot into Recovery Mode and use Terminal to move the files over that you need. Use the cp UNIX command to do this. For example, to move all of your Documents to an external hard drive named "External" you would use the following command:

cp -r "/Volumes/Macintosh HD/Users/joe/Documents/" "/Volumes/External/"


Are the apps opened in CarPlay still running after disconnecting phone from the car?

You don't ever need to to force quit apps when you're done with them.
Evidence provided by Apple themselves a few years ago

If you don't tell a SatNav you've finished your journey*, then it will keep actively navigating.

Otherwise, just unplug your phone & off you go.

*Some of them insist on continuing to navigate to some pre-determined spot 50m from where you actually wanted, so until you pass through its destination point it will still keep on trying.

Incidentally, apps can be told from settings not to be allowed to use your location &/or track anything whilst not active, & Google apps can also be told from your Google account not to track you.


How can I recover lost secure notes in Keychain?

Stupid, silly me.

The left column has a pane for Keychains and a pane for categories.

The keychain pane has

login
local items
System
System Roots.

The Category pane has

All Items
Passwords
Secure Notes
My Certificates
Keys
Certificates.

These two are in essence multipied together.  That is, ANY of the keychains can have any of the categories.

In my wanderings I was somehow clicked into local items instead of login.  I had not created a local items secure note, so of course secure notes was blank.

Embarrassing as it is, I'm leaving this up for future klutzes.


OS X El Capitan how to stop mail opening (many) popup windows for calendar notifications?

This is a copy/paste from my own answer at https://apple.stackexchange.com/a/174732/85275 with slight modifications

Changes per OS...
Since Sierra, Mail is in V4
Since El Capitan, Mail is in V3
All the rest will be the same.
If your machine has been upgraded through these OSes, you may have all 3 folders.

Try clearing the saved state, rebuilding & reindexing the database...

Clear Saved State

Switch to Finder,  Cmd ⌘   N  for a new window, then  Cmd ⌘   Shift ⇧   G  for Go To...
copy/paste ~/Library/Saved Application State/com.apple.mail.savedState then  Enter ⌅
This is an alias to the real location, so Right-click & Show Original
Delete the entire com.apple.mail.savedState folder.

Rebuild; Re-index

Source: How to fix Apple Mail by rebuilding and reindexing the Mailbox

  Step 1: Rebuild
  Rebuilding a Mailbox in Mail sounds daunting but it really isn't.

  Launch Mail, select one of your mailboxes and click on the Mailbox menu. At the bottom of the pane choose the Rebuild option. If you have a large mailbox, you can expect the process to take a few hours.
  You must repeat this step for each one of your Mailboxes.
  While the process takes place, you may experience system performance lag, as it can consume a lot of system resources and memory.

  Another caveat, if you use IMAP or Exchange with any of the accounts, the process will redownload every message from the server, so you'll use a lot of bandwidth.

  Now that you've completed these steps, work with Mail a little longer. If you are still having issues, or Mail fails to launch, you should try a manual reindex.

  Step 2: Re-index

  Manual reindexing of Mail messages is the only way to go if the  application has become so unresponsive it barely works at all, search is not functioning correctly or the app won't launch.

  Mail will automatically attempt to reindex your messages if it detects problems with the mailboxes, but sometimes a manual reindex is the best option. If you are still having problems with Mail after following step one, try manual reindexing.

  Quit Mail if it’s open.
  To get to your home Library folder, hold down the Option key, then in the Finder choose Go > Library.
  In ~/Library/Mail/V2/MailData, delete any file that begins with “Envelope Index,” such as Envelope Index or Envelope Index-shm. (Before you actually delete the files, it makes sense to copy them to a folder on your desktop.)
  Launch Mail and the app will build new Envelope Index files -- this can take a long time if there are numerous messages to go through.
  If everything seems to be working correctly, you can now delete the copies of the "Envelope Index" files from your desktop.

  In most cases, these two tips should solve most Mail problems


Issue with receiving Apple ID account change notification emails

I don't think anyone is messing with you.
- Have you checked spam folders?
- Check your email's trash can.

There is always the chance that the email failed to send from apple's side or failed to reach you in transit. But if you tried again and everything is working fine like before, then I don't think someone is messing with you.


How do I change the order in which login items execute under OS X 10.8.2?

I use TinkerTool (free) to handle that little job.

TextEdit shows dialogs about not having permission to open any files

I ended up replacing TextEdit's code signature with an ad-hoc signature:

sudo codesign -f -s - /Applications/TextEdit.app/

It disables sandboxing, so for example the preference files are in ~/Library/Preferences/ instead of the sandbox container.

Edit: The dialogs returned after I reinstalled OS X, and now I'm getting errors like this for codesign -f -s -:

$ sudo codesign -f -s - /Applications/TextEdit.app/
/Applications/TextEdit.app/: replacing existing signature
/Applications/TextEdit.app/: object file format unrecognized, invalid, or unsuitable

I'm using https://github.com/jjgod/TextEditPlus for now. It's based on a version of TextEdit that came with 10.7, but it works with 10.8.2.


Backup Photos using Google Photo Desktop Uploader

I wasn't sure if this was possible, but I'm please to report that it is, and I'm going to use it myself. The trick is to understand that Photos Library.photoslibrary is a Package File that Google Photos Backup doesn't know how to see inside. However, Finder does. So, right click on Photos Library.photoslibrary (normally inside your Pictures folder) and select Show Package Contents. All of your pictures are inside of Masters, organized by date added (however note that any edits you made in Apple Photos are not included; these are the original images).

Now, run Google Photos Backup and click Add to select the folder. Drag the Masters folder into the File Dialog:

Now click Choose, and you've succeeded in getting the Google Photos Backup to look inside the Apple Photo package. You may want to unclick the other watched folders, since Apple Photo should already be importing all images.

I just figured this out, so I'll update if I find any downsides. Since Google Photos is completely free for the High Quality images (as opposed to Original resolution), it will be interesting to compare the two services.


Error during install of lzip on MacOS 10.11.6

You're logged in as an ordinary user which do not have write permissions for system folders like /usr/local/bin/.

Normally you'll run the last command like this:

sudo make install

This means that the "make install" command should be executed with administrative privileges - and thus having write permissions for system folders.

Alternatively you can rerun the configure command giving it a bindir that is inside your own home directory. Then you can install the binary to there, but you'll then have to specify full path to the binary every time you want to run it.


Try deleting it with Terminal:

rm -rf /Volumes/diskname/path/to/folder

This command will remove (forcefully and recursively) the path given. Be careful when entering the path to ensure you delete the correct folder, as there's no protection against deleting everything. Note that Terminal will show no progress whilst this is being carried out — the prompt will return when it's complete.


My Macbook air won't go to sleep when I close the lid

Your output from pmset -g assertions matches mine perfectly - nothing there would prevent a quick sleep. To dig into this deeper, I like to open a command line windows/tabs and run two commands in different shells:

pmset -g pslog
iostat 5

You can change the 5 counter - I usually use iostat 60 or more to track long term CPU and IO trends, but sleep wake happens pretty quickly when things are running correctly with "out of the box" power settings and a fresh / new OS installation.

Here you can see the timing on the lid down and lid up:

2017-09-10 10:47:24 -0500 IORegisterForSystemPower: ...Sleeping...
2017-09-10 11:42:32 -0500 com.apple.system.powersources

 -InternalBattery-0 (id=4128867)    100%; discharging; 3:42 remaining present: true

Here you can see the jump in the iostat 5 where the CPU was idle entering sleep (the 4.00    1  0.00   1  1 98 being low IO, and 98 % idle CPU) for the first two lines go together. Most of the values jump up the three "intervals" when I woke the lid from sleep and the CPU kicked in gear to run all the tasks needed to wake from sleep and resume apps / catch up on periodic activities missed while sleeping)

How to copy files in /Applications/* using Terminal?

Applications that come preinstalled with macOS are protected by SIP.  The Calendar App, being preinstalled falls under this category.  Firefox, for example, wouldn't.

So, anything in

/Applications/Calendar/..... is protected
/Applications/3rdPartyApp/.... is not

  System Integrity Protection restricts the root user account and limits the actions that the root user can perform on protected parts of the Mac operating system.


Mails message contents not 'wrapping' (i.e. running off edge of box)

Looks like an HTML email has some CSS settings off the mark. Sender's fault. There is a little you can do. Hit altcmdU and see it in an even worse format but at least the text lines would break way before the width ends.

The shortcut corresponds to View menu → Message → Raw Source.


How to install an homebrew formula without updating homebrew itself?

According to this github issue and to the man page, the environment variable HOMEBREW_NO_AUTO_UPDATE can be set to 1.
HOMEBREW_NO_AUTO_UPDATE=1 brew install <formula>

This will stop the homebrew update for this command. If you want to prevent auto update for your shell session, use:
export HOMEBREW_NO_AUTO_UPDATE=1

to set it permanently, add it to your ~/.bash_profile. Note that changing this permanently is discouraged by the developers.


MacBook Pro (16-inch, 2019) doesn't recognize 2nd monitor

Not sure if this would work for you, but my MacBook Pro was not detecting a Dell 2nd screen while my buddy's older MacBook Pro did.
All I had to do was reseat the cable on the monitors side - the pins were a bit loose and I just tightened them all the screws all the way.


Administratively, how can you purchase multiple licenses from the Mac App Store?

Administratively, it might be easiest to use the gift feature to purchase all the 10 apps at once and file your expense reports. You are then free to use that account to redeem one copy - or pass off one (or more) of the redemption codes to whatever deploy accounts you use.

Currently, the iOS app store has more volume purchase options:

App Store Volume Purchase Program for Education
App Store Volume Purchase Program for Business

I would join one of these if you can and inquire if/when it would extend to the Mac App Store for OS X. (Nothing speaks louder than action).

In the mean time, you can use gifting to separate the payment from the redemption and hand out the redemption codes as needed to the actual accounts you use to deploy the apps. I haven't had any issues with one account on 15 macs to ease the administrative burden. Do make sure to buy enough copies before adding new macs to keep things within the terms of the license. My reading (and I'm not a lawyer) is a person can install their apps on macs they control and own with no limit (not 5 or 10) and businesses/organizations are to buy one license per machine. I don't see a technical or moral reason to actually redeem each copy (especially if you secure / never further distribute those redemption codes).

I personally can't wait until a unified volume plan arrives for the Mac App store - discount or not, having it centrally managed and downloading a spreadsheet to track things is so useful as we're more constrained with time and expertise than the cost of the software at present.


Roll back from OS X Mavericks ( or any newer OS) to Mountain Lion

Since the question does not mention backups, I guess there aren't any.  What you can try in this case, is to make a time machine backup (e.g. on an external USB Harddrive) of the current Mavericks partition.

Then do a clean install (as suggested by jaume) and then use the migration assistant getting your data back from the Maverick backup into Mountain Lion.


How to fix  missing icons and labels in System Preferences -> Spotlight?

Assuming your drive passes hardware verification, you might want to rebuild your spotlight index.

First though, repair permissions as much as possible.

Rebuilding the spotlight index is straightforward but time consuming. You will see that it is indexing as the spotlight magnifying glass icon will have a dot in the center of the glass.

This is how to reindex your drive:

Launch System Preferences from the  Apple menu
Click on “Spotlight” and then click on the “Privacy” tab
Drag Macintosh HD (and other drives if necessary) into this window

Click “OK” when asked to confirm
Now select the drive(s) you just added and click the “-” minus button to remove it from the list (weird right). Note: if an item is left under the “Privacy” list, it will exclude from Spotlight indexing completely.

Spotlight will immediately begin to reindex the drive(s) you added and then removed from the Privacy list. Note: How long it takes to reindex the drive varies, ranging from 30 minutes to several hours, depending on the speed of the drive and it’s contents. At any point, you can pull down the Spotlight menu and check the progress:

The Mac will probably feel sluggish during reindexing as the mdworker and mds processes run and consume a lot of CPU and cause a lot of disk activity.
After all this, if the problem still occurs, here are some other techniques:

Alternative #1: Kill SystemUIServer

Launch ‘Activity Monitor’ (located in /Applications/Utilities/).

Locate the process ‘SystemUIServer’, highlight it, and click the red button “Quit Process”.

Within a few seconds the menubar will rebuild itself and often Spotlight will magically work.

Alternative #2: Rebuild the Spotlight Index manually

Launch ‘Terminal’ (located in /Applications/Utilities/)
At the command prompt, type this exactly (copy and paste):
sudo mdutil -E /

You will be asked for your password, provide it, as this command requires administrator privileges to run.

You will receive a confirmation message saying that index will be rebuilt.

Wait until index is finished rebuilding, this can take a while depending on the size of your hard drive, amount of files, etc.

Alternative #3: Change Desktop Resolution

This is a strange fix but it works sometimes.

Open “System Preferences” via the Apple Menu

Click ‘Displays’ and select a resolution smaller than what you are currently using, 640×480 seems to always work

Select your native resolution again, changing your screen resolution back to normal

The Spotlight search tray will magically become available again

Alternative #4: Clear caches and preferences

Clear caches and preferences relating to Spotlight, this is best done using a tool like OnyX, MainMenu and/or Cocktail.

Alternative #5: Clean the Font caches

Sometimes, this is adequate to repair a screwy Spotlight, but it won’t hurt to clear them all

Hope this helps (I got this information from experience, but a lot of the text is lifted from OSXDaily.)


How to run AppleScript (.scpt) as LaucnDaemon by root

Assuming your launchd job is correctly set-up, you may be reaching a limitation of AppleScript.

AppleScript Requires a GUI (Aqua Session)

If your AppleScript is launched using launchd as a user root process, it will not have a graphical user interface associated. The majority of AppleScript requires a graphic user interface to work consistently. Depending on the version of OS X, it may work, but it is not designed to.

Processes on OS X can not trivially cross between user sessions.

Do Shell Script

A more robust approach is to separate out the functionality needing higher privileges into a shell script such as bash, perl, ruby, or python.

Your AppleScript can then call that script using AppleScript's do shell script:

do shell script "command" user name "me" password "mypassword" with administrator privileges

If you need to avoid embedding a username and password, this is possible but beyond the scope of this question.


How can I see app reviews in itunesconnect from all store fronts?

I think it just mean you have 6 people rated your app but no one has written any reviews. But I don't think it is possible to see reviews from all regions.

It could also be possible that review takes time to show up. source

  Your review might need to be approved before it's published, so it might not appear immediately.

What is PSNormalizer / normalizerd process

I believe I now know what was causing this. I attempted to print to a Kyocera photocopier that doubles as a fax machine. This process seems to have been going around and around, attempting and re-attempting to create documents in a suitable format for faxing. I found the (unprinted) documents in a lingering unseen print queue. Having removed the documents, the uncontrolled disk writing has ceased.


The search bar sticks to the top of the mail items and "bounces" with them when scrolled past the top.


How can I force pinch-to-zoom on some websites?

Ugh, this is so annoying -- it is the height of designer/developer arrogance (in my opinion -- and I'm a developer myself). The other answer's code did not work for me, but after much experimenting I got this to work (iPad 3/iOS 5):

javascript:document.querySelector('meta[name=viewport]').setAttribute('content','width=device-width,initial-scale=1.0,maximum-scale=10.0,user-scalable=1');

Use the same method as the other answer says to add it (create a bookmark for any page, then edit the bookmark and replace its URL with the above code).


MacBook Pro Retina 15'' Late 2013 Stoppped Charging

It is possible the logic board needs to be replaced.

I would try resetting your SMC (manages the power in the laptop):

Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

How do I reset link between iPhone and iTunes on a Mac?

I have had similar problems with music and photos. Often, if you look at the files on the iPhone list via iTunes, they will be listed, but grayed out with a 'sync next time' icon next to them.

Somehow, these get in a halfway state, where the iPhone thinks they are queued for sync, but then they never do.

The only way I have found that resolves this issue is to first backup the phone on iTunes, then restore it, which wipes the phone, reinstalls iOS, then reloads your backup. When I do this, the sync list is cleared, and the files will sync as normal.

Good luck!


I called Mac support and they had me delete some files from my computers' cache and then reboot in safe mode and open the document. I then deleted my trash can and rebooted in regular mode and the problem was fixed.


How can I listen to a whole album on iTunes?

Assuming you are using a Mac with a newer system and the latest iTunes do the following:

Go to Album view

Now move the cursor to an album which will "enable" a play button in the lower right corner. Hit the play button to play all songs of this album:

If you click once more on the album you will see the content of the album:

To see the content of another album click on it - this won't interrupt the playback of the first album:

To play the second album either

move the cursor over the second album and click on the then enabled play button
move the cursor over the cover of the "expanded" album and click on the then visible bigger blue-on-white play button

move the cursor over one of the titles of the "expanded" album and click on the then visible small blue play button


How do I configure dynamic DNS when my router does not support it?

ddclient is what I use on my Linux boxes. Works really well.

You can find instructions details here: http://sourceforge.net/apps/trac/ddclient

I think all you would need to do to get ddclient to run is to a @reboot line to your crontab and you’re set.

crontab -e

then add this line:

@reboot /usr/sbin/ddclient -daemon 300 -syslog


iTunes asking for password for wrong iTunes account

Try signing out of iTunes on your iPhone and signing in as your Apple ID. After you login as the right account, delete all the apps you have downloaded and redownload them.


Installing more than one battery pack in Macbook?

From a battery controller logic standpoint, I am fairly confident that is not possible, in the sense that the result will not be a stable configuration. The reason is simply that there is no mechanism to handle such a scenario on a logic level.

My understanding is that a MacBook battery has some simple logic and communicates the charge level and other battery internal states to the charging controller on the mac logic board. If you parallel-wire two batteries together, the logic on those two batteries will generate cross-talk when the logic board controller tries to talk to the battery.

The logic board sends an enquiry, which will go to both batteries, and the two batteries will answer back at the same time, possibly with different answers. That will not go down well in the logic board controller.

So I think the only way this would be possible is if you could connect the two batteries to a hypothetical 3rd party battery controller board, which in turn would be connected to the MacBook logic board, mediating the communication between the logic board and the batteries.


How to install LP_solve solver on Yosemite?

The easiest way is doing it using homebrew. You just need to type the following couple of commands in a terminal window:

brew tap brewsci/science
brew install lp_solve

If you don't have homebrew installed, just type the following to install before the previous commands:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"


How do I select part of an audio track in GarageBand 10.3.2?

Edit: Sorry. Just noticed you asked for GarageBand and not Logic. Updated answer for GarageBand which has fewer split options.

You have to split the track. Once you've split it, you'll be able to copy the region onto the clipboard and paste into another project.

You can split at the playhead position using Edit > Split Regions at Playhead or use the Cmd-T keyboard shortcut.

Just put the playhead at 23.25, split. Move it to 25.00 and split again. Then you'll have a region you can select and copy onto the clipboard.


Why is the Apple logo upside down when the lid is open on the older Apple notebooks?

A former Apple employee, Joe Moreno has a blog post explaining why:

  "We were told by the Apple design group, which takes human interface
  issues very seriously, that they had studied the placement of the logo
  and discovered a problem. If the Apple logo was placed such that it
  was right side up when the lid was opened then it ended up being
  upside down when the lid was closed, from the point of view of the
  user."

So when closed, it appeared right-side up from the point of view of the user. But when opened, it appeared upside down from the perspective of on-lookers. Joe Moreno states that "Opening a laptop from the wrong end is a self-correcting problem that only lasts for a few seconds. However, viewing the upside logo is a problem that lasts indefinitely."

All of these decisions of course went through Steve Jobs. With the release of the current Macbook product lines, Jobs reversed his decision and had the logo appear right-side up from on-looker's perspective.

Insert key on keyboard for Macbook Air Mountain Lion OS

An external keyboard or on screen keyboard with numpad is required.

See page 4 here > http://na.sage.com/sage-300-erp/sage-300-erp-online/~/media/site/sage-300-erp/assets/online/Sage-300-ERP-Online-Mac-Resource-Guide.pdf

Mac keyboards lack the Insert key which is used in Sage 300 ERP for adding new lines to lists.

So instead, if using a Mac, on a keyboard with a number pad, with Numlock OFF, the “0” button will act as the Insert key.


Emulating associative arrays in AppleScript

Although AppleScript does have associative arrays, they are called "records".  I tried using AppleScript records to give you a solution. In the code below, I was unable to use a string as a key.  I did manage to use something that resembles a file name, an identifier, but this isn't really working.  It's an idea of how to use an associate array in AppleScript though:

set theAssociativeArray to {|file name 3.jpg|:{width:400}, |file name 1.jpg|:{width:222}}

-- looking things up by key in an AppleScript record, which is really a dictionary, is fast
try
    get |file name3.jpg| of theAssociativeArray
    say "file name 3 is on list"
on error
    say "file name 3 is not on list"
end try
try
    get |file name 1.jpg| of theAssociativeArray
    say "file name 1 is on list"
on error
    say "file name 1 is not on list"
end try

I saw that in your example code, you defined lists of records.  What I tried to do is to define records of records.

I think that the main thing to keep in mind about the strengths and weaknesses of AppleScript is that is a language designed for Interapplication Communication (IAC), revolving a round the "tell command" to tell different apps to get data, set data, and to control the apps by telling them commands.

Here is a link to an answer that I believe is relevant to an AppleScript solution for you:

Finding the Intersection of Two Lists

The ultimate solution using AppleScript would be to use AppleScriptObjC which would allow you to use Objective-C classes such as NSDictionary that are very much like associative arrays.


Are you referring to the self-discipline-enforcing mechanism like this one?   That is: something that notices that you are spending a lot of time doing various things that you don't want yourself to do (too much web browsing in general, or perhaps too much Facebook in particular, or too much email...?).

If that is the case, then it is difficult to imagine how something like that could be written using the official SDK that Apple provides, because you would need to modify Safari, or block IP addresses, prevent other apps from launching, or some such thing.  These are not things that the official SDK allows a software developer to do.

Perhaps there is something in the world of jail-broken devices, but I can't speak to that point since I have never ventured into that territory.


Can I charge my MacBook Pro from an older iMac?

There's no other way of charging a 2012 MacBook Pro than through the MagSafe power port. If that has stopped functioning, you cannot charge the laptop as usual.
Your options are primarily:

getting the MagSafe power port repaired
taking out the battery and charging it externally and put it back
take out the hard drive or SSD (depending on model) and transfer data externally

To recover the files I would prefer the last option, taking out the drive. It is an ordinary SATA interface, so you should be able to buy a cheap USB-to-SATA interface at most computer stores, that would enable you to transfer the data to another computer.


Pending Transaction doesn't disappear out of Apple Wallet

To remove the duplicate transaction you need to refresh your Apple Wallet transactions by removing your Apple Card and re-adding it.
Go to Apple Wallet, select your Apple Card, click the 3 dots on the top right, scroll to the bottom, and click on Remove This Card.
You can then add your card back by clicking the + on the top right of the main Apple Wallet screen. Once it's added back, your transactions should be refreshed and the pending transaction should be gone.


Missing Notification Center Widgets & Share Extensions

Apple has a knowledge base article for this bug occasionally affecting macOS Yosemite, El Capitan, and now Sierra. This happens most often after installing an OS update.

To reregister all Notification Center widgets and Share Extensions, start a Terminal session, and enter the following:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed

(Triple-click the above line and press ⌘ cmdc to copy, then ⌘ cmdv inside Terminal.)


Is it possible to determine the model of an iOS device by its MAC address?

No - it's not a good way to get that data.

I would have a look at some of the many MDM software packages to get your population data so you can plan. JAMF has a great reputation in that space for low cost of entry and high performing software.

Also - you could make a quick little app that simply reported in some basic stats. Your users will be clamoring for potential apps and those willing to run that app will feed you with the data needed.

You will find that making the app forces you to restrict many of the new features and in reality - you'll have to actively work to get 3.x support in a project you start today using the current Xcode 4. 4.0 will be easy and only the new 5.0 features will get you into having to test the levels and have two sets of code for different generations of device.

Your development will drive what devices people use and not the other way around. It's almost always cheaper to just upgrade devices than pay developers to keep the older code tested and running.

There are lots of great charts out showing what some devs are seeing for how fast people upgrade to the latest iOS versions.


iPhone playing songs NOT on any of my playlists

Playlists are just organized subsets of your music library, so you might not have the song on the playlist, but still have it in the collection.  Even if you just have a single playlist, that doesn't mean that every song on your phone is in it. iTunes will default to the first song alphabetically if you tell it to "Play" when it doesn't have a playlist loaded (i.e. the first time after turning on the phone).

At least under iOS 6 (I haven't upgraded yet), you can see all songs by tapping the "Songs" tab at the bottom of the Music app.  If his music is there, you can delete it from there.  If it isn't, then there's something else going on.


Actually it went away and came back again

We sent it to apple care in another state and found it to be corrupted logic board, they repaired and its as good as it can be


I've managed to refresh it by loading ./apple-touch-icon-precomposed.png, but I only had apple-touch-icon.png in my main folder and had deleted the outdated precomposed one, so I believe you have to go to the original address that was stored in iOS Safari's cache.

It could be any of the following addresses, which are recommended by Apple Documentation on Web Applications:

apple-touch-icon-precomposed.png
apple-touch-icon.png
touch-icon-ipad-retina.png
touch-icon-ipad.png
touch-icon-iphone.png

And don't forget to compress your PNG to save bandwidth!


For every song the you import into iTunes, a copy will be made in your iTunes Media folder. If you want to delete a song from iTunes, I would suggest you do it by right clicking on the song and hit delete. Then it will let you decide if you want to remove the referente to that song in iTunes or move the file (the one in iTunes Media, not your music folder) to trash.

If you need to open a different library or reload one, make sure iTunes is closed and click on the icon while holding the option button on your keyboard and then navigate to your iTunes Media folder


Can similar apps be uploaded on Apple Store?

The problem is you're trying to upload an app that already is very similar to existing apps.

Yes, you're probably getting rejected because both apps are under the same dev account.  You could try 'reviewer roulette' and see if you submit under another dev account that another reviewer will approve it. That's unlikely based on how the App Store has been cracking-down on apps such as yours (that are very similar to other apps).

My recommendation is not to do this.  Add the items from the second app into the first app.


MacBook Pro 15 2017 Battery Condition: Replace Now

Your MacBook Pro needs to go in for service.

There are two telling signs that there is a (serious) hardware issue.

The power button can't turn it on, but it will turn it off
You have 0A being measured at the battery

There could be an issue with the SMC chip itself (it's nothing more than a power controller chip) or the circuitry supporting the SMC (charging power is 12-16V while the SMC communicates and "controls" with 3V).  Without putting hands on the actual unit, it would be impossible to tell.

In other words, the SMC could be failing to charge the battery or the circuitry that charges the battery could have failed.

As far as the battery goes, it's entirely possible it's fine, it's just that it's not being measured properly (0A) given the symptoms.  However, it's not unheard of that a brand new battery with hardly any charge cycles goes bad and no longer holds a charge - it happens.

Again, without putting hands on, it would be next to impossible to tell and given the age (3 months), the best thing to do is send it in (mail in  if possible).

It's a hardware issue and there's no getting around this. Firmware and a 3rd party boot loader will not address an issue concerning a chip that is technically supposed to be functional when the power is "off".

However, if you are so inclined to, open the back and disconnect the battery for 30 seconds.  That should reset the SMC.


Setting up bash_profile but alias not found?

I copy and pasted code again from Safari into TextEdit and it worked.

 alias bp='open ~/.bash_profile'

I deleted my profile, re-started Terminal, and re-did it by hand, and it broke again. It only works when I paste the code from Safari. So weird. No idea why this is.

If anyone has any idea, let me know because i'm so confused.


Macbook Pro renders font differently then other screen

It looks different because your Macbook and the Dell does not get the same resolution. Your Macbook should display 1280*800 or 2560 x 1600 or other, and the Dell displays 1900*1200. The ratio is not the same, it has to be stretched.


Press the refresh icon to the far right of the print job.  This should bring up the dialogue for your credentials, supply these and then make sure to check the box to save them to your keychain and then it will pass this through for any subsequent print jobs.


Is there a way to get Terminal on Lion to start up cleanly (without the buffered history)?

You can change terminal only with this one command to write a new preference for that specific app.

defaults write com.apple.terminal NSQuitAlwaysKeepsWindows -bool false

This is general, so of course, substitute safari or quicktimeplayerX or whatever in the com.apple.terminal portion of the command as needed. This setting switches the default save behavior upon quitting that one app. You'll find many of the other apps that work well with this setting by searching on NSQuitAlwaysKeepsWindows.

Of course, you should issue this defaults command after closing all windows and then quitting the application to ensure the settings are read the next time Terminal starts.


As the Mac mini has no battery, would it fail or just suspend if the power is cut?

As with any computer which does not have a battery you will lose everything not saved to disk if you unplug the computer from the power  supply. If you use a Mini in an unstable environment, adding a UPS might reduce the risk of data loss.


Can apps use different Twitter accounts on iOS?

Developers access your Twitter accounts through the Accounts framework.

When an app requests access to your accounts, it uses the requestAccessToAccountsWithType:withCompletionHandler: method. (The only supported account type is currently ACAccountTypeIdentifierTwitter.) This grants access to all accounts of that type.

Therefore, unfortunately, apps can't request access to only a single account — you have to give access to all of your Twitter accounts.


According to @IconDaemon there is no key combination to do this. A possible workaround is to select a word or phrase, or line that you want to move and while holding the mouse button down you can drag the selection elsewhere in the file.


macOS Sierra, Multiple problems with iBooks syncing to iTunes 12

I would download Calibre to edit the metadata before adding the file saved by calibre to Books.
Also, I've found that unchecking ibooks in system preferences>icloud>icloud drive on my mac fixed the issue with itunes, and I only really read books on my iPad/iPhone, and having Books turned on under icloud on those devices' settings doesn't seem to mess anything up so this works for me.


What is the best method of locking a kids ipad to a particular app?

The Guided Access method is the one that is usually suitable for home usage. It is, as you describe, easy to break out of if you want.

If you want to protect against reboot breaking out of Guided Access, then "Single App Mode" is the way to go. In contrary to what you write, it is not necessary to have an MDM system for that to work.

All you need to do is download the free app "Apple Configurator 2" from the App Store on a Mac. Connect the iPad with a cable, and select the iPad in Apple Configurator 2.

If this is the first time you use Apple Configurator 2 with the iPad, you'll  want to click the "Prepare" button in the top bar. You'll want to choose to prepare with "Manual Configuration". Do not add to device enrollment program or add MDM. Choose also that you want to "Supervise devices".

NOTE: THIS WILL ERASE ALL CONTENT AND SETTINGS ON YOUR DEVICE.

When this step is done, your iPad will behave like a new app. You'll want to connect to the WiFi again and install the Sonos app. When everything is ready, connect the iPad to the Mac again and start up Apple Configurator 2.

From the menu bar choose Actions, then Advanced and then "Start Single App Mode". You'll then be presented with a list, where you need to choose the Sonos app.

This will keep the iPad in the Sonos app even after reboots. You'll need to connect the iPad to the Mac and use Apple Configurator 2 again to disable Single App Mode again. The option is again found in the Actions menu under Advanced.


? is used in URIs for parameterization. Here it is enabling use of the location= which appears to be a port reference.
So, it would seem you're asking if you should drop it in your descriptor I would say yes.

I would suggest using rsync, which will sync all files and folders from a particular directory to another and skip over files it can't transfer because of damage. Use the following command to copy the entire root directory of your current Time Machine drive to a new drive:

sudo rsync -avxr --progress /Volumes/BadDrive/ /Volumes/GoodDrive

Due to the damage, you probably won't be able to continue using the new drive as a backup drive. It's likely that rsync will skip over some damaged files, causing OS X not to recognize it.

Another option would be to attempt to use Drive Genius to repair the existing drive. However, this probably won't work with an invalid node structure.

You could also use SuperDuper! to copy the existing files over to the new drive. However, you may run into the same problem as rsync in that it may not preserve the Time Machine file structure.

Good luck.


Why does MacbookPro Retina require the dedicated GPU to access external displays?

It's likely that the external display connections are simply wired directly to the discrete GPU. The internal display is connected to a gmux chip that handles switching between GPUs and it probably would have been significantly more complex to route the 3 external ports the same way.

I think it's fair to assume that most users connecting external displays will have AC power available, so this seems like a fine way to simplify things.

It's definitely not an issue of graphical power - I use an external 2560x1440 monitor with the new Iris Pro-only 15" rMBP and previously used it with an Intel HD 3000-equipped 13" MBP, both of which handle it fine.


Is there an app embedding the Flash player?

Google Chrome comes with its own instance of Flash that runs only when it needs it and only within the scope of Chrome. I have uninstalled Flash from all my Macs and simply turn to Chrome when I really need Flash for something.


Are all iPhones the same across carriers now?

No. In the US, CDMA models can work on GSM but the other way, not so much.

Worse, in the US, Sprint and Verizon are not willing to bring aboard a device from the other carrier despite CDMA and GSM potentially being technically compatible.

The GSM phones when unlocked work across pretty much any GSM carrier.
The CDMA phones when unlocked also work across pretty much any GSM carrier or the specific carrier that the device was assigned to initially. (So I would generally be able to bring a Verizon iPhone from another person to my Verizon account)


What does ~/Library/Application\ Support/Knowledge/ folder do?

knowledge-agent

/usr/libexec/knowledge-agent writes its databases to

This is Siri's proactive knowledge functionality. Siri will read data from the services you enable in System Preferences → Siri → Siri Suggestions & Privacy, writing data it finds useful into the database.


If your desire is to boot ONLY Windows on the machine, you can do this based on the setup you described by installing a Boot Camp partition and just setting the boot drive to that.

Since you have OSX installed on the machine, you should be able to find a utility on the machine called "Boot Camp Assistant". This tends to be in the Utilities folder of the Applications list. You should have a DVD of Windows 7 to get going with this since that Mac doesn't technically support Windows 8+. You'll want to start with 7 if possible since that way you'll get Apple's software support on the Windows installation. After that, you may be able to upgrade to Windows 8.1 or 10 but I've never personally tried it.

Normally installation of Windows is not a big deal, but without a proper "Apple Supported" GPU you might run into problems where the machine attempts to reboot into Windows and either goes back to the Mac or gets stuck at a black screen. In general, try to keep the Windows 7 disc in the drive and give the Mac some time to boot into Windows before powering off; for some reason, it takes maybe 20 seconds or more for the Mac to boot into non-OSX and you can get anxious that nothing is happening. If you're adventerous, there are some guides on the internet which should be able to guide you through a disc-less installation process that leverages VirtualBox.

Once you've got Windows installed, telling the Mac to boot by default into Windows is trivial: go to the System Preferences, Startup Disk and select that you want the BOOTCAMP partition to be the boot disk.

Going back to OSX without an Apple GPU can be done one of two ways:

Have the Apple Boot Camp software for Windows installed. There is a tray icon which has a selector to allow you to boot back into OSX.
During the Mac's startup sound, hold down Command-PR (the P and R keys simultaneously). Wait for the startup sound to happen a second time. This zaps the PRAM which will cause the Mac to boot the first OSX partition it finds.

both of these methods will probably require you to do the "Startup Drive" -> "BOOTCAMP" thing again in preferences.

Got it working? Great! Now the one downside of all this: your GPU will always run at PCIe 1.1 speeds unless you do something to the card. With some specific models, there are people on the internet who have figured out how to physically modify the card to run at 2.0 speeds (The MacPro3,1 is PCIe 2.0 for the 16x slots). I think this may involve cutting a resistor or something; you're on your own here. The other way is that you (ta da!) flash the card with an Apple EFI.

All said and done, you can make your Mac boot into Windows by default and have a Windows machine in a Mac Pro. However, if you can find an Apple EFI for your GPU, I would strongly suggest doing it since it'll just make life easier.


Fixing a corrupted OS X Mail structure after an import of mailboxes from the previous system volume

That "ugly" result is not a corruption or mistake, it's the way the Mail folder is structured now.

If you've been messing with its contents, I'd suggest emptying ~/Library/Mail/V2 and starting over again from your original source, re-importing or using Migration Assistant.

No, I don't know why either.


App will not open and will crash on every attempt

No, the app is either corrupted (which happens sometimes during the download) or as a serious defect that causes it to crash (and that Apple didn't catch during review).

You'll have to uninstall then reinstall the app.


Window too large when moved to second display

Try adding in a Keyboard Shortcut using system preferences. I have mine to execute the Zoom option located under the Window tab at the top of most browsers and applications. I changed the Command + Return + Shift from the default to my new shortcut zoom.

This will resize the window to fit the screen and if a different/smaller screen size is desired, you can easily resize it using the corners from here.

It is actually much easier to resize from this resized/"Zoomed" window because moving your mouse to any of the computer screen's edges will place you directly over the edge of the window allowing you do resize the screen without mis-clicking (example of mis-clicking: causing another window/application to become active or moving the position/orientation of the window altogether).

Just add in the application you want this shortcut to work for under the App Shortcuts option within the "Keyboard" -> "Shortcuts" sections of system preferences.

As long as any part of the top of the window is visible, then the following will work:

Hold down "Shift" while double-clicking then the window's title bar.
This will resize the window to fit your screen.


How can I use my iPhone's contacts with the new Google Maps?

You can try this app, Contacts for Google Maps.

It can create links inside your Contacts that will open the address directly in the Google Maps app.

Edit: I wrote the app.


Can you export or share Categories in Outlook 2011?

Sadly, and unfortunatly No. This is something I spend a few days on recently, and out of interest, it can't be done on the Windows version either. There is no way to keep these categories intact, and it can be a huge problem, especially when sharing items with others since the minute they make a change to a shared item, the categories are overwritten.

You could possibly however use an AppleScript to add them manually, I haven't tried thought.


Will stored emails on mail app be lost if I restore from a IPSW

You can't update to 9.0, Apple is no longer signing 9.0.


How does Safari (on iOS) decide when to present an SSL client certificate

Safari (or any other web client) doesn't present its client certificate unless requested by the website. So your client certificate is safe. The server is always the one asking for the certificate, sending along its own certificate. Therefore, your browser will see that the certificate do not match the one you have and will result in failure, unless the server sends the right certificate to match yours, in this case, you can be sure you're on the good website.


Is it possible to mute notification sound on ALL apps?

No.

Unfortunately, there is no way to do them all at once. You’ll have to do them individually.


Is it possible to decrease the size of the “activation area” for a hidden Dock in Big Sur?

This is not a real answer.  I am also frustrated by that behaviour but it seems like the scroll bar on some applications can and to avoid BigSur, has to be interacted with above where the actual scroll bar appears to be (ref grg's comment):

Another none answer is to decrease the dock size to the smallest size so that most of the time it's not in the way:

** edit **
I've now moved to dock to the left and made the icons bigger again.


I have had similar difficulties in the past. I have found a work around that may solve or assist you in your issue. I found that if I first extend the window vertically so the text all fits into it, therefore eliminating the need to scroll, it works correctly. Unfortunately, this won't work for long documents where it can not fit on the screen entirely.


Dual-boot Linux on a Mac with original Boot Loader without uninstalling OS X

1) Resize your OSX Partition, leave the space created as freespace (i.e don't create any partition)

2) Write the iso to USB and boot it (take the most recent image from http://cdimage.ubuntu.com)

3) Create ext4 for / where the freespace was created, use sda1 (osx: disk1s1) or use another EFI if you have more then 1 drive and you want to use the second for linux only - in short: use the EFI partition as the "bootloader" partition

4) Install Ubuntu (or any other distro) - but watch for the bootloader, if you don't want to use grub (care to elaborate, why?) you need to rebless the volume in os'x to boot through the normal bootscreen where you can hold ALT to fire linux.

I don't know what you want to achieve with that, since having grub is basically the same, and you will be loading grub from that screen anyways since you need to load the kernel somehow - guess there are other options but I never used them, just went with grub.

What I mean is that after you select the other partition with the normal bootscreen by holding ALT, you will load grub - since you must load the kernel, and there is now way to load it directly from that screen other then using MBR which even makes less sense since it's a UEFI system ;-)

note: I strongly advise you to use refit - it's a very good solution and has some extra functionality that will make multi-os setup's boot better.

If you don't like it, just rebless the volume in os x and you get rid of it.
bless is a system command- however in the new os x there is:

sudo systemsetup -liststartupdisks

and to setup back any Volume as the sys volume use:

sudo systemsetup -setstartupdisk /Volumes/YOUR_SYS_VOLUME_NAME

to check if it worked:

sudo systemsetup -getstartupdisk

So even if something goes FUBAR with the bootloader, it won't be any problem.

Why would you reinstall os x or anything else to boot linux on a Mac?!? Anyone doing reinstallations to boot linux is just a windows impared user who does not know how unix works, what gpt is and thinks of EFI as fancy bios.

How can I remap arrows keys to other short cut?

As you are a programmer you won't have any difficulty in editing Karabiner-Elements Complex Modifications yourself.

They are to be found at: ~/.config/karabiner/karabiner.json and can even be edited or expanded with BBEdit (or TextEdit).
Here's an example how I configured my own arrow key(s):

{ "description": "Up_arrow to Page_up",
  "manipulators": [
                   { "from": { "key_code": "up_arrow",
                               "modifiers": {
                                     "mandatory": ["left_control"] }
                             },
                     "to":   [ { "key_code": "page_up" } ],
                     "type": "basic"
                            }

Show folder a file is contained in with finder list view in OSX 10.8.4

Download Alfred 2. It is an excellent application that allows for a streamlined search of your computer's files, and it also allows has other uses such as opening other applications or webpages. It shows you the location of the file that you're accessing, so for example if you type "chrome" it will show the option of opening Chrome in its application location.

A useful shortcut is "apple click" which then opens up the location of the file.

Send/receive SMS (text messages) and place/receive calls from an iPad

Google Hangouts would do it. You'd have to get a Google account, and a Google Voice number, and then you can send/receive calls and texts with it.

If you had an iPhone i think you could also use the iPad to place/receive calls using the iPhone cell connection.  I don't think this is what you mean though


There are no Apple solutions for adding keyboards or fonts, only third party. Search the app store for Mongolian and try the Keyman app.  Unfortunately you have to upgrade to iOS 8 to have a keyboard that operates for the entire OS and not just via copy/paste.

Nobody here can tell you why Apple hasn't included some feature you want, but you can ask for it via

Paraview not accessible from other accounts

There is nothing wrong with your installation method. A lot of apps are intended to be installed by just simply dropping the app on the Applications folder.

Now either the packager/creator of the application bundle in the dmg made a mistake or the permissions of the bundle are deliberate.

To allow other users to use the app, modifying the permissions with the following command should be sufficient:

sudo chmod -R u=rwx,go=rx /Applications/paraview.app


Provided that you have made a backup of the data you want to keep via iTunes or iCloud it is safe to restore your phone from an old backup and later restore it to its present state from the backup you had made.
I would suggest using iTunes just because it seems more convenient to me and so as to you would feel safer about your data- an iTunes backup holds all the information necessary to restore your phone to its state at a set point in time.


Is there a software that tells for how long the computer has been running on battery?

In OSX 10.9 and above this is all in Activity Monitor app under the Energy tab.
It shows your battery life over the last 12 hours, and while it was plugged in is highlighted in green. It also shows you what apps are sucking on your battery and how much they are draining at the moment, and on average.


Safari 11.1.2 - Discord is not showing entire page or scaling correctly

I'm experiencing the same issue with Discord and Safari 11.1.2.  It started a few days ago.  Chrome does not have this issue.


Go to Preferences > Profiles and change the Working Directory setting from "Home directory" to "Directory:", then enter the path to your home directory. If your home directory contains spaces or special characters, this might fix the problem.

However, this doesn't explain the underlying cause of the problem, and is not an ideal solution. I'm posting this as the answer since it has worked for at least two people.


Start with force restarting your iPod Shuffle.  If that doesn't work there are three things you need to check:

The USB port is functional.  Try another device (any device is fine).  If it works, then you know your USB port is working.  If it's not, then you'll either need to use a different port (if available) or another computer

Check the cable.  The USB cable may be damaged and no longer allows for communication between the iPod and the USB port.  If possible, borrow one from a friend (preferred method), or you may have to purchase another one.

Verify that the Shuffle works.  If you can't get it to work (i.e. play music) then you definatley have a problem with the iPod.  If it will not communicate on the USB port, it's likely that the iPod USB interface has died.  It's unfortunate, but it does happen.


"Install Xcode.app" won't uninstall from my Mac

It looks like the application was removed, and launchpad just has not noticed this fact yet.


Writing AppleScript to change a TextEdit document from .rtfd file to .rtf

The @user3439894 comment provides a better solution but since this is tagged as applescript, here is an applescript answer.

Will prompt user to choose one or more rtfd, copy them to the desktop, turn them into actual folders, extract each one's text/rtf component to the desktop, and trash the unwanted bits. I don't know how you actually get the target files so I went with 'choose' and stuck to using the desktop as the workplace.

use scripting additions
-- Choose one or more rtfd
set aFilList to {}
set aFilList to (choose file with multiple selections allowed)
tell application "Finder"

    repeat with aFil in aFilList

        -- copy rtfd to desktop; collect name information
        set dFil to duplicate aFil to (path to desktop folder)
        set {adNam, ddNam, dwXt} to {displayed name of aFil, displayed name of dFil, ".rtf"}
        --> {"filename", "filename 2", ".rtf"}, or {"filename", "filename copy", ".rtf"}

        -- Remove 'd' from extension to reveal as type:folder
        set name of dFil to ddNam & dwXt
        set dFil to ((path to desktop) & ddNam & dwXt as text)

        -- Move rtf to desktop and rename; trash intermediary files
        move file "TXT.rtf" of alias dFil to (path to desktop) with replacing
        set oFil to (path to desktop) & "TXT.rtf" as text
        set name of alias oFil to (adNam & dwXt)
        delete aFil
        delete dFil

    end repeat
end tell


Yes, you can submit multiple version to iTunesConnect.  I often create my next 1 or 2 version 'placeholders' in iTC.  Just don't submit the placeholder versions for approval.

Your challenge, if you decide to do this, will be to keep all your versions and source code intact. Because of that, I don't upload the app package until I'm ready to have Apple review it.


There are a huge number of orchestration technologies out there from the trivial to the very complex (and expensive) running enterprise workloads across many other systems.
As per several of the comments, the easiest way would be to write 2 scripts:

To run on Mac 1 that tells Macs 2, 3, and 4 to run your second script
Runs your actual task, or, triggers and controls the app which runs your task.

The first script will run and connect via ssh, using pre-defined keys) and trigger the scripts.
It would help to have more details on the specific task you trying to run, but script 1 can be as trivial as:
#!/bin/bash

ssh user@mac2 'script2.sh'
ssh user@mac3 'script2.sh'
ssh user@mac4 'script2.sh'

and script 2 being something like:
#!/bin/bash

/run/some/app.app

Your original question was just "can you do this, and what's normal" - which is described above, so I don't want to go into a treatise on good scripting practice, especially without knowing your abilities and experience here.
There are also numerous answers on how to setup SSH keys for your Macs (eg. this ). In the above you'd need DNS to work, so maybe IPs would be simpler, and obviously user needs to exist as a user on the other macs, with the keys in place.
In recent macOS version zsh is the default not bash, but bash is there and functional as a scripting shell.

Employing a second medium of sound volume resistance?

There is actually a somewhat hidden step between 1/4 bars and muted. To select it, first set the volume to zero by holding the volume down key and then press the mute key.

Another way is to run osascript -e 'set volume output volume 0.5'. set volume output volume 0.1 and set volume output volume 0.9 are equivalent to set volume output volume 0.5.

You can decrease the volume level by using Soundflower together with AU Lab:

Download Soundflower from http://cycling74.com/soundflower-landing-page/ and download AU Lab from https://developer.apple.com/downloads/.
Select Soundflower (2ch) from System Preferences > Sound > Output.
Open AU Lab, set the input device to Soundflower (2ch), set the output device to Built-in Output, and press Create Document. You can then control the volume level from AU Lab and by changing the volume level of the built-in output from System Preferences.


Stop SuperDrive from checking for disks after wake up

You can disable the Superdrive if you set your account up under parental controls.

This should do the trick.


Automaticly file screenshots in folder on desktop

You can change the default screenshot location via the Terminal running the following commands:

defaults write com.apple.screencapture location ~/yourpathhere
killall SystemUIServer

In your case to save the screenshots in a folder on the desktop the path would be /Users/userName/Desktop/yourfoldername


You will need to install a DNS server. If you need a DNS server that automatically synthesizes answers from the contents of /etc/hosts, use dnsmasq.


How can I create a photo slide show of one face from iPhoto's faces?

First: You can't do it with iPhoto, it's just not a feature.

Next: Those faces thumbnails are stored inside the iPhoto Library package - in the Data folder on some versions, the Thumbnails folder on later ones.

If you make an alias to that folder you could possibly access them that way using another app. However, they are scattered hither and yon throughout the folder, in multiple subfolders and may well be difficult to find. That said they include they all include _face0 in the filename so a Smart Folder will help find them

But... However, these are very small (200 - 300 pixel on the longest side) images and it's unlikely that they will perform well in a slideshow.


From time to time I have had this "create account" page appear for what seems like no reason.  In my case, there was a reason.

You may have already been logged in to Apple's single sign-on with an Apple ID that hasn't yet been set up for use with the developer forums.  When this occurs, the forums site picks up the login, notices that the logged-in Apple ID is not "forums ready", and forwards you to the "create account" page.

To get past this, you can go to developer.apple.com's "Member Center" to sort out your login, then return to the forums web site.


If the two devices are named the same it will backup/restore the same items. My recommendation is to rename one of your devices and a new profile will be created for it.


Removing FileVault2 key from memory on lid close

In addition to the destroyfvkeyonstandby option, you also need to specify that pmset is setting hibernatemode 25 for the power management options.

sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25

Setting both options ensures that the Mac in question will hibernate (where the contents of the RAM are written to disk) and also have the FileVault 2 key automatically removed from the saved RAM.

When the laptop is awakened from hibernation, you should see your account icon and a password blank at the FileVault 2 login screen, which would indicate that it had been asleep.

When this setting is set, you may run into some Power Nap-related issues. I have a post on that available from here:

Power Nap, power management settings and FileVault 2


"sudo apt-get install" on OS X Mavericks

If I understand correctly, you just want a package manager.

apt-get is just an interface for Aptitude, a deb packaging system. DEB isn't tied into Mac OS like it would be your average Linux distro, so you'd need an alternative.

Fink will do this on its own, other alternatives are MacPorts or Homebrew.

If your goal is to be able to execute a command, say like (something) install program and it'll install the program and its dependencies for you, either of these three will do that for you.

I'd personally suggest Homebrew. http://brew.sh/

Clone the disk image of an iMac to a Mac Pro (or MacBook Pro)

Short answer

Generally what you want to do should be fine, however there are some considerations (see long answer below).

Long answer

In years gone past macOS installations were configured as part of the installation process specifically for the hardware it was on. However, for quite some time now this is no longer the case. So, doing what you want should be largely possible, although you may have some minor issues that are inherited. For example:

I have seen situations where the computer name doesn't reflect the actual computer of the installation, although this doesn't pose any actual problems as numerals are typically appended at the end to distinguish between computers on the network
some software may not work initially as the software is simultaneously installed on multiple machines and therefore exceeding the software license

Another factor to consider is that not all versions of macOS will run on all Macs. For example, let's say the installation you love is on a 2015 iMac that's running El Capitan 10.11.6. If you clone this and then try to use it on a 2017 MacBook Pro with Touch Bar, it won't work because Macs cannot run on any version of macOS that is earlier than the version that shipped with the Mac originally. This is managed via the firmware and there's no getting around it.


iMac keeps restarting every couple of minutes. Any ideas which software/hardware is the culprit?

Based on this log I see 2 problem makers.

One is the "Symantec" that you should remove.

The second one is the "logmein" that you should also remove.


Photos.app: Unique smart album criteria for identifying iOS screenshots?

Screen captures do not have a camera on the metadata. You can use that to weed out most of the pictures as all pics taken with the integrated camera will state the iPhone model (and even if taken with the front or rear camera).

Second, as @bjbk said, all screen captures are .pngs.

I tried a text filter for each resolution, including one for landscape and another for portrait orientation. I couldn't reproduce the behavior described here, which states that it does not matter the order of the dimensions. You will have to track down each dimension pair relevant for your case.
Moreover, I couldn't catch all screen captures when adding this filter; in a seemingly random fashion, some pictures were correctly selected for each resolution pair and others with the same resolution didn't.
I checked the metadata on Adobe Bridge to find out what was the difference between images but could not find any.
Also important, the dimensions of the screen capture differ from the dimensions of photos taken with the device:

iPhone 6:

Screen captures: 1334 × 750
Pictures with rear camera: 3264 × 2448
Pictures with front camera: 1280 × 960

So that won't be a problem for filtering; anyway, the Text filter did not work as expected.

All in all, a filter made by selecting Filename - ends with - .png AND Filename - starts with - IMG_ AND Camera Model - is empty gave me the best results.

I didn't try regex because I can't get my head around it; I've had some success following guides when I find which version / syntax is appropriate for the case at hand and a good guide, but I don't really understand it.


Would AirTags be useful if you lose your item in a unpopulated area?

Your iPhone scans for both AirTags it knows and ones it doesn't, and updating the location for both ‘types’ of AirTag. This means you are correct that your iPhone would show the last location it knows for your own AirTags even if that location is not updated again by anyone else.


Which temperature sensor represents the CPU on my iMac?

They're all valid temperature. It's kind of like asking "what temperature is my car's engine?" There's the oil, water, pistons, camshaft, etc. that all have different temperates. Just monitoring the oil temp won't tell you that one of your pistons has overheated.

But here's the thing, your computer won't overheat. Most (if not all) modern CPUs "thermal throttle" when they reach a limit placed by the manufacturer or motherboard. In this case, that'd be around 100°C for most modern Intel CPUs. Thermal throttling means the CPU will run slower, therefore using less power, and thus not heating up as much. It's perfectly fine to run a CPU at it's max temp for years, it's designed to be used and won't "overheat". If you prefer, of course, you could turn the fan up higher (or reduce the workload), but that won't really have any effect on your CPU's lifespan.

To directly answer your question, I have Macs fan control, I usually just set it as the first core, but I've figured out that one of my cores is hotter than the rest, and I just use that. CPU PECI seems to be some sort of average or entire die temp, which should be fine in most cases.


In Calendar, what does "turn of shared calendar messages in notification center" mean?

Yes, that makes them shared.

My wife and I have a few iCloud calendars that we share. With this option not checked (as it is in your screen shot), if she made an adjustment to one of them on her iOS device or Mac, I would have a new notification on my iMac notifying me of the change.

Similar to this screen shot, but instead of saying 'Coffee in 24 minutes', it said '[other persons name] changed [event name]' or something similar.

If you check that box, these notifications would be suppressed. This feature was annoying me (because of another bug, many of our events had alerts put on them that we didn't want, so I checked this box so we didn't go crazy trying to fix them). Something similar may show up in iOS 6 as well.

Finally, I have only used iCloud calendars with this, so I am unsure if it works exactly the same when using a shared Google calendar. I would assume it would since its still going to the same store, but have no way to test.


Is it possible to access an iPhone over SSH on 3G?

a) Unless you have jailbroken your device, iOS doesn't have an SSH server to run.

b) If you have jailbroken your device, it will not be possible to SSH into your iPhone over cellular. You are behind one of the most complex NAT setups there is. When you move between towers, and lose signal, you lose your lease to a unique ID with the cellular network (like an IP). However, every time your connection is re-established with your carrier, you're connected to a new tower and your connection is routed differently through another NAT and finally out somewhere, probably in another state.

In researching this alone, over the course of 10 minutes, my iPhone returned 2 different IPs from the internet, one in Florida, one in Pennsylvania.

Short answer: Wi-Fi = yes | Cellular = no


Apple's manuals are online: https://manuals.info.apple.com/MANUALS/1000/MA1639/en_US/mac_pro_mid2012_ug.pdf but they don't say IEC320C13 on Mac end.

In the US - you're looking for NEMA 5-15P to IEC320C13 like https://www.amazon.com/C2G-Cables-14719-Universal-IEC320C13/dp/B000067RTS

The MacPro are all standard cables, so get whatever wall configuration you have in your country for any PC with a standard power supply. Basically, any hardware or computer store will be able to hook you up since Mac power supplies are international in terms of 50/60 Hz and 110/220 VAC.


Managing iCloud Keychain Accounts on iOS

Apparently this feature is only for macOS and is not implemented at all in iOS. Which of course makes no sense since the primary benefit of this feature for the majority of users would be to set up accounts on their computer and then transfer them to their phone. Also it's been about 5 years and still this feature remains half-implemented. Bummer.


Unable to open Anywhere option from Gatekeeper in order to open apps not from Mac App Store

If you download an application from the internet, then the following steps can be taken to open the application. Here the Startup application is used as an example.
I downloaded the Startup application from the SourceForge project Startup for rEFInd. Here is my Downloads folder.

Note: In Finder preferences, I have Show all filename extensions checked off.

When I double clicked on Startup.app, I received the following popup.

I selected the Cancel button. Next, I opened the Security & Privacy pane of the System Preferences application, as shown below.

Here, I selected Open Anyway and the the following popup occurred.

Here, I selected Open and the application opened.

The above steps only had to be done once. Afterwards, the application could be opened by simply double clicking on the icon.

Note: The above steps did not remove the com.apple.quarantine extended attribute placed on any files or folders.
How to Avoid the Above Steps
When a file is downloaded, the extended attribute named com.apple.quarantine is placed on the file. This is what initially kept the Startup the application from opening. The following steps can be taken to remove the com.apple.quarantine extended attribute from the application.

If you want to test these steps, then you will probably what to put any existing Startup application in the trash, and download a new copy of the application.

Right click the application in the Finder window and select New Terminal at Folder, as shown below.

This will open a Terminal application window, as shown below.

Enter the following command, as shown in the image below.
xattr -rd com.apple.quarantine .

Next, close the Terminal application window. Now you can open the application normally.


Can I connect my Macbook Pro to a Windows 10 PC via usb-c for more than just power?

Your PC is not a keyboard and mouse, so no, it cannot be used as a KVM.

Just like your Mac, the keyboard and mouse on the PC are USB devices - it's just like a regular mouse and keyboard, just permanently plugged in.  They are "end devices" and your PC doesn't present itself as an HID device so there's no way for your Mac to see the PC as an input peripheral.


'True' Thunderbolt to DisplayPort or DVI cable?

I took a look at Belkin's website on this particular product and they clearly state that it "Supports dual displays & 4K cinema resolution."

Now, there is no "Thunderbolt" to DVI/HDMI because Thunderbolt is an extension of PCIe.  So, in a very basic sense, this would be like trying to plug your monitor in directly to the logic board and not go through the video adapter; it cannot happen.

However, Thunderbolt "multiplexes" the DisplayPort signal on that single cable.  You are going to get both.  Now, if you use a a Thunderbolt compatible cable, you can daisy chain additional TB devices off your monitor, albeit at a reduced data transfer rate.  This is why monitors are the last in the chain.  If you use a non-TB cable, you will only get display and no TB signal.

EDIT:

It was really bugging me that this didn't work because I was close to reccomending this product for a friend and I wanted to do my due diligence.  I found this on their support site:

So, basically, in order for you to get dual displays, you need a native Thunderbolt Display like these.

If you do go that route, remember you will need a Thunderbolt/Thunderbolt 2 cable


How do I request a read receipt when sending e-mail with Outlook for Mac 2011?

Outlook:Mac doesn't have the read receipt feature.

And, frankly, you shouldn't use read receipts.  Most mail clients can be set up to simply ignore read receipt requests.  If the mail client isn't ignoring read receipt requests, then it gives the reader a message asking if the reader wants to send a read receipt; many people select no.  The existence of a read receipt doesn't actually tell you whether your reader read your mail.

Open it in Preview.

Hit  Cmd ⌘    i   for Inspector, then the 2nd tab (info, i in a circle) & then Exif - should give full info, unless the originator was clever enough to remove it.

It is possible that the sender has set iOS to strip these fields from the photos and it's also possible that they are stripped if the image size is reduced. You can also use tools to manipulate / falsify the data, but in most cases people don't mess with changing the defaults.


Both the fact that it is independent of the OS you are running and that it disappears after some time/warmup period indicate that this is an hardware issue. Take the laptop back to the place you've got the video card changed to have it fixed.


Could running laborious code for many hours damage my mac?

Well, make sure your computer is on a solid surface with space around it to permit a good flow of air.

If you can have it in a cool room instead of a warm room would help.

A computer getting warm when working hard is not a problem, but if it gets too hot is - so you should check the temperatures if possible - a fan control program is a possibility.

One other possibility may be to pause the running program and allow the computer to cool down but this may not be possible...
