Disable ESC key yielding list of word suggestions when pressed in Preview in OSX 10.11.2

It's the auto completion from the built in spell checker and after a lengthy search I found the solution in Apples Discussion Forums:

defaults write -g NSUseSpellCheckerForCompletions -bool false

Afterwards restart affected programs and Esc just cancels searches again.


Is there any real-time text-to-speech software?

Dragon Naturally Speaking v6 may be an option. Trial available here. Have used with school and it performed well in loud environments as well as those that are quiet. Doesn't need an internet connection after downloaded, so is a very good idea. Also, the macOS built in dictation software may be downloaded for free, but is not as reliable.

For more, see this thread, which says

  eSpeak is a brilliant opensource text to speech project. It's the default TTS software on many Linux distributations, but there's a Mac version available and it works great. There is also a project based on eSpeak called Mbrola which adds "singing" functionality.


cannot boot. volume disappeared from boot option after Disk Utility (GUI) repair

You managed somehow to kill your EFI. (EFI is the boot loader)

EFI is in a Hidden partition on your hard drive.

Obviously you found it and kill it?

Just to say, in reading your activity, you do mess around to much.

Macs do not need regular maintenance specially not using Recovery mode.

You can get help from here to get a copy of the EFI.

MacBook pro 2017 touch bar model.. Horizontal Lines on screen

The LCD is failing, sounds like. You've essentially already proved this by taking a screenshot that does not display the issue you are seeing (the artifacts). This happened on my SO's 2013 MacBook Air. I believe it's a fairly common issue, sorry to say.

Looping is a function of the player (i.e., QuickTime). You can copy the clip and paste into the timeline of an iMovie project several times to create a loop effect if you want, but it will only play as many times as the clip is copied into the iMovie project.


Close all Mac OS X apps before shutting down
Try to determine if one particular app is causing the problem. Maybe one app always aborts the shutdown process. Try updating to the latest version.
Open Disk Utility. Choose the your main hard drive and click Repair Disk.
Usefully shutdown freezes are caused by incompatible or outdated drivers e.g printer, scanner software. Open OS X activity monitor. Do you see any high cpu processes or unresponsive applications that are marked red?


Which is the most powerful fan less iMac that uses a CRT for the display?

Is Lion server really a valid server for small business?

I've never tried any of the Mac Server products. But AnandTech has a pretty good in-depth review of Mac OS X Lion Server. A few of the conclusions:

  ...server administrators will be happy to know that, in spite of its deeply cut price and consumer-friendly distribution method, Lion Sever stacks up favorably against Snow Leopard Server.

and

  OS X Server is most useful in a handful of different scenarios: the first is that you have a small network that’s in need of a full-featured but easy-to-manage and simple-to-license server product. The second is that you’re managing a network of any size that used to be all-Windows, but hosts a growing number of Macs (this is often the case in education, for example) - OS X Server knows that it’s going to be finding its way into a lot of Windows houses, and as such it integrates fairly well with existing Active Directory setups. The last is that you have a bunch of iOS devices flooding your network and you have no idea what to do with them - iOS management may be Lion Server’s ace in the hole.

(emphasis mine)
Seems to fit your intended usage pretty well.

About your other question:

  Besides, and this is a bonus question, do you have some experience in using Lion server to manage centralized Xcode development? (we currently use our own MacBooks and we keep in sync using Git, I'd like to know for different approaches based on OSX Server).

Keep using git, use the OSX server as central repository (maybe consider buying GitHub Enterprise or using an free/open source alternative for managing your git interaction). Install a CI-tool (Jenkins or similar) on the server and use it to create automated builds. Should work quite nicely.


How to add a user from the command line in macOS?

A similar tool to useradd is /usr/sbin/sysadminctl on macOS . There isn't a manual but /usr/sbin/sysadminctl -h is explanatory. You should be aware that the command and options will be stored in your shell's history. Note the last line of the help output so that the user password is not stored in your shell's history.


"to its max" is extremely vague, especially as you didn't really tell us much about your existing configuration.

But here are some 'max' specs you can run on a 2012 Pro

Max RAM - 128GB in dual channel or 96GB in triple channel.  ~$400 (but only if you have a dual CPU) - [OWC]
Max Graphics - Nvidia GTX Titan X or AMD RX 5700 - [macvidcards] $675 - $800
Max OS - generally High Sierra with NVidia or Mojave with AMD.
Max Drives - 7. Four in the regular bays, one above the optical & two on a PCI card - [Mac Pro PCIe SSD Hardware Options]
Max CPUs - dual 6-core Xeon 3.46GHz - [OWC] $1,379
Max Bluetooth/WiFi - [macvidcards] $175
Max USB - 4-port PCI USB 3 card - [innatek] $30 (but many of these type of card are incompatible with newer OSes 10.10+))


This term configurable refers to the fact that when you order a Mac from Apple you can choose to configure it with more RAM. You cannot do this after purchase yourself, as the RAM is soldered on during the manufacturing process.

Other configurable options when buying a Mac usually include the size and/or type of storage, the processor you wish to have, bundled software, and so on. The choices you get also depend on the model of Mac you purchase.


why is the touch screen on my iphone 4s not working correctly?

Assuming that you haven't jailbroken your phone, the most likely culprit is a hardware part called the digitizer. If you live near an Apple Store, you can get get a free diagnosis of what is wrong by making an appointment at the Genius Bar. The repair will not be free if it is indeed a hardware problem, but then you will have a starting place.

If you have a good up-to-date backup of your device, you can try restoring the operating system. Please be aware that the process of restoring can result in serious data loss (including text messages and photos) if you are not careful.

How to determine if my iPhone XS is Fast Charging?

There’s no on-screen indication of the charging speed on current iOS versions.

why is aperture filling up my local mac disc when exporting a video to external drive?

I'm guessing it's using the boot drive [its own Library structure, in fact] as a scratch disk & making the video as raw data, which it will then compress & copy to the desired location.

You cannot dictate which drive it will use for scratch, unlike Photoshop, so the only thing I can think to 'fix' it [other than start deleting stuff] would be to move the Aperture Library to a larger drive. Double-clicking the 'new' library will launch Aperture with that as its new default.

You could always move it back afterwards.

Changing the horizontal scroll speed on a corded Apple mouse

You mention that you have the latest MacBook Pro and a mouse with a 'wheel'? Is it an Apple corded mouse? There are two current models available - Magic and Corded with a 'tracking ball', so my immediate thought is you haven't got a Mac branded mouse (dont think Apple have ever made a wheel mouse) and there in lies your issue. If its the latest tracking ball corded mouse then you should be able to set tracking speed in the preferences. Note: the System Preferences / Mouse panel on Mac 'changes' dependent on which mouse it detects to reflect the capabilities of that particular mouse... if it isn't detecting horizontal scroll capability you wont see this in the preferences panel and it may be running on a default preset coming from the mouse itself.

Here is a screen grab of mine (running a magic mouse) - the tracking preference is universal vertical / horizontal so only one is shown.

Apple have built the scroll speed control into OSX so its odd that your mouse is reacting this way. I would be thinking broken mouse*, 3rd party mouse driver issue. The way to check that is to 'borrow' a colleagues working Mac mouse (see if it behaves differently on your Mac) or get on eBay and buy a used one for $20. Could be with you in 2 days.

Apple mice can part fail. I have two currently with issues - one over sensitive and clicks when I don't want it, one with intermittent random scroll speed issues (which might be the laser failing).

Link to help:

Apple Mice Variations over time on Wikipedia.

Tip: I work on Mac everyday to deadlines so part of my support kit is a bog standard Apple Pro Mouse (M5769) circa 2003 which I have used on multiple Macs to keep me working - its on my MacBookPro OS 10.8 right now for Photoshop as I prefer scrolling OFF in that programme. The Pro Mouse has no scroll function and I don't need a system hack, just plug it in. Two mice on the same Mac works fine and does not affect the Magic Mouse performance at all.


How to change shortcut used for temporary zoom (accessibility feature)?

I found a limited solution:
Install free BetterTouchTool from http://blog.boastr.net
Go to Gestures/Normal Mice, click Add New Button, set Left Click, check ctrl and option modifiers.
At right, choose Predefined Action called Mouse Click Actions / More Mouse Buttons & Modifiers, and simply choose Left Mouse Button (see attached image). Save, close the BTT window, and try left-clicking. Unfortunately clicking is the only thing you can do, for example you can't click+drag (at least it didn't work for me).

Mac - Output different audio streams to two separate devices

I wrote all this before realising you want two routings from one app - that's not going to be possible. I'll leave this here for future searchers.

There are only two apps I know can do this, both by the same company, Rogue Amoeba.

The cheaper & simpler one is SoundSource - $35. There is a more complex/expensive one which can also record any sound source to disk as well, called Audio Hijack - $70.

SoundSource can do all you asked & more.

There is a late third - Boom2 & the newer Boom3D - but it's a notorious crasher & speaker destroyer unless you switch off everything except the routing [judging by the many questions we've seen in here about it. I've never tried it personally].

Can I set my Mac up to take a screenshot everytime I left click?

I have my doubts that mapping left click to screenshot is a great idea. It renders mouse as pointing device useless and you may end as some Vim users: "I've been using Screenshot for about 2 years now, mostly because I can't figure out how to exit it."
To set folder where screenshots are saved:

Press ⇧⌘5 or open Screenshot with Spotlight (⌘ Space; enter Screenshot in Spotlight search field).
Select 'Options', and set 'Save to' as one of defaults or 'Other locations.

To take screenshot (full screen):

⇧⌘3

This takes screenshot of full screen and saves it to folder set.
I think that pressing three keys is simple enough solution. It takes advantage of the workflow built into macOS, no need for Automator scripts nor remapping.
For more information have a look at Apple documentation: Take a screenshot on your Mac


How to prevent iTunes from trashing older versions of apps on updates?

I solved this by setting up a folder action using Hazel to automatically move any file in the trash with the extension .ipa or which is otherwise recognized by the system as a Mobile App to my iTunes/Mobile Applications folder. I'm sure you could set this up without using Hazel, just using folder actions. You will need to make invisible files visible before setting the action so you can at Trash as location A.


Search files by size or star-rating using spotlight

I'm trying to search files by their size or star-rating using Spotlight. I know it can be done using finder's Command+F, but I cannot figure out which is the syntax I should be using in Spotlight's textbook.

Here's what you need to do:
Use the search criteria, like this:

If you click on the menu there that says "Kind" (which is the currently selected criterion), you get a popup menu with options:

Choose Other... to get the complete list of possible criteria:

I think the one you're looking for is Rating, which is the user rating value. Click the checkbox on the right, as I have, to add it to the items that show up by default in the popup. Now you can add that as one of the criteria you're using to search, along with Name, Kind, etc. There are some other interesting photography-related criteria in the list: Exposure Time, F-number, ISO speed, etc.
Here's why it won't help:
In order for Spotlight to find files using attributes like Rating, some importer has to first provide data for that attribute to Spotlight. None of Apple's own photo storage applications (iPhoto, Aperture, Photos) seem to provide an importer that does this, and unless your favorite photo app does provide that data, Spotlight won't have any data in its index to search for.


Python is shipped with Macs, you can just use SimpleHTTPServer to respond to HTTP requests.


SSH accepts single argument as a command, not multiple ones, so the command line should look like this (note the quotes):

sshpass -p Password ssh maliciouzzhd@10.0.0.1 "export DISPLAY=:0 & mate-session-save --force-logout"

But the general idea might not work, because you didn't allow X11 forwarding (add -Y switch to the ssh).


How can I launch a printer scanner from Spotlight?

Easy,

Open System Preferences
Select the "Printers & Scanners" control panel
Select the Scanner that you want to create the shortcut for
Once the scanning window opens, right-click on the Scanner's application icon on the right side of your dock, and select "option/keep on dock"
Next time you want to open the scanner, just click on its docked icon
If it is a combo printer/scanner, step 5 may open the printer queue window instead of going straight to scan mode. If this occurs, simply the click the "Scan" button that shows in the Printer Queue window.

Is the "Lookup in Dictionary" context menu option hardcoded in Google Chrome for Mac?

What you are seeing are the OSX built in Text Services, such as Spelling and auto-correct services when dealing with anything in OSX that is text.

These services are automatic for the whole OS and cannot be turned off and are available in every application

Note: Spelling Auto-Correct can be turned off/managed in System Preferences -> Languages & Text -> Text

The "Services Manager" and the "Dictionary Service" only relate to what is shown and provided in the Services Menu within running applications.  you can turn off those within (oddly enough) System Preferences -> Keyboard -> Keyboard Shortcuts -> Services


Should I restore my data before or after upgrading the OS?

It won't matter as far as the software goes since Lion runs the migration script one time only on your Snow Leopard data whether you migrate it in from a backup or it's there when you do the upgrade to Lion.

From a human standpoint, I would encourage you to make a "test" account (pick a different short name to prevent conflict or confusion when migrating your "real" account later)

Updating and testing Lion lets you build confidence the Lion is working on your repaired hardware.

Run Snow Leopard updates to 10.6.6 at least to get the App Store if needed
Install Lion
Run all updates
Test Lion in the test user. Once you're happy it works, migrate in your user data.

There's no right or wrong here - so do whatever makes the most sense to you. You've had a rough spell with the first upgrade / hardware failure - no need to over complicate things unless you really feel more steps is better.


Apple Mail: Save Disk Space or only load some Mails

I doubt that changing your Apple Mail settings is going to help with your disk space problem (I've got more mail items than you do in my IMAP accounts, but my Apple Mail folder in ~/Library/Mail/ is under 1 GB), but leaving that aside, here are some ways to address the question that you have posed.

If offline access to your email isn't important to you, you can simply not have Apple Mail store your email locally.  To do this, in Apple Mail, go to Preferences -> Accounts -> [your Gmail or iCloud account] -> Advanced, and select "don't keep copies of any messages" under "Keep copies of messages for offline viewing".

If offline access to your email is important to you, there are a couple of options.  There are a couple of options in the aforementioned "Keep copies …" dropdown menu which might help you, such as not keeping attachments or only keeping mails which you have read.

If you'd like to redirect mail from Gmail to your uberspace.de account, that is trivial.  In Gmail, open your Settings, select "Forwarding and POP/IMAP", and then select "add a forwarding email address".  Gmail will send a confirmation link to the email address that you provide.  After that, back on that same tab, select this email address to forward to and choose what you want Gmail to do with the forwarded email (keep it, archive it, delete it).  (Gmail's full instructions for this are here, which includes links to information about how to filter email that you forward.) In Apple Mail, you would then disable downloading new mail from Gmail and enable it for this new account after you've gotten qmail set up to your needs.

If you'd like to redirect mail from iCloud to your uberspace.de account, that is also trivial.  In iCloud, open the Settings (lower-left corner), and enter the email address to which you want your mail forwarded.  You can choose there whether iCloud should delete the mail it forwards, and I presume that you would thus not have Apple Mail downloading your iCloud mail.


Is it possible to make an application’s window smaller than intended?

No.

You can't force an app window to get smaller than the minimum size it is programmed to be. There's no 3rd party app or macOS feature that can let you do otherwise.

It's clear that it's not a hardware issues since the sound works in certain scenarios. It seems to be a software based issue. I would suggest backing up and restoring the device using these steps. Make sure you set it up as a new device so as not to transfer any old software back to the phone after the restore.

iPhone 4S speaker not working for apps but works for ringer

I had this very same issue, after some research on the Apple Discussions forums I found out that it was due to either the docking connector at at the bottom or the headphone port either needing to be cleaned or that one or both may have been damaged. If you have tried using headphones and can adjust the sound with headphones in this would lead me to believe that this is indeed the most likely scenario.

In my case it was likely to be water related (as my flatmate didn't screw the top on the water bottle in my gym bag and the water got in my phone). If it has been water damaged then you might be able to get some of the water out using silica gel (available on Amazon). Place the silica gel around the powered down phone and seal tightly and leave for at least 48hrs. This should absorb some of the water.

If the damage hasn't be caused by water, you could try cleaning the headphone port and dock connector. You can use a soft bristle toothbrush for the dock connector, again while the phone is off, and give it a decent clean, being careful not to press too hard. You could also use some alcohol here but be careful not to use too much.

The headphone connector can be cleaned using a Q-Tip and alcohol while the phone is off. It needs to be left to dry before turning it on again but it should clean up the headphone port nicely.

If none of this works then it is likely that there is something else wrong with the phone and it would probably be best to take it to Apple, or a third party repair company for them to have a look at it.

Export iPhone or iPad Backup to an external hard drive

Yes - Apple documents the folder in which iTunes saves backups here:

https://support.apple.com/en-us/HT204215

Apple doesn't make tools to poke at those files and export the data, however.

The apps themselves are saved in the iTunes library - so you can move them easily. The data embedded in apps depend on how the developer of that app chose to store them. Many use sqlite and xml and other standard data formats, so it's not unreasonable to get at many of the files - some are even stored with odd names, but still the correct image and sound and movie file formats.

Problem internal partition macOS high sierra

You made partition 2 type 53746F72-6167-11AA-AA11-00306543ECAC. You should have made partition 2 type 7C3457EF-0000-11AA-AA11-00306543ECAC.

The commands to change the type are given below. I assume you are entering the commands from macOS Recovery or from a installation flash drive.

gpt remove -i 2 /dev/disk0
gpt add -i 2 -b 409640 -s 781050984 -t 7C3457EF-0000-11AA-AA11-00306543ECAC /dev/disk0

Blanking plate for MacBook Pro optical bay?

I have never see anything that covers the area where the slot is, so cannot really help with your query specifically, although I did spend a long time researching the whole caddy thing when I did the same to my iMac, and I've never found anything.

However, I would advise you to blank it off from the inside, with some electrical tape or other, to prevent dust ingress through the slot.

Any external blanking plate, (presumably to remove the temptation for someone to try to use the slot left behind?) is going to be more unsightly that the slot, in my opinion, unless it is perfectly machined out of the same aluminium as your laptop.  I'd be happy to ensure that the opening is secured from dust, and not worry about the aesthetics of a pointless hole, because the alternatives will almost certainly stand out more.

iOS 9.3.5 recover photos with broken touchscreen

After a lot of other ideas the person I was doing this for was able to give me an old WiFi network that the iPad had connected to. Once I had internet access on the ipad it was "easy"
Using Siri I enabled voice over (Say "Enable Voice Over").
Then I went into bluetooth settings and switched on bluetooth whcih I did by asking siri for the bleutooth settings and then using Ctrl+Alt+Space (Ctrl+Option+Space on a mac keyboard) to switch it on. Once It saw the bluetooth keyboard I had prepared earlier I again used Ctrl+Alt+Space to pair with it.
Once I had the Bluetooth keyboard paired I connected the iPad to the computer using the cable and then used the bluetooth keyboard to Ctrl-Alt-Space the allow button and thats it. All data is being recovered now.
It is nothing short of a nightmare to navigate on an iPad with a keyboard but it is dooable.
I had already tried a digitizer replacement but it appears that the connection in the iPad was damaged as its digitizer worked on another iPad and none of the digitizers I had worked on this one. I do not belive it would have been possible to do this without getting it onto the internet.


Mojave App Store Only Shows "Updates" Tab

Never mind, just figured out an easier way to resolve this:

Spotlight > System Information.
In the lefthand column, locate Software > Applications.
Find "App Store" in the list. If there are two versions, click the older one and identify its location.
Navigate to that location in Finder and confirm (via right click > Get Info) that it's the older version. Delete it.

Voila!

How can I avoid seeing an Apple ID password field on my iPhone 5?

Instead of just canceling each time, give the app that is requesting it your Apple ID password.  The phone should remember the password for that given action and not bother you again.

Or perhaps your password has been corrupted so try going to Settings/iTunes&App Store, tapping on the box that says "AppleID: youremail@some.com", and signing out and then back in again.


@user2421192's comment had the solution: apparently the bubbles are automatically scaled proportionally to the range of the radius data. So by adding a new row at the top of my data, without x or y data, but just a r radius value, rescaled the rest of the data.

Since the radii I have don't vary by much, I decided to modify them with a formula, taking the exp of the original radius r divided by ten (exp(r/10)), and then setting my "scale" radius to 50 * max(radius) (of the rest of the column), which gives some variation in the bubbles that makes it a little clearer whether they're bigger or smaller than the rest.


Virus in Safari preventing it from launching?

The folder you mentioned is ~/Library/Saved Application State/com.apple.Safari.savedState

You can find it like this…

Switch to the Finder & hit ⌘ Command-N to generate a new window.
Hit ⌘ Command-⇧ Shift-G for Go To…
Copy/paste the following [including the tilde ~ sign]

~/Library/Saved Application State/com.apple.Safari.savedState
Click Go
Delete the entire contents of that folder; it should be just a few files called data.data, window_1.data and windows.plist

Try launching Safari again.


I have an OS X client VM within VMware Fusion.  It does have a serial number (starting with VMW...).  This is different to the host Mac.

VMware Fusion seems to generate the serial automatically, but it is not obviously stored in the vm's configuration files.  Also not mentioned in the vm logs.  My guess is that it is 'burnt' into the .nvram file when the vm is created or copied.

As you know the UUID can be changed, but the only references I can find to changing the serial number relate to downloadable OS X vm images.  For example: Change serial hack  This supports my guess in the previous paragraph.

Legal? Using downloaded images breaches Apple licenses - but you are not doing this.  Serial number: Not so clear as it does need to be globally unique - it would be bad to change it to a value used by another vm or physical mac.

But, I don't understand your need to change the serial.  VMware will make sure it is unique if you copy vms to create development and test environments.

How do I access LastPass Passwords on iOS/iPadOS from web browser?

Chrome Users:  Please note that LastPass has problems in iOS/iPadOS and as of 13.3.1, the fault is still present. All is not lost however as LastPass in the below example is tested and known to work correctly with Firefox as of iOS/iPadOS 13.3.1.

iOS/iPadOS Settings

Open Settings
Choose Passwords & Accounts
Select AutoFill Passwords
Check the box next to LastPass
Uncheck the box next to iCloud Keychain.

LastPass App

Before you can access any passwords, you must have the LasstPass app installed on your iPhone/iPad and be logged-into the App with your LastPass Master Password

Web Browser

Although this example uses Firefox, the process is almost the same for Chrome users.

Step 1

Select the password field.
Open the share dialog by tapping on the 3 dots (Chrome users tap the share icon).
Choose "Share Page With..." I did say the process was counter-intuitive...

Step 2

Tap LastPass

Step 3

Tap the password offered in the LastPass dialog.

That's it.

Conclusion

Although not a very intuitive process, using LastPass with a browser on iOS/iPadOS it's still pretty easy to use.


Maximise to half screen and choose other window

I worked it out.

A long press on the green button then allows you to drag it to the half of the screen you want. (Better touch tool not required, default MacOS behaviour)


Smart Mailbox Folder not displaying mail

The update (released today) for Mountain Lion, version 10.8.5, is supposed to, among other things:

  Fix an issue that may prevent Mail from displaying messages.

I'd be curious to see, since this issue was never solved, if this update resolves it.


Dual External Monitors on a (late) 2017 MacBook Pro

Your problem is that you have chosen a USB-C hub - this means that MST is a requirement for supporting dual displays in a non-mirrored configuration. MST is not supported on macOS, but will work if you run Windows.

In order to get dual displays working, you'll need to either: (a) connect each monitor seperately to the two Thunderbolt ports on the Mac - directly or through your hub, or (b) get a Thunderbolt 3 hub/dock with dual display capability.

Such a Thunderbolt 3 dock could be for example the OWC Thunderbolt 3 Dock. With that dock you would need to connect your two monitors to the dock like this:

Monitor A: Connected to mini-DisplayPort port
  Monitor B: Connected to daisy-chain Thunderbolt 3 port

Note that you'll need cables that match the inputs your monitors support. That could be for example a mini-DisplayPort to DisplayPort and a Thunderbolt 3/USB-C to HDMI cable.

The OWC dock is just one option - many other docks are available from various vendors at various price points.


How to trim many files using adobe photoshop

Another option using ImageMagick:

mogrify -trim *.png

You can install it with brew install imagemagick after installing Homebrew.


Connecting a VGA monitor via Thunderbolt to a MacBook Pro

Open System Preferences → Display.

Hold ⌥option which will change the ‘Gather Windows’ button to ‘Detect Displays’.

Clicking it might detect your VGA.


Can I set the iPhone to vibrate except for one contact?

Buy a 'silence' ringtone from the iTunes Store. Make this your default tone, except for that one person.


In Terminal type, man mount and press enter.

It says:

  The system maintains a list of currently mounted file systems. If no
  arguments are given to mount, this list is printed.

So, in Terminal type, mount and press enter.


In the Disk Utility app, Click the 'Partition' Toolbar button, then in the big pie chart in the revealed tab, click on the partition you want to erase, then click the minus button ('-') at the bottom of the chart. That partition will be deleted, and the other partition will be expanded to to include the newly-emptied space.

If you're doing this by command-line I think you can use the following (based on the diskutil output shown above):

diskutil mergePartitions JHFS+ "Macintosh HD" disk0s2 disk0s4

The third and fourth terms (JHFS+ "Macintosh HD") are actually dummy terms in this context; they are not used. Assuming that disk0s2 — the main partition — is in an expandable format, this should preserve everything in that partition and overwrite the other two. Per the diskutil man page:

  If force is not given, and the first partition has a resizable file
  system (e.g. JHFS+), the file system will be preserved  and grown in a
  data-preserving manner; your format and name parameters are ignored in
  this case. [If] the first partition is not resizable, you are prompted
  if you want to format.


Retrieve email error message on iphone 3gs

Since you did NOT specify the email type (server) lets use some generic methods to find out if the server is responding.
You can use something called

  Ping

an IP address or hostname in the Terminal for Mac OS X

What Ping does is it send a signal to the server (IP address) and check for respond. So if the server is alive it will respond. That will however not say if they have specific problem on the server.

To do that open your Terminal in Utilities.

Type:

  ping [-Options] ip or hostname

Usage: Ping's an IP-address or a hostname (which can be used to troubleshoot connection problems to another computer or a server).

Options

-c (num)    Stop after sending and receiving  number of packets.

-f  Flood ping: Flood ping, output packets as fast as they come back or 100 times per second.

-i     Wait for  seconds between sending each packet.

Example
ping 127.0.0.1  Ping your own computer (localhost)
ping -c 10 google.se    Ping google.se and stop after 10 sent and received packages.

Quick tip: If you're using ping and the response keeps coming in without stopping. Hold down "Ctrl" and hit "Z" (Ctrl+Z) to abort.


System Keychain Certs Import fail with UNIX[Operation not permitted]

The issue is that, somehow (not sure how), the extra restricted flag was add to System.keychain which meant it could not be modified while the system is running. Thus, it was SIP protected. I followed this guide to correct the issue.

(From the guide) You can check if your keychain is restricted using the following ls flags in the Terminal

cd /Library/Keychain
ls -@Oaen

My original output had the following info --- note the restricted flag on System.keychain.

To correct this, you have to boot into recovery mode. Hold down CMD-R during reboot when hear the chime. When there:

Open DiskUtility and check to make sure your main disk is mounted. It will not be if use FileVault to encrypt it. If not, mount it by entering your password. Quit DiskUtility.
Under Utilities menu, you can open a Terminal, change directory to keychain folder and edit the restrictions. (Note your volume name may be different if you have a non-standard installation.)

cd "/Volumes/Macintosh HD/Library/Keychains/"
chflags norestricted *

Check the ls -@Oaen and you should not see the restricted tag.
Exit Terminal and reboot.


Why are past purchases no longer showing after I change country of my Apple ID?

This is by design.

A developer lists an app for one or more markets and when you lose past purchases, that indicates that that app was available in the old market and no longer is available in the new market.

Have a look on the site, there are several threads on people deciding to switch countries or keep an old account.

One is simpler and potentially costs more, the other costs more time, but you keep access to all purchases, past, present and future on two accounts.

I want to change the country on my app store account and I am having some problems?
Restoring past purchases from different country
Do I need to repurchase apps if I moved countries?

Also - the related section to the right should have several more likely threads to help.


Are there any replacement keyboard apps?

Sorry, but currently, no. Jailbreaking is your only bet (I'd advise against this, though).

In terms of what you want, it sounds like you are describing something that iOS already does. When holding down on the keys, it "magnifies" the key that you are holding so you can see what you are typing. I should mention though that holding down on certain keys will show you options of the same letter with the accents on top. Ex: Holding down the "E" key will give you options such as "E", "È", "É", and "Ę".

Here is an example of the action described above, but with a different option

How to use Dropbox to share files in Finder by right click on Mac OS 10.8?

this might help:  https://twitter.com/Dropbox/status/228603324440657921

long story short.  Update dropbox is what they say.

worked for me, so should work for you :)


Can iTunes sync podcasts to an iPhone without removing unfinished podcasts?

This IS actually the case.

  What you should have a look at is the selection option that you have set.

For instance, if you ask to only sync the "3 most recent unplayed episodes", it might be that the one you are listening to will be replace on your iPhone by the newly released episodes that have been downloaded in iTunes. When the episode you haven't finished will be one of the 3 candidates to be synced (i.e. "when you have listened to all the newer episodes"), the listening will continue where you were the last time you listen to it.

EDIT after the EDIT of the Question :

Hm, ok, with this edit my answer is not right anymore BUT i think you should have a way have it work as you want. If you select for instance "the oldest unread", the one you are listening to will be kept on the iPhone (if you listen to the episodes in order that they are realeased) Another trick is to use the checkboxes on the left of each episode and set the preference to "Sync only checked"


Right speakers malfunction on MacBook Pro Retina

To isolate whether this is truly a hardware or software problem..

Launch /Applications/Utilities/Audio MIDI Setup.app
If it doesn't already show, select Audio Devices from the window menu
Select your Speaker output on the left Sidebar; the tab on the right should show Output highlighted & Input greyed out
Bottom right, select Configure Speakers…
In the new dialog that drops down you should see 'front left' & 'front right' each with a drop menu beneath.  The channels are likely just labelled 1 & 2.

Swap the channels - set left to 2 & right to 1.
Test with some audio playback.

If the right speaker still crackles - it's a hardware problem.

If the left speaker is now the one affected - it's a software problem.

Add a comment if it's software & we can test further.
If it's hardware, it's a trip to the Apple shop, I'm afraid.

Late Edit:
Because comments seem to be trying to break the laws of physics, let me explain further what is the most likely damage, & why it cannot be due to "magnetisation".
So, lets do a very quick 'physics 101' on the principles of loudspeakers.

The basic elements of a speaker are

a housing to keep all of the following in place.
a permanent magnet.
a coil of electrical wire [usually copper] on a hollow cylinder, placed to intersect that magnet & free to move, within tolerance, inside the magnet.
a cone of paper or plastic, fixed to the coil at one end & the housing at the other, used to project the sound from the coil into the room.

By definition, a permanent magnet is... permanent. Break it & both halves are still magnets. grind it to powder & every particle will still display the same characteristics. They are, for the purposes of this explanation, immutable.

As alternating current is passed through a coil of wire, it induces a magnetic field in the coil - positive & negative depending on the current flow, first one way then the other. As every schoolboy knows, opposite magnetic poles attract & similar poles repel.
The result of this is that the coil is forced first in one direction then the other in relation to the permanent magnet.
By having the coil connected to a larger cone, this transfers the movement into air pressure waves... sound.

The copper coil can never be permanently magnetised, because that can only happen [broadly] to ferrous metals - those which contain iron.

The most common ways to break this finely-balanced setup are :-

Stressing the join where the cone meets the housing - causing softening &/or eventual fracture at the join. This will make the speakers buzz at high volumes.
Overheating the coil until it permanently distorts. This will cause distortion at almost all volume levels.

Both of the above are usually caused by running the volume too loud for tolerance.
Over-compressed audio [Google 'The Loudness War' for background] or sound applications designed to 'make it all louder' (Boom, I'm looking right at you:/ ) will contribute to early failure.

A third, often overlooked cause is moisture. Paper cones & coil substrates don't like moisture.. whether it's just continuous high humidity or inelegantly-applied soda.

The tolerances between magnet & coil are measured in microns. Distort the coil or the cone & your speaker is as good as dead.

With an analog amplifier, running at low battery power would contribute by adding distortion to the signal at lower volumes. Computers don't really suffer from this, as their batteries are designed to give close to full output until recharge.


MacBook Air won't power on, except I remove the battery and plug it back in (SMC reset?) - sleep works

There are two possible causes these symptoms:

Faulty Battery
Bad SMC Chip (Logic Board)

Faulty Battery.  As the OP described, once the battery was disconnected, the machine booted fine.  What could be happening here is that the battery life has degraded to the point where it will not hold a charge above the threshold to power on the device.

If you can power the MBA in this manner, try resetting the SMC then reconnect the battery.  If it continues to fail, you probably need a new battery.  If you already know how to open the MBA and disconnect the battery, you are halfway to replacing it.  If you're not sure, ifixit.com has an excellent tutorial.

Given that the OP's machine is a 2012, it would mean the battery is pushing 5 years now which is around the EOL for this battery.  It's time for a replacement.  I recommend getting one with at least a 18 month warranty.

Faulty SMC.  There is a possibility that the SMC (chip) is faulty.  The first thing to attempt to diagnose it would be to run Apple Hardware Test (AHT).  Hold the D key while booting from a powered off state with the AC adapter connected.

It may come back with "no errors" so the positive diagnostic test would be to attempt with a known "good" battery.  If it continues to fail after the battery is replaced, there's a high chance than the SMC is bad.  It's time to take it in for service.


Is there a way to exclude certain apps from showing in the spotlight/alfred results

If you go to System Preferences > Spotlight > Privacy and click the [+] button to add an application they are grayed out and cannot be added in this method.
However, you can, instead of clicking the [+] button, simply drag and drop the application(s) from Finder onto the list area of the Privacy tab to have it removed from Spotlight searches.

Remote File and Application access from iMac to Macbook (Not screen sharing)

Hardware
You have two vastly different hardware platforms.  One (iMac) has twice the standard memory of the other (MacBook Pro) - 8GB versus 4GB and two generations and (approx) 30% difference in clock speed.  You're also developing UI on a 27 inch screen then switching to a 13" screen
There's no getting around this discrepancy in horsepower.
Software Licensing
This shouldn't be an issue on two computers.

XCode is free and you can install it on multiple computers that is associated with your developer ID

Adobe CC products can be installed and activated on two computers simultaneously, but you can only use one at a time.

Remote Work
If your work is 90% remote as in you live out of a suitcase, your best bet it is get the most powerful MacBook Pro you can afford and utilize external monitors (hotel TVs perhaps?).
If it's remote as in you work out of your house, your current setup is fine - you just need to move your data to the cloud (iCloud, OneDrive, etc.)  and sync the data and install the apps on each Mac.


Internet connectivity on 3g iPad when on a non-internet-connected wifi

When connected to both Wi-Fi and 3G, you have two IP addresses. One handed out by DHCP on your portable Wi-Fi network and one from AT&T (or Verizon, as may be the case).

To my knowledge and from my experience, your iPad will use the IP address obtained by Wi-Fi first, and then 3G. So if you're connected to a Wi-Fi network that doesn't have internet connectivity, the email address you're trying to check has nowhere to go since you don't have internet service connected to your portable Wi-Fi network.

Unfortunately, this means that in order to check your email, you'll have to disconnect from the portable Wi-Fi network, allowing the 3G IP address to become active.


Security Hardening Adobe Acrobat DC for macOS

I would start with one thing and that’s work on your time to patch in your environment. Measure how many endpoints are out of date and average time to get machines patched once Adobe releases an update (plan on 40 updates a year if you use the core CC suite - 15 if you just deploy acrobat).

You can control it.
It’s something one person can tackle.
It is your best defense to get ready to take next steps on how the quickly patched software is used.

If you don’t have federated ID services, get that next. Then look at Adobe Console to use SSO / federation and then decide if you just manage apps and lock everyone out of Adobe Updates and have a side channel for patching. JAMF and Munki and Fleetsmith (cough, Apple) are the three solutions I would evaluate if you know nothing about MDM. If you know everything about MDM - still evaluate them and then expand to include your current MDM or others that might fit your niche.
Security is a war of attrition and you will never have enough time to train, hire, manage but you can get better at evaluating your biggest gaps, work to close them and then repeat the observe, measure, plan, act, measure, react cycle.


ExFAT partition on External HDD not showing up on Bootcamp Windows 7

From the Tom's Hardware Forum:

  By default, the OSX disk utility creates a new partition as GUID. Windows can't read it. You need to create the partition type as MBR, which Windows can read. Then format as exFAT and both machines will read it.

Apple Numbers: how to change a date format to a number format

You can use a function to convert the duration to a plain number.  For example, if difference between the dates in in E4, and it's 10 days, then...

=DUR2HOURS(E4) × 0.1

Shows a number, 24.0. There are other functions that you might use: DUR2DAYS, etc.


Opening and Editing CorelDraw Files on MacOS Sierra

You can check out this free option: CDRViewer. It will allow you to open/view CorelDraw files.

For more advanced functionality, the same developers offer PrintLab Studio 3.

You can also visit the developer's direct website at: http://blue-tail.com

NOTE: I have no affiliation whatsoever with the developer or this product.

[EDIT]

Just thought I should add that Adobe Illustrator has always been capable of opening CorelDraw files. I mention this in case you already have access to Illustrator and didn't realise it supported this.

Can I use my iMac as a display with my MacBook?

Which model of iMac do you have? Only the latest 27-inch model supports video in physically. There are software solutions if you don't have this model.

I'm not sure if this is the latest solution (I expect not), but it was a software solution to this problem. http://www.rutemoeller.com/mp/ibook/ibook_e.html

I'm sure I've seen something more recent than this, but can't find a link to it unfortunately.

Update: Found the software I was thinking of, the developers site is here: http://www.screenrecycler.com/ScreenRecycler.html


Install Mavericks on second partition in Yosemite-only system?

You have to cheat the Mavericks Installer by running it on a "pre-Yosemite" system.
The system version is determined by the key "ProductVersion" and the associated string in the file SystemVersion.plist. Replacing the 10.10.x string with 10.9.x or 10.8.x will do the trick.

Beware: After manipulating said file you can't open most of the current apps anymore.

Prerequisites:

a current backup of your Mac
already downloaded OS X Mavericks Installer
a Mac capable of running Mavericks

Age your system:

Log-out any other user and log-in with your admin account.
Quit any running app and open the folder containing the Mavericks installer.
Open Terminal.app.
Make a backup copy of SystemVersion.plist first by entering:

sudo cp /System/Library/CoreServices/SystemVersion.plist /System/Library/CoreServices/SystemVersion.plist.backup

and hit ↵
enter your admin password and hit ↵ (the password won't be visible!)
Modify SystemVersion.plist:

sudo nano /System/Library/CoreServices/SystemVersion.plist

change the both strings 10.10.1 (or 10.10.0) to 10.8.1 or 10.8.0

write the changes to disk with ctrlO followed by ↵
and exit nano with ctrlx
Recheck the successful change by entering:

cat /System/Library/CoreServices/SystemVersion.plist

Enter exit, hit ↵ and quit Terminal.app.
Start Install OS X Mavericks and choose your already created second partition to install to. You may have to click "Show all partitions" if your second partition isn't visible initially.
After installation and configuration of Mavericks is finished revert the changes of SystemVersion.plist on the Yosemite partition:

Rejuvenate the Yosemite system:

Open Terminal.app in your Mavericks admin account and enter:

sudo rm /Volumes/NameOfYourYosemitePartition/System/Library/CoreServices/SystemVersion.plist

and hit ↵
enter your admin password and hit ↵ (the password won't be visible!)

then enter

sudo mv /Volumes/NameOfYourYosemitePartition/System/Library/CoreServices/SystemVersion.plist.backup /Volumes/NameOfYourYosemitePartition/System/Library/CoreServices/SystemVersion.plist

and hit ↵
Enter exit, hit ↵ and quit Terminal.app.

If the install fails and you are urged to boot to Yosemite (which probably fails), try to boot to Recovery Mode or Internet Recovery Mode, revert the changes of the file SystemVersion.plist on the Yosemite volume from the command line in the same manner as described for the successful Mavericks install in step 10.
Then restart from scratch.

(Tested in a Yosemite VM...works)


Command-W not working correctly on Safari

Go to your System Preferences… application, and select the Keyboard pane.

Hit the Keyboard Shortcuts tab on top, and Application Shortcuts on the left. Is there an entry for Close Tab ⌘W or an entry for Close Window that's set to something else? If so, remove it with the +- widgets at the bottom of the window.

Without knowing what other applications you're running, that's the first place I can think of to check what might be intercepting it.

OS X Installation USB not detected in Startup Disk selection

In order to boot from an external disk it must have a GUID Partition Map. If your USB disk is not formatted with that you will need to reformat it accordingly.

Go to Disk Utility

Using Windows on Mac keyboard without Delete key

When you press the Fn key, the backspace key (Mis-labeled "Delete") on a mac keyboard functions as the delete key.

Therefore, to log onto a windows install which requires Ctrl+Alt+Delete, you would press Ctrl+Alt+Fn+Backspace("Delete").

It's worth noting that this works even on the full wired keyboard, with a separate delete key.


Does upgrading to Mountain Lion means I have to reinstall Android SDK and Eclipse?

No, nothing is deleted when updating. A common sense would be to back-up everything as things can go wrong, but if everything go right, nothing is deleted! Even opened apps are reopened after update.

It must be noted though that the first time you launch Eclipse, OS X will tell you that it will install Java first, as Java is not installed by default anymore.


Why does streaming audio in Mobile Safari sometimes not have a scrubber bar?

The difference should be a static file with a defined content length, vs. a shoutcast stream or a server that did not serve a content length with a file.

If the player does not know how large a file is, it cannot retrieve the end to gather metadata (notably, song duration), and present the scrubber for seeking.

On the latter file (via flex), I notice a lack of "Accept-Ranges", and a "Connection" type of "keep-alive".

This tells me that;
(1) that Safari (/QuickTime?) likely will not issue a byte range request for the end of the file in order to read the ID3 data, or;
(2) There is no scrubber because "Connection: keep-alive" means that new data may come down the pipe, so keep the socket open to receive it at some time.


How to start an application when a specific disk is mounted

I didn't downvote wch1zpink's answer, but it's very much not the way that I would solve the problem.

Having an app run an AppleScript every 5 seconds is a very inefficient way to handle this situation, especially since Mac OS already has a built-in feature to do this, namely, launchd.

Save this as ~/Library/LaunchAgents/com.tjluoma.itunes-on-mount.plist (you can change the "com.tjluoma.itunes-on-mount" part to whatever you want):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.tjluoma.itunes-on-mount</string>
    <key>ProgramArguments</key>
    <array>
        <string>/bin/bash</string>
        <string>-c</string>
        <string>test -d /Volumes/Media &amp;&amp; open -j -g -a iTunes</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>WatchPaths</key>
    <array>
        <string>/Volumes</string>
    </array>
</dict>
</plist>

Then either reboot your Mac or do

launchctl load ~/Library/LaunchAgents/com.tjluoma.itunes-on-mount.plist

in Terminal. Then, anytime /Volumes/ changes, launchd will look to see if /Volumes/Media exists, and if it does, it will launch iTunes.


Mail cannot connect to google account, won't open once quit

I had this problem yesterday and restarting seemed to fix the issue. When it came back today I looked online but couldn't find any answers. A look in the console showed that the issue was not network related, but actually caused by low disk space. Sure enough, making some space on my drive ( . . .was down to the bytes) immediately fixed the issue.

Moral of the story: Keep your disk clean!


deleting single entry from history in zsh -- Terminal

You can either use:

open $HISTFILE && exit

which usually opens TextEdit (or another default text editor - depends on your environment) and remove the line (and the last temporary line containing something like : 1583100426:0;open $HISTFILE && exit) and save the file ("Save Anyway").

or - if you know some exclusive content of the line (in my example below PASSWORD):

setopt HIST_IGNORE_SPACE
 LC_ALL=C sed -i '' '/PASSWORD/d' $HISTFILE

the first command sets the option to not add commands prepended by spaces in the history file
the second command (prepended by a space!) removes all lines containing PASSWORD from the history file

Both commands won't remove unwanted lines in zsh history files in e.g. Time Machine backups!


Sync Chrome passwords with Apple iCloud Keychain

I've created small tool to deliver your credentials from Chrome into macOS keychain. Here is a page on github https://github.com/nntarasov/csv2keychain

The program interacts with macOS command-line utility called security with option add-internet-password. First of all you have to manually export credetials from chrome into .csv file. There is such feature in Chrome. So, the idea is very simple - the list of credentials from file is being added into system keychain via security


Keep iCloud Drive directory for "offline" use on iPad?

I do not think there is an "Keep Offline" feature on iCloud. I generally hit the download icon next to the files that I would need before I travel. But on iOS13 there is a new pin feature for folders that would keep the folder for offline access.


Sending text to an open terminal window with automator

OK, I created an AppleScript inside automator that did the trick:

tell application "Terminal"
    set currentTab to do script ("ssh me@10.0.1.25;") in front window
end tell


iOS: Does disabling Safari restrict all web browsers?

It does not restrict other browsers, you would have to set controls on the app store to prevent the download of 3rd party browsers.


Cannot repair permissions on systemsetup (open error 1)

It's possible that this is a message that you can safely ignore.

There is an Apple KB article for OSX versions 10.6 and below that itemises those error messages that can be ignored, however that message is not in the list.  I cannot find an updated KB article for 10.7.

If the message does concern you, I'd suggest you reboot and hold down the Option key, you can then enter into Lion's Recovery mode from the menu shown and see if that does the trick.


Try to edit the .profile or .bash_rc file on the terminal

 /usr/bin/vi ~/.profile

and see if one of the software has put stuff in there that should not be there (especially if one has put up a messed PATH command there).  (Alternately but less likely affected are  /usr/bin/sudo /usr/bin/vi /etc/profile or /usr/bin/sudo /usr/bin/vi /etc/bashrc).

If you don't know how to use the VI editor, you can also use /usr/bin/nano instead of /usr/bin/vi

For a start, until you find where this happens, editing the .profile (see above) you can put the following command as the last command to the end of your ~/.profile file.

export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

This should at least give you back access to your normal commands.


How to avoid qtvr files being transformed to movies

QuickTime VR hasn't been used for at least 10 or 11 years so it's going to be really difficult to find a current player for this file format.  There's likely no path to remedy this.

Even on Apple's website, it's listed as "legacy/historical".  This piece of documentation was updated in 2009 - 8 long years ago.

From a 2016 Business Insider Article:  The inside story of Apple's forgotten project to change how we explore the world from our computers

  When Steve Jobs returned to Apple, QuickTime VR was de-emphasized. Apple put out its last QuickTime VR-specific press release in 1997, although Apple continued to use it to provide 360-degree views of new products like iPods as late as 2006. "Quicktime VR all really happened in that Scully window before Steve came back, and I think that Apple does not pay any attention to the stuff that happened during those years," Bohrman said.

There may be some open source or 3rd party applications that support it, but going off Wikipedia, the list is quite small.


Macbookpro can't recognize bootable usb at boot time?

rEFIt is a useful utility for selecting boot partitions that don't necessarily show up normally (Linux bootloaders, incomplete installs for example, or if there is something out of sync with the boot sectors).

You could use it here to see if it can recognise your USB stick, you could also use it to boot Windows from FireWire if that's at all useful.

You'll need a second usb stick to run it in 'live boot' mode, if you don't want to have it installed on your system, but it's pretty small so even 20MB is enough. Download the disk image and use Disk Utility to clone it onto your second usb stick, then boot with option held and it will appear.


Right-click on the column headings and select Artist to add the column back.

Going to System Preferences > Security & Privacy > Privacy > Diagnostics & Usage and unchecking Send diagnostic & usage data to Apple did not work for me. I still get the Little Snitch dialog asking for permission to connect to radarsubmissions.apple.com.

It seems the connection attempt is triggered by a launchd job located at /System/Library/LaunchDaemons/com.apple.DiagnosticReportCleanUp.plist. On Mountain Lion 10.8.4, it's set up to run every day at 11 am. If I clear the Little Snitch rules for the SubmitDiagInfo process and run the following command to start the launchd job sudo launchctl start com.apple.DiagnosticReportCleanUp, the Little Snitch connection dialog pops up.

This seems to be a bug as the DiagnosticReportCleanUp job is not respecting the Privacy setting in System Preferences. I've denied the connection attempt Forever in Little Snitch for now. Hopefully, this gets fixed in OS X 10.9 Mavericks.


Here is the same program, as a perl one-liner, which works (tested) on Mac, Linux, and Windows

}' | ./play -c 1 -b 8 -e unsigned -t raw -r 8k -

the "./play" command is the "sox" utility already mentioned in this article.


How can I ensure TRIM is enabled when installing Yosemite onto an SSD drive?

If you're running OS X on a HDD then I don't see how TRIM enters the equation, since TRIM is only for SSDs. If want to do a fresh install on the SSD, simply install it and proceed with your bootable USB, I do not see the problem.

What I did when installing the SSD was to put it in an enclosure, connect it via USB and  use Carbon Copy Cloner to clone the OS and some other stuff to the SSD, while leaving the big data (movies, music, etc.) on the HDD (which I then put in the optical bay). If you want to have certain parts of you user data on the HDD, you can create a symlink for that.

If you do not insist on a fresh install of OS X this is the way to go in my opinion.

EDIT:
A word on TRIM:

The issue with TRIM on OSX is that it is supported only for SSD installed by Apple themselves. So to enable TRIM on third-party SSDs, one needs the Trim Enabler app which does it for you. All was fine until the release of Yosemite. The Trim Enabler App uses a so-called kernel extension or kext (I think this is more or less the same thing as a driver, but I'm not sure). With Yosemite, Apple introduced kext signing which means no kernel extensions will be loaded which are not signed (which can be done only by Apple). Now the developer of Trim Enabler has no way to get his extension signed (Apple would not do that because if they did, no one had to buy SSDs from Apple to get TRIM, a policy which I find appalling).

The problem is that if you have TRIM enabled with the app and then try to boot a computer with kext signing enabled, it will refuse to boot since the TRIM extension is not signed. That makes it necessary to boot to recovery mode and disable kext signing from a command line.

So the only workaround is to disable kext signing altogether. This is a global setting, so it will apply to all possible kernel extensions which means you must be extra careful when installing drivers (which you probably never do on OS X) because it can't be verified they are trusted by Apple. But since the signing mechanism was only introduced in Yosemite, having it disabled does not put you more at risk than you were on Mavericks or before that.

The status of kext signing is saved in NVRAM, which can be reset accidentally (or manually). If reset, it will default to kext signing enabled and thus you will be unable to boot and must take the steps already outlined.
Whatever you do, as long as you are able to boot into recovery mode, no permanent damage will arise from enabling TRIM.
But if you are not comfortable with the thought of having to go to recovery and type terminal commands, I would just stop worrying about TRIM and not use it, at the expense of some longevity and performance of your SSD.

All information on TRIM in conjunction with Yosemite is here. I do not know how this applies to you since you're on a HDD, but assuming that you have an SSD running with TRIM enabled through Trim Enabler, you should disable it before upgrading.

I forgot to do that. What happened was that the installer ran successfully and I even got to the desktop afterwards, only after rebooting did the problem occur (grey stop sign at boot). I had no secondary computer to look up the commands listed in 2, but if you do, you can simply boot into recovery mode (hold CMD-R at boot) (either from your backup - which I hope you have - or from the Recovery HD if present, or the internet-based recovery), which will then allow you to open a terminal, run the commands, shut down and all will be working as kext signing will be disabled. You can then boot normally and choose to disable TRIM if you are uncomfortable with kext signing disabled (I see no reason to, since it did not exist before Yosemite) or just continue to use it.


protecting keychain data when using Time Machine

Keychain files are password protected, your login password is required to access their content. In the file itself only passwords and the content of secure notes are encrypted so a potential attacker could at least read the URLs and the associated login names for web accounts etc.

For details about Keychain see Wikipeda and the pages referenced from there.


(SOLVED) - Error: "The device does not have the necessary services" when using bluetooth to browse files on Galaxy S7 Edge

Even if it should be part of the Android OS, looks like the OBEX FTP service is not included.
I searched the Play Store and there is at least one program that allows for browsing from a paired device (in this case my Mac) and it's: Bluetooth File Transfer (that also works as a client).
Remember to go into the app settings to select which folder will be used as a root for the server, otherwise it's set to /store/emulated/0


Whenever I open the Mac Terminal it shows "no such files or directory"

Whenever you open terminal some scripts are automatically called.

Programs (and users) add different commands to those files to set up their environment.

In default OS X configuration you are running a Bash shell which might run the following scripts:

~/.bash_profile (most probable)
~/.bashrc
/etc/bashrc
other can also be included from the above

You need to check (display for example with command cat ~/.bash_profile) each of them and search for the string USERNAME that is in the error message.

The next step depends solely on the content of the file. You might remove the offending lines or (safer) comment them out (putting # in front of the line).


Where is the backtick on iPhone keyboard

Switch from ABC to 123 & then press & hold apostrophe.
Backtick will be the left-most option in the pop-up.

I surprised myself by being able to actually screenshot it…


Game audio is tied to the ringer switch. Is this a bug or a feature?

This is intended behaviour as per Apple Guidelines.
From the Apple iOS Human Interface Guidelines:

Users switch their devices to silent when they want to:

Avoid being interrupted by unexpected sounds, such as phone ringtones and incoming message sounds
Avoid hearing sounds that are the byproducts of user actions, such as keyboard or other feedback sounds, incidental sounds, or app startup sounds
Avoid hearing game sounds that are not essential to using the game, such as sound effects and soundtracks

Specifically for games:

Scenario 3: A game that allows users to guide a character through different tasks. You provide:

Various gameplay sound effects
A musical soundtrack

In this app, sound greatly enhances the user experience, but isn’t essential to the main task. Also, users are likely to appreciate being able to play the game silently or while listening to songs in their music library instead of to the game soundtrack.

Deeper in the Audio Guidelines per App Type, Apple recommends use of the AVAudioSessionCategoryAmbient or AVAudioSessionCategorySoloAmbient categories, which are defined as:

AVAudioSessionCategoryAmbient/AVAudioSessionCategorySoloAmbient
[...]
Your audio is silenced by screen locking and by the Silent switch (called the Ring/Silent switch on iPhone).

Accordingly, for playback type apps, the recommended category is AVAudioSessionCategoryPlayback, defined as such:

AVAudioSessionCategoryPlayback
[...]
The category for playing recorded music or other sounds that are central to the successful use of your app.
When using this category, your app audio continues with the Silent switch set to silent or when the screen locks.

As long as the developers follow the guidelines, this is the expected behaviour unless Apple decides to change how the categories function in the operating system.


"Alert when I need to leave" reminds me 15 minutes too early. How can I turn that off?

I think here is the answer,

  When you create the event, make sure that you enter the location of the meeting in the event. Like in image, where you can see the greyed out portion with a caption

 2.

  Add Location (let it get recognize the event through the map app in
  the background -- you do not have to do anything, this will happen
  automatically based on your internet speed, so just give it some time,
  and once you the location listed, select the desired location from the
  options or the nearby location.)

3.

  Once you do that, if you try to set your event time say
  08:00PM-09:00PM.  Automatically you calendar will recognize this event
  as a remote location and will prompt you differently like this,

This will update you about the meeting at the right time accounting for your traffic and weather conditions.

Good Luck !


Safari asks for Flash to be enabled for every website?

Go to Safari Preferences, Security tab, and click Plug-In Settings. Select Flash Player on the left, and ensure that "when visiting other websites" is set to Off, rather than Ask.


As is not available on Apple websites, I found this that seems to work.

Visit this Softpedia link to download a free trial of iWork ’09.
Click Download, and then click External Mirror 1.
Double-click on the downloaded file. This will open up a window with a couple of files inside.
Double-click Install iWork ’09 Trial and follow the installation instructions.
After installation, close out the install windows and wait a few minutes for your Mac to recognize the newly-installed apps.
Next, open up the App Store app and click on the Updates tab at the top. You should see updates for Pages, Numbers and Keynote.
If you don’t see updates for these apps yet, close out of the App Store and wait a few minutes before opening it back up.


Easy way to get *all* Notes to synchronize via iCloud?

You need a 10.6/10.7 system handy as this doesn't work in 10.8. The method I've previously used is as follows:

Plug your iPhone into your Mac and go into iTunes -> Your Device -> Info tab and choose to Sync notes.
This should grab the notes out of the On my iPhone section and dump them into Mail.app.
Your notes should appear under the Notes section in Mail.app, but ideally filed under an On My Mac header.
Simply select all the notes from under On My Mac and drag them into the iCloud section. That should upload them all to iCloud and save you some time copying and pasting or fiddling with other software!


How do I automatically reconnect to wifi when the connection is lost?

While this doesn't solve your problem immediately, I can say that I had the exact same issue with my iMac and OS X 10.6. My solution? Get a new router. From that point on, the wireless connection was far more stable, and while the issue itself exists (say I make a lot of changes in the router that requires the connection to drop -- my iMac won't always reconnect), the router itself seems to make a big deal in the connectivity. (I went after one of the newer N routers; my previous router was a G router.)

Other things to try (before shelling out $$$):

Make sure your router's firmware is up-to-date (Mine was, unfortunately)
See if you can install a custom firmware (like DD-WRT) that might solve the problem (this is really dependent upon router type, so not all routers are supported)


Can a Mac's model year be determined with a Terminal Command?

You can indirectly get this information from a web page and the curl command. In the past this URL has been taken down and rate limited and put behind some sort of captcha to prevent this use, so you might need to resort to other avenues like https://checkcoverage.apple.com/ in that case.

Depending on if your serial numer is 11 or 12 characters long take the last 3 or 4 characters, respectively, and feed that to the following URL after the ?cc=XXXX part. If your serial number was 12 character and ended in DJWR, you would issue this command:

curl https://support-sp.apple.com/sp/product?cc=DJWR

To get your serial number, use the following command:

system_profiler SPHardwareDataType | awk '/Serial/ {print $4}'

Thus, you could have a complicated command to query the internet if you need a single command:

curl https://support-sp.apple.com/sp/product?cc=$(
  system_profiler SPHardwareDataType \
    | awk '/Serial/ {print $4}' \
    | cut -c 9-
)

and then run the output of that through sed to cut to the key part

curl -s https://support-sp.apple.com/sp/product?cc=$(
  system_profiler SPHardwareDataType \
    | awk '/Serial/ {print $4}' \
    | cut -c 9-
) | sed 's|.*<configCode>\(.*\)</configCode>.*|\1|'

There used to be a private library file with these mappings so you could consult it offline, but I noticed it was gone as of 10.8.3 (and perhaps earlier) so the above trick is the only one I know that works on the current OS without third party libraries.

Some nice third party libararies provide a look up of this:

python code https://github.com/MagerValp/MacModelShelf
JSON mapping https://github.com/krypted/swiftwarrantylookup/blob/master/src/swiftMacWarranty/model_snippets.json

Note that as of November 2017, Apple has forced the use of https over http for this service.

Is Yosemite Mail caching signature files? How can I get around that?

I had the same problem as you. I did some digging around and found a solution that used to work back in the OSX 10.8 days and stopped working with OSX 10.9. Oddly enough, it works again with OSX 10.10.1 and Mail 8.1 (1993).

There are multiple parts to this - an AppleScript that you compile into an Application, a text file containing your random quotes, two signatures in Mail.app (one is a template, the other is the actual signature for your messages), and the system 'cron' service. (Ideally you should use launchd, but I haven't got that far yet.)

The AppleScript:

if application "Mail" is running then
    set AppleScript's text item delimiters to "~###~"
    set myQuote to some text item of (read "/Users/Steve/.sigs.in")
    tell application "Mail"
       set the content of signature "MySignature" to the content of signature "MyTemplate" & myQuote
    end tell
end if

In my implementation (which you can deduce from the AppleScript):

My two Mail.app signatures are called "MyTemplate" and "MySignature".
"MyTemplate" contains everything that is static - stuff like my email
address, etc. "MySignature" is the one that I use with my messages.
The text file holding my quotes is called ".sigs.in"
(so that it doesn't appear in Finder windows) and all the quotes are
separated by a line holding only "~###~". This file lives in my home directory.
My crontab entry consists
of * * * * * /Users/Steve/bin/MailRandomSig.app/Contents/MacOS/applet

The compiled AppleScript lives in /Users/Steve/bin (obviously enough), and the "applet" part is the actual compiled binary that we want to run.

I've tested this and it works beautifully. Each minute, cron kicks off my compiled script which updates the signature.

The only "downside" is that if you don't like the quote you have to wait a minute for the script to refresh the signature and then reselect the signature from the drop-down selector in the message composition window. (I have two signatures - one static, the other the output of my script - to get around this.)


nvram -p shows "LocationServicesEnabled %01" ... does that mean I have a GPS?

Location services do not mean your computer has GPS capabilities but that it is using information that individuals provide, also google or other mapping servicing discover information from wifi broadcasts. Below is Apples take,

Your approximate location is determined using information from local Wi-Fi networks, and is collected by Location Services in a manner that doesn’t personally identify you.

If you allow third-party applications or websites to use your current location, you are subject to their terms and privacy policy and practices. You should review the application’s or website’s terms, privacy policy and practices to understand how they use your location and other information.  Information collected by Apple will be treated in accordance with Apple’s Privacy Policy, which can be found at www.apple.com/privacy.

My take,
This can be fairly accurate as long as no one moves their wifi modem. For an example if an entire neighborhood moved two hundred miles away and did not change any settings (and were not remapped) ones computer would think it was in the original location.


How can I reinstall Lion so that the "Welcome" movie plays at first boot?

You can't — sadly, Lion has no welcome video!

(However, you can reset a machine to the first-boot state by simply booting from the recovery partition, erasing the drive, and reinstalling Lion. See this thread for more instructions.)


Slightly offtopic, but maybe useful if you want to stick to putting credentials with special chars in a Shell variable.
Regarding your bash commands I will point you to several topics:

PWD is a always present ENV variable showing the current working
directory (Print Working Directory). Omit using that name for a PassWorD variable :-).
There is a significant difference in using double quotes and single
quotes. Double quotes embrace a string, which also can contain expandable variable names and is always subject to escape problems. Single quotes define a fix string and will be treated as such, e.g. no variable expansion will be done.

Example:

# fix string
tatooine-2257:~ mallert$ export P='<word'
tatooine-2257:~ mallert$ echo $P
<word
# no variable expansion
tatooine-2257:~ mallert$ export P='<word $PWD'
tatooine-2257:~ mallert$ echo $P
<word $PWD
tatooine-2257:tmp mallert$ echo $PWD
/tmp

Finally - treat variable names in expansion distinguishable from usual text like referring to ${variablename}. (Bourne Shell style)
Try open 'smb://username:password@server/share' - it creates the volume mount for you. If you omit the password, Finder will ask you for it.


Loading bar stuck at the very end after entering login credentials

I have fixed the issue.  It manifested after the installation of a driver with an unsigned .kext file.  In this instance, it was from this driver (Roland DJ-202 DRIVER VER.1.0.3).

At the time I didn't think this was causing the issue because this driver was installed and ran fine on a friend's MacBook Pro running on Mojave. The difference was that his machine is running 10.14.3 and mine is running 10.14.6. It seems that this driver does not work on macOS Mojave 10.14.6.

I discovered the issue after reading through this. After moving all the .kext files to an unsupported folder (see below) I was able to boot successfully boot the machine in safe mode and normal mode.

mount -rw /
cd /Volumes/Macintosh\ HD/Library/Extensions/
mkdir Unsupported
mv *.kext Unsupported
reboot

After reading through this I was able to identify the .kext files that are properly signed by Apple. They are the following

ACS6x.kext                CIJUSBLoad.kext
ATTOCelerityFC8.kext      CalDigitHDProDrv.kext
ATTOExpressSASHBA2.kext   HighPointIOP.kext
ATTOExpressSASRAID2.kext  HighPointRR.kext
ArcMSR.kext               PromiseSTEX.kext
BJUSBLoad.kext            SoftRAID.kext

I then identified the culprit file from the driver - RDUSB0205Dev.kext.
I moved all the other .kext files back into the /Volumes/Macintosh\ HD/Library/Extensions/ folder.

The machine now boots fine, and everything is back to normal.


Cannot erase disc in disc utility before trade in

The Base System (& the potential 20 or so tiny volumes you may be able to see below that) are part of your current Recovery session. You cannot erase them - nor do you need to. They are ephemeral & will disappear once you again boot to a normal OS.
You install your new OS to the main drive, once it has been erased.


You can't restrict Messages by person/number.  You can only turn Messages off or on.  This site can show you how to do that while using Restrictions to prevent your daughter from making changes.

There are some 3rd-party applications that might be able to do what you want.  Search the App Store for messaging apps that have that feature.


Time Capsule - what happens when full, if there is more than one system backup?

Space will be reclaimed by Time Machine only using the older content from backups of the same computer. Consult this archived page from Pondini:

  Time Machine will, eventually, fill all the empty space available to it before it begins deleting old backups.  When multiple Macs are "competing" for the same backup space, there might be room for several months of backups for one, but only a few weeks for another.  This is especially likely to happen if you start backing-up a new Mac to a drive that already has a lot of backups from another Mac.  Time Machine on the new Mac will not delete backups from the other Mac(s), so when it needs space for new backups, it will delete the oldest backups from the new Mac instead.

With a Time Capsule or any network drive used as a disk for Time Machine, every computer backup is stored in its own sparse bundle disk image. This is how multiple computers can be backed up to one location. Within each sparse bundle disk image, linking is used to minimize the storage required for files or folders which have not changed between backups.

This archived page from Pondini explains how to manually delete from backups and also explains the structure.


Upload file directly from a URL in upload (File/Open) dialog

The Go To Folder command you mention (command-shift-G) will only navigate your locally mounted volumes, it doesn't understand URLs.  I've never seen anything on the Mac that has the function you specify..


It is now possible to emulate PowerPC for Mac OS 9.2.2 through 10.5 via QEMU: https://wiki.qemu.org/Documentation/GuestOperatingSystems/MacOS10.4 and https://wiki.qemu.org/Documentation/Platforms/PowerPC.

You'll need to install homebrew, a package manager for Mac OS X/OS X/macOS. Then run brew install qemu (which already contains the PowerPC part).

To create the a hard disk image, run

qemu-img create -f qcow2 example.img 100M

replacing

example.img with the path you want to store your disk image in
100M with the size you want (at least 3.0GB to install Tiger according to Apple, probably about 10GB to be safe).

You could also use a sparse (bundle) disk image with QEMU (you'll then be able to natively mount it within the host) but that requires a bit of setup and a script.

You can run then Tiger with

qemu-system-ppc -L pc-bios -boot d -M mac99 -m 512 -hda example.img \
    -cdrom <iso file of installation media> \
    -netdev user,id=mynet0 -device sungem,netdev=mynet0 `

where  is the ISO of a Tiger install disk (you could also use the disk directly as well as dmg images using the same method for a sparsebundle)


Does gatekeeper not check apps stored in /Applications/?

If I remember correctly executables are only checked by Gatekeeper if they have the quarantine filesystem attribute attached. And the quarantine filesystem attribute is (optionally) added by applications which download files from the internet.

So if Gatekeeper is not checking files it could be because the quarantine attribute has already been removed (after a successful check) or because they were downloading using an application that doesn't apply them in the first place (for example I think some torrent applications don't apply them, whereas most if not all web browsers do).

For example I just downloaded Firefox using the Safari web browser so if I run ls -l@ Firefox\ 54.0.1.dmg to show any attached file system attributes I get the following, which includes the quarantine tag...

-rw-r--r--@ 1 alistair  staff  59438170  7 Jul 00:23 Firefox 54.0.1.dmg
    com.apple.metadata:kMDItemDownloadedDate          53
    com.apple.metadata:kMDItemWhereFroms         203
    com.apple.quarantine          61

This is why you see people suggesting removing the quarantine tag as a way to get around the Gatekeeper security prompts.

It said I needed to update my account security and prompted me with a few security questions. This seems to have indirectly solved the problem; perhaps some minimum standard of security was not upheld and was causing quiet failure.

Unfortunately, I'm guessing that this won't solve everyone's problems as it seems to be a pretty generic message as mentioned above, just thought I'd add my solution to the pile for everyone who's going down the list and trying everything.


how to permanently enable night shift in Mac OSX Sierra?

I just use the schedule with the following custom schedule:

From: 04 AM

To: 03:59 AM

This way it's always on (apart from that minute between).

Note: I don't know if this will work with all external monitors; in which case as suggested you will have to adjust colour profile.


Is it OK to install one Office 2019 license on both Mac and Windows?

No.

According to Microsoft's Office product page, it is a one time purchase for 1 Mac or PC

This means that you can only install it on 1 machine - either a Mac or a PC, but not both.

There's also an excellent comparison chart showing what's covered between the 2019 standalone version and the O365 subscriptions.  As for number of devices, only the O365 subscriptions allow for multiple device installations.


TextEdit Chinese Plain Text Style Problems

I have so far only found one font which has all the characters -- Babelstone Han.   Try downloading that and switching the whole text to it.

Another possibility may be the MingLiu series of fonts that come with Word.

Of course plain text does not contain font info, so you are at the mercy of the the app and the OS regarding the fonts chosen, which will never be Babelstone Han unless this is installed and stipulated via rich text. In plain text I think you will always be stuck with two fonts which are unlikely to be identical in their display.

I notice, however, that your text above seems very even as displayed in my Safari.  I wonder what font it is using.


CPU Die temperatures reaches 90° C, is that normal?

The MacBook Air 13", Mid 2011, comes with an Intel Core i5 or Core i7 (2557M, 2677M) ("Sandy Bridge") Processor and the maximum temperature allowed at the die is 100° C, per Intel's documentation on both processors.  (See TJUNCTION in the links provided.)

So while you have not yet max it out, nonetheless it shouldn't be running that hot except under considerable load. If you'er seeing that high of a temperature under an idle load then it is something to worry about.


The answer to this is surprisingly simple:

$ osacompile -o output.app input.applescript

This works for both plaintext .applescript files and the .scpt files that Script Editor makes.

You can use a pipe too, e.g. if you have the script on your clipboard:

$ pbpaste | osacompile -o output.app

Or -e, like the osascript command can use:

$ osacompile -o output.app -e "$(pbpaste)"

You can also use JavaScript with the -l flag:

$ osacompile -o output.app -l JavaScript -e 'app = Application.currentApplication();' -e 'app.includeStandardAdditions = true;' -e 'app.displayDialog("hi");'
