How to install coqide (or such) with brew

The same bug (in the existing released binary) is reported here:

http://www.lix.polytechnique.fr/coq/bugs/show_bug.cgi?id=3155

and in the comments a link to recent builds is given:

http://www.pps.univ-paris-diderot.fr/~pboutill/coq-night/v8.4/

I don't know about stability, but 8.4pl4 appears to be working on Mavericks. I was able to build/install following README instructions (might additionally require install of OCaml and other tools, which I happened to already have.) The associated coqide also appears to be working without trouble.

I am not a seasoned Coq user, so if there are any functionality or stability considerations in this non-published version, then they would be going far over my head.


Add minor OS X update to existing El Capitan bootable Install USB

The probably easiest solution is to simply download the latest OS X El Capitan installer after a minor update was released. Usually the newest installer available in the App Store already includes the update.

To get the build version of the OS installed by the OS X installer.app enter in Terminal.app:

cat /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Info.plist | grep -A 1 BuildMachineOSBuild

The output

15A... usually indicates a 10.11.0 build
15B... usually indicates a 10.11.1 build
15C... usually indicates a 10.11.2 build

and so on. The build version here is not identical with the build version of the later installed operating system. To get that one you have to mount the InstallESD.dmg in "/Applications/Install OS X El Capitan.app/Contents/SharedSupport/". Then cd to "/Volumes/OS X Install ESD" and enter "open BaseSystem.dmg".

To get the Build or System version then enter:

cat /Volumes/OS\ X\ Base\ System/System/Library/CoreServices/SystemVersion.plist | grep -A 1 ProductBuildVersion

or

cat /Volumes/OS\ X\ Base\ System/System/Library/CoreServices/SystemVersion.plist | grep -A 1 ProductVersion

With the new OS X installer you can create a new bootable USB.

Depending on your internet connection that's probably faster and less hassle/error-prone than merging an update in an older full installer.


Unfortunate deleting binary command file

This question probably has all the answers for you. In short there is no easy way. Your options are:

Recover the files from a (Time machin) Backup, if existent.
Reinstall OSX, e.g. from the Recovery mode pressing  Command+R at the startup screen
Copy the missing files from the Recovery partition (check if the partition is up to date first). E.g. by doing cp -a /bin /Volumes/<your disk name>


How can I disable the trackpad when my mouse is plugged in on Lion?

Thankfully, you can still disable the trackpad in OS X Lion.

Open System Preferences, click on Universal Access, select Mouse & Trackpad and click on Trackpad Options... at the bottom. Tick the checkbox "Ignore built-in trackpad when mouse or wireless trackpad is present".

You can erase free space using Disk Utility. (/Applications/Utilities/Disk Utility.app).

In the sidebar of Disk Utility, select “Macintosh HD” (or the drive where you’d originally stored the file). At the top of the window, select the “Erase” tab. Towards the lower left-hand corner of the window, there’s a button labelled Erase Free Space. This lets you overwrite all of the free space on the drive (which is where your deleted file currently resides). You can choose a one-pass, three-pass or seven-pass erase — hopefully that’s more than enough. And if not, I guess you can just do it multiple times.

As always with Disk Utility stuff, be a little careful. I did this a couple of years ago with a three-pass erase, something screwed up and I had to restore from a backup :(


Why does iPad Video App Not Group TV Shows Correctly?

It's all about the metadata ‚ the track information stored in each media file.

A while back I had this problem with TV Shows ripped from DVD not displaying correctly, or not in the proper sort order, on my iPad. When I compared the metadata for my home-brewed files with those from files of episodes purchased from the the iTunes store, I discovered some differences. The solution that worked for me was to correct the metadata using the info pane for the media files in iTunes.

To get started, open iTunes, select one of the TV episode files that's giving you problems, and press ⌘ + i (or choose Get Info from the file menu).

Start with the Info tab. Ideally your metadata will look something like this, with obvious differences (unless your file happens to be the same episode of The Big Bang Theory):

Note that the track number corresponds to the episode number

Not all devices use the Info metadata for sorting though, your next stop is the Video tab:

Episode ID could also be expressed as S2E8 but I prefer the cleaner, numerical method.

Next, visit the Options tab to confirm that the Media Type is set to TV Show:

.

To assure consistency, you can select multiple files and edit common fields, such as Album (in the Info tab) or Show (in the Video tab) all at once.

Finally, it's sometimes useful to make change the criteria that iTunes uses to sort your media. You have guessed by now that the Sorting tab is the key to this operation:

In the example above, alphabetical sorts by episode will place this episode with the L episodes, not in the T's. This is useful for Movies, shows or bands beginning with The.

The laborious process of manually entering  metadata for TV Episodes is the main reason for my using iVI to import DVDs.


Running 3 External Monitors off a Mid 2014 MacBook Pro

If you Google Mid 2014 MacBook Pro and go to this link Apple says "Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors."

I added the emphasis.


Options to use iPad as remote photo viewing client

I use Remiew

I can view any photo I saved on my PC from iPad as it gives full control on folder navigation, i.e. I can browse all folders of my pc without any restrictions.

One restriction it that it shows images only, no other file types are shown.

It was a bit tricky to set it up at first, but it works fine for me and it's free.

A complicated script to automate functions in Safari

The following script works for me:

tell application "Safari"
    activate
    close every window
end tell

tell application "System Events"
    tell process "Safari"
        click menu item 6 of menu "safari" of menu bar item "Safari" of menu bar 1
        delay 0.5
        click button 2 of window 1
    end tell
end tell

tell application "Safari"
    make new document
    set the window_width to 1680
    set the window_height to 1575
    set the bounds of window 1 to {0, 22, window_width, 22 + window_height}
end tell


How to sync voice memos with itunes over air

If with "over the air" you mean iCloud I'm sorry but it's not possible. The only way is to use a third party application that use iCloud to store the memos, like this. Instead if you mean WiFi it is possible to do that using iTunes and the normal WiFi sync.

Any WiFi has a bandwidth.

That is the maximum amount of data it can handle.

For example the 5 GHz WiFi can handle up to 8x more data then the 2.5 GHz.

Setting (limiting) a bandwidth usage for a specific application is not easy and Mac does not offer a build in solution, but there might be some external applications for that.

Here are some suggestions how to do that.

However, one can also use the AirPort Utility (in your utility folder) to set the Date/Times for Time Capsule. Set it to Times when you are not using the computer to prevent overcrowding your WiFi network.

How to remove OS X Installer for 10.10. to get back to 10.7, the originally installed OS?

Something really, really bad happened to your internal 1 TB drive:

The GUID partition table was somehow replaced by a dual (and therefore additionally false) MBR partition table.

You may recover the previous GUID and your missing volume with a disk recovery tool like Disk Warrior to some extent. But since you have a backup just restore it:

In case you have a Time Machine backup:

Boot to Internet Recovery Mode by pressing altcmdR. The prerequisites for an Internet Recovery are listed here: Recovery/Internet Recovery.
In a few words you need the latest firmware update installed, either ethernet or WLAN (WPA/WPA2) and a router with DHCP activated for a successful internet recovery.
On a 50 Mbps-line it takes about 4 min (presenting a small animated globe) to boot into the Recovery Netboot image which is loaded from an Apple server.

(Alternatively you may boot to an external drive containing a Recovery HD or a full OS X system or a OS X thumb drive.)
Open "Disk Utility" and partition your internal disk: GUID partition scheme (use the "Options..." button at the bottom of the main pane for this), one partition, journaled HFS+.
Close "Disk Utility".
Attach your Time Machine backup drive.
Open "Restore from Time Machine Backup" and restore your main drive if you have booted from a Recovery drive.
If you've booted from a full OS X external drive just open Time Machine and restore your internal drive.

In case you have a different back-up app:

Follow the instructions of the non-Apple back-up application


How do you position your hand to use the command key? What finger do you use?

You can use either thumb to hold down a ⌘ key and then use another finger to access the other key. You just have to get used to sliding either thumb a little to the left or to the right of the space bar.

Yes, this is just a result of years of using a PC.


You can check which processes are using the most time interval in the system calls:

sudo fs_usage | grep -v 0.0000

See: How do I debug an out-of-control “kernel_task” process?

In case your macOS experienced out-of-space scenario, some services can be still in a freeze mode (causing some freeze timeouts) and they need manual unpause by the following command:

kill -CONT -1

Otherwise check whether clean restart helps with anything.

If you had any unexpected shutdown after freeze, it's good to check for the shutdown code.

If won't help, if you experience another freeze, hit ⌘-⌥-Control-Shift-, (Cmd-Opt-Ctrl-Shift-Period), this will trigger sysdiagnose process which will quickly gather system-wide diagnostic information helpful in investigating system memory/performance issues (will appear in /var/tmp). If you're technical person, you can consider uncompressing the generated file and analyse the logs, or contact Apple support if they can help you.

If you believe you've a virus, just install antivirus (such as Sophos Home) to exclude that. But having antivirus, can cause another extra freezes as well, so it's up to you.


Macbook Air - Blinking folder at startup on occasion

Three startup tones indicates that the RAM installed in your Mac is not passing an integrity check:

  Three successive tones, then a five-second pause (repeating): RAM doesn't pass a data integrity check. If you recently replaced or upgraded your computer's RAM, check to see if it was installed properly.

Misbehaving RAM can contribute to a host of problems, including, (but not limited to,) the startup problems you've been experiencing.


Can Mountain Lion be used as a guest OS under 10.7 Lion?

As far as the license says, no.

You have the right to:

(iii) to install, use and run up to two (2) additional copies or instances
of the Apple Software within virtual operating system environments on each
Mac Computer you own or control that is already running the Apple Software,
for purposes of: (a) software development; (b) testing during software
development; (c) using OS X Server; or (d) personal, non-commercial use.

So, as far as the license goes, you must already be running Mountain Lion in order to virtualize it.


iPad Mini - Stuck in black Apple & White Background loop

Absolutely. This is a problem that has been bothering people for a while but luckily there is a very common solution as the issue is only temporary.

Option 1

Hold down the Home and Power button until the phone reboots.
Let go of the Power button but keep holding down the Home button until you get back to the lock screen.

Option 2

Hold down the Home and Power button until the phone reboots.
On reboot, hold the volume up button until you are back at the lock screen.

Both of these options force a reboot, which in the majority of cases, is all you need to do.
Let me know if that makes sense to you and report back with the option that worked for you. I'd be interested to follow up with you on this.


How to set up my network/bridging using Apple Airport equipment?

Here's what ended up working, via: http://discussions.apple.com/thread.jspa?threadID=2725432&tstart=0

The following are the basic steps to configure a "dynamic" WDS with the 802.11n AirPort Express Base Station (AXn) being extended by the 802.11n AirPort Extreme Base Station (AEBSn). Please compare them to what you attempted to see if anything was missed.

One thing to note is that the AXn is not capable of providing simultaneous dual-band operation like the AEBSn. That said, you will only be able to extend the 2.4 OR the 5 GHz radio of the AXn. Since the lower frequency band travels longer distances, I would suggest extending it.

o If practical, place the base stations in near proximity to each other during the setup phase. Once done, move them to their desired locations.

o Open AirPort Utility and select the AXn.

o Choose Manual Setup from the Base Station menu. Enter the base station password if necessary.

o Click AirPort in the toolbar, and then, click Wireless.

o Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then, select the “Allow this network to be extended” checkbox.

o Next, select the AEBSn, and then, choose Manual Setup from the Base Station menu. Again, enter the base station password if necessary.

o Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then, choose the network provided by the AXn from the Network Name pop-up menu.

o Enter the base station network and base station password is necessary.

o Click Update to update the base station with new network settings.


Mavericks Mail- Sent folder not updating

I had this problem as well after upgrading to Mavericks. The solution for me was to select a different Outgoing Mail Server. My Exchange account was set to use the "Exchange SMTP" server (which worked fine for me prior to Mavericks). The other option in the pull down menu was something called "USERNAME@SERVERNAME (Exchange)" so I picked it. This solved the problem. Sent mail once again appears in my Exchange Sent Mail folder.

The weird thing is that this option is not listed as one of the SMTP servers if I click on "Edit SMTP server list".  Maybe it's something other than SMTP?


OS X Mountain Lion: Change resolution automatically when on battery

Your best bet would be to use ControlPlane (free) to detect when the power source has switched, and then fire off a shell script to change the resolution.

There's no built-in command line utility for changing the screen resolution, but someone came up with one that works well. You can download an installer here.

Then it's just a simple matter of setting ControlPlane to run screenresolution set 1440x900 or 1650x1050 as appropriate. Note that you may want to experiment with the screenresolution get command first to double check how it handles retina resolutions.


Sometimes when wanting to chat with someone I accidentally press the FaceTime option instead of a traditional phone call. Perhaps you might have done so at some point? Or maybe it will log if another person attempted to call you (accidentally) and then hung up?

The other possibility is iCloud syncing Call history. Since iMessage and FaceTime don’t affect the carrier - Apple could sync that history if iCloud is signed in on two devices.

Lastly, handoff could also be in play. Again - look at the iCloud accounts on all devices such as Mac and iPad and iPhone.


Your thumb drive is likely formatted as FAT32 (or just FAT if older).

Copying the app to something that isn't formatted as Mac OS Extended, probably resulted in the loss of things like file owner, permissions, etc, that may have been needed to run/validate it with the system.

Either consider

Packaging it as a .dmg, or
If this is something you might need often, you could reformat the thumb drive as HFS+ (after backing up anything important on it).  Consider copying the app file with the flag to preserve settings:

cp -p source_file target_thumb_drive


Unable to update after iTunes ID has been changed

Apps, books, tunes & even the iOS itself belong to the ID that purchased them.

When you say you have 'changed your account' I'm guessing that rather than simply changing the primary email address on your old ID, you've set up a brand new one.
This will now leave you in the position that each time you need to update the OS or any app, you will need to sign in with the old ID again.

It is not possible to transfer any apps, books or tunes from one account to another so unless you completely erase the device & start afresh with the new ID, repurchasing previous software, then you are stuck with this double sign-in.

The additional problem with having set up a new Apple ID with your new email address is that you can now no longer change your primary address on your old ID to that address.

This is the method to change a primary email address - for future reference.
You may be able to call Apple & see if anything can be done now, but I'm not sure it can.

Change your Apple ID

Follow these steps to change the email address that you use as your Apple ID.

Sign out of iCloud, the iTunes & App store, FaceTime, Find My Friends, Find My iPhone, and iMessage on each device that uses your Apple ID.
Sign in to your Apple ID account page.
In the Account section, click Edit > Change Email Address.
Enter the email address you want to use as your Apple ID. A verification code will be sent to your new email address.
Enter the verification code from the email into the fields provided and start using your updated Apple ID. Didn't get the email?

You can change your Apple ID to any other email address you control, as long as it's not already in use as an Apple ID. If your email address ends with @icloud.com, @me.com, or @mac.com, you can't change your Apple ID and you won't see Change Email Address on your account page.

Connect bluetooth earbuds in Mojave failing

Also try the following

How to install macOS on a encrypted, journaled filesystem?

I know you have a working answer already, but I thought to share my experience anyway, only updated for High Sierra and using Apple's new file system APFS.

My motivation: I was driven by the (constantly varying) 6-14 hour estimate for FileVault to finish on a new install with no additional user data.

So this is what I did to install macOS on an already-encrypted filesystem - much like yours:

Create a bootable macOS installer
Erase and format as APFS (Encrypted)
Install High Sierra

Pros:

< 10 mins to encrypt by Disk Utility? (possibly less, I didn't monitor closely)
FileVault already enabled.

One main difference is that you supply a password earlier when formatting with Disk Utility, rather than being given one (the Recovery Key) when enabling FileVault post-install.

Hope this helps someone.


Yes, you can restore your iPhone via iTunes. And because you have jailbroken your device it's the only way to do it.

Many apps are compatible with iOS 6, but I cannot guarantee you every app will work. This is because some new apps are only written for and compatible to iOS 7.

Email addresses contain @HOSTNAME.domain.com when mail is configured using Profile Manager

Another update...  I started fresh with a new install of Lion.  Updated to 10.7.3 first, having read about everyone's nightmares after this update.

Anyway, my Kerberos realm is now set to domain1.com, but Profile Manager still insists on using the incoming server name (hostname.domain1.com)as the email address.  I tried using both variables, %email% and %short_name%@domain1.com.  No luck either way.

What I find aggravating is that if you view the Profile when it is installed, or in Systems Settings > Profiles, the email address is correct.  This was also the case before I started over.  This leads me to believe that the profiles are somehow not implemented correctly by either Mail or the profile installation process.  I looked at the XML in the profile, and do not see any settings that would be responsible for the behavior.  Everywhere I used a variable, the resulting values were precisely as I expected.

I again tested the default "Settings for Everyone" profile that is configured automatically based on your server settings, and the Server Admin > Mail > General > "Host name:" setting still takes precedence.  So, if you put your actual hostname in this field (i.e. mail.domain.com) your users will all end up using user@mail.domain.com as an address.

I am admitting defeat for now, and just set up A records for domain.com that point to the mail server.  This way, I can set my two profiles up, one for each that use domain1.com and domain2.com, respectively, as their incoming servers.  The email address will then default to %short_name%@incomingserver


What does the "i" in Apple product names mean?

When Steve Jobs first introduced the iMac in 1998, he proclaimed that the i stood for Internet. Jobs went on to say, "i also means some other things to us" and displayed a presentation slide with the keywords:

  internet
  individual
  instruct
  inform
  inspire

You can even view video of this event.

The "i" was first used on the iBook and iMac. These were produced as Steve Jobs wanted a pro and consumer model of a desktop and portable computer. This later rolled out with more products, iSight, iPod, iPhone, iPad.

Yes the products are trademarked, but using an "i" itself before a product is not trademarked and it cannot be. Here is Apple's trademark list


Move external HD to a new drive, but have Time Machine think it's the same?

Instead of using the finder to copy your files - use a program like 'carbon copy cloner' or 'super duper'.

This will get you the closest to the two drives being exactly the same.

However, I should warn you that when I did this myself, I could not get Time Machine to treat the new drive as if it were the old drive. It insisted on keeping a backup of it as if it were a new drive. (however, in my case this was the OS internal drive and not an external data drive)

In the end I decided that it was OK that Time Machine didn't know it was the same drive, as I now had two copies of the data (before time machine even backed up) from the original flaky drive, and the new drive.

I just had time machine back up the drive as if it were brand new. I haven't had any regrets about it.

Hope this helps.


Can I use HDMI for audio only without video?

If all you want is to have your desktop confined to your computer's screen, go to System Preferences > Displays > Arrangement, and check Mirror Displays. That'll make it so that your HDMI display only acts as a mirror of the desktop you already have, rather than an extension of it.


I know of and can recommend two different ones because I had two employees that, due to medical issues needed these keyboards.  One was a photographer and the other was a programmer.  Both swore by them.

That said, the Microsoft ergonomic keyboard works just fine under on a Mac.  In fact, I have both the Apple keyboard and a Logitech K380 (Windows) keyboard hooked up simultaneously and both work just fine.

There are few reason why the Fan run at high speed.

1- is when something is actually running hot and Mac needs to cool it

2- a Fan controller SMC is misbehaving and needs rest

3- a hardware failure from a Thermal sensor

---------------Fixing

A 3D party Fan speed software will not fix anything

1- to check that look in the Activity Monitor to see who is consuming CPU and shut it down.

2 - Reset your SMC, it is your model dependent so look it up. Since it can be tricky to do, watch the magsafe light briefly changing the color as you do the reset.

3 - if none of the above worked you might have a faulty temperature sensor. see Apple service for that.


Are there any third party displays that have similar resolution and image quality to the Thunderbolt Display?

The last time I checked up on this, about 6 months ago, the only monitor I could find that matches the Apple display was the Dell UltraSharp U2412M. However it's a 24" and it wasn't that cheap. Dell does however have a bigger model in the range which is the Dell UltraSharp U2711.

Both are brilliant.

I ended up buying a 27" iMac and stopped looking further


Does Touch ID erase the device after failed tries?

Quoting from About Touch ID Security, from Apple’s website:

  Touch ID only allows five unsuccessful fingerprint match attempts before you must enter your passcode, and you can’t proceed until doing so.

You then get ten attempts at your passcode before the device erases, but these are counted separately from attempts to authenticate with Touch ID.

This is slightly different from the other answer:

After three attempts, the iPhone will present the passcode screen, but you can still have two more tries at authenticating with Touch ID.
After five attempts, Touch ID is disabled until you successfully enter your passcode.

Apple’s security documents don’t mention a setting to erase the device after failed Touch ID attempts, and I’m not aware of one. I don’t believe that iOS devices would erase themselves after five unsuccessful attempts, at least not with the current version of iOS.


After asking to be remembered to return a call, geofence won't go off

To disable the reminder, open Reminders.app and check the "Call [person]" reminder.

With location based reminders, they will go off every time you enter (or leave, depending on the setting) the area until you mark them as completed.

Very much a side note, but in iOS 9 you can now keep tabs on what apps are draining your battery. So if you are concerned about battery drain, go to Settings -> Battery and validate (or invalidate) those concerns.


To find out which app is preventing the shutdown use

alt + cmd + esc

Try to force quit it from that screen.

If all fails hold the Power button for 10 seconds.

That is the most crude way to shut down and as last option.

Problem creating a Windows 10 bootable USB on Windows, to work on a MacBook Pro

I assume you are trying to install Windows 10 on the MacBookPro 2013. Your question does not provide enough information that can be used to generate an exact answer. I would need to know which version of firmware is currently installed on your Mac. This firmware is tied to the latest version of macOS (OS X) that was installed on your Mac. You may need later firmware to boot the Windows 10 installer from an ExFAT formatted volume. Also, I would need to know the Windows 10 ISO version and how the ISO was obtained. The contains of early Windows 10 ISOs would fit on FAT32 formatted volumes. The latest Windows 10 ISOs can contain an install.wim file that exceeds 4 GB file limit of FAT32 formatted volumes. However, the latest Windows 10 ISOs download on a PC using the Media Creation Tool may instead contain a install.esd file that would fit on a FAT32 formatted volume. However, Apple recommends using the Windows 10 ISO directly downloaded from the internet.
Finally, to install Windows 10, you need the correct Windows Support Software for your model Mac. The usual method of acquiring the Windows Support Software is by directing the Boot Camp Assistant to download. This would require first installing the latest macOS compatible with your Mac. After downloading to an external drive, you can erase the internal SSD. Using the Boot Camp Assistant installed on a different Mac will probably result in the wrong Windows Support Software being downloaded. You can also download the Windows Support Software using a PC, but this is a far more complicated process. Therefore, I would recommend using the PC to download the Windows Support Software only as a last resort.


Tables with Arabic numbers (iWork) only show Western Numbers

I can see why this might be frustrating. Tables in iWork by default are set to automatically detect the type of text that is entered in each cell. If iWork sees a number (of any type) it converts it a Western character. Luckily it is possible to change this.

Open the inspector and go to the table settings section. Under the table settings section you are presented with two other sections ("Table" and "Format"). Select "Format" and you will see that you can set the "Cell Format" of a table. Select the table in your document and and click on the "Cell Format" drop-down menu. As you will see, the current option is set to "Automatic." Change this to "Text" and you will no longer have the problem of iWork changing your input to Western characters!

Note: You may be forced to manually create and enter the values in the table using the character viewer or copy and paste individual characters from Wikipedia in each cell AFTER initializing the table to have the "Text" cell format. Copying and pasting the entire table from Wikipedia seems to override any initial formatting (in the form of cell format) in iWork.


Why does GPS on the iPhone use so much power?

To obtain a semi precise GPS position, you need at least three satellites (but usually four or more is required to obtain a decent degree of precision) to triangulate your position. The more you have the better the accuracy.

A GPS receiver needs to power its antenna, and constantly process the signal sent by each satellite. Remember that satellites are continually transmitting messages. (50 bits/sec as far as I can remember)

Satellites emit messages specifying their exact location, trajectory, speed, the time each message was sent and the rough location of all the other satellites in the constellation.

By comparing this info to the time the signal was received a distance from the satellite to the receiver can be determined. When you have three or more satellites you can triangulate your location in three dimensions relative to the positions of the satellites.

The iPhone (and other phones) use A-GPS, which is designed to (believe it or not) among other things, make the GPS work better in poor reception areas (cities?) and reduce the amount of information that the receiver needs from the satellites, thus saving battery power from the Antenna.

The parts of the GPS signal about location, speed and orbital trajectory usually drop out first when in low reception, that’s where A-GPS fits in, feeding that info for every satellite in that part of the world to the phone, from a central database via the mobile network. Now the phone just has to search for the short timing signals from each satellite, which are easier to receive than the other parts of the transmission.

When all that information is calculated, an algorithm (there are a few as far as I know) is used to compute the position of the actual receiver.

Now add to that the fact that GPS messages are encoded and that satellites broadcast the messages at about 50 bits per second. And that each message is really a subset of frames with time, position, error correction, etc, etc.

There are more factors involver, but for the purpose of making this simple, the GPS’s cpu must constantly use the radio (already power hungry) to capture the signal (which may be weak!) for usually four or more (sometimes up to 20!) satellites that are constantly sending packages, then it must decode and process them, perform calculations to analyze the results and in some cases draw a map or feed an application with the info.

As you can see, this sounds easy but it’s not. There’s a lot of CPU processing involved in the back (plus the antenna’s power!)

So the GPS power consumption usually comes from the real time nature of the operation. Powering the antenna, listening for information and processing it, uses power, more than just a standby radio antenna (the phone) waiting for a call. Plus the A-GPS uses also the phone’s radio and (if available) Wi-Fi networks to determine its location (and use less GPS info), which means, more power is used at the same time.

The Wikipedia GPS page has a lot of detailed information if you want to get the specifics and/or dive into more GPS geekery, including the math and error correction stuff.


Just "spitballing" here, but do you have a Time Machine backup?

If so, search it for 'index.xml'.  If you find a file that resides in a Numbers 2.2-related folder, copy it to the present and put it in the same spot where you found it in the "past".


It seems that after a little more research, I was able to recover my issue with a more aggressive fsck_hfs -drfs /dev/disk0s2 call.

Is there a software to reset/flash your iphone to factory without itunes?

There is a reset button that lets you reset several different properties to factory settings. If you open 'Settings' on the phone (if you are able) and goto 'General'. At bottom of 'General' is a reset button. Tapping that brings up options for reset.


Change directory in Terminal if working folder moved to Trash (in interactive shell)?

No, there's no way for Zsh to automatically notice that while you are not actively using it.
But what does it matter? You can just type cd to go back to your home folder.
Update
All right, here's a real solution that I've tested and it works. Thanks to @nohillside for the encouragement!
autohome() {
  # If the present working dir doesn't exist...
  if [[ ! -d $PWD ]]; then
    # Go back to ~
    cd $HOME

    # If the line editor is active, redraw the prompt.
    zle && zle .reset-prompt
  fi
}

# This will call the function above as soon as you start typing.
autoload -Uz add-zle-hook-widget

Basically, the grid view was replaced by the new tabs in Mobile Safari in iOS 5


How can I get my Macbook Pro with Yosemite OS and Parallels Desktop 10 to run a Windows only application?

I run Parallels in the environment you describe and that is not how Parallels behaves for me.  I believe your installation or configuration is corrupt / invalid somehow and you will definitely need to contact Parallels support and / or start over with your Mac OS / Parallels installation.  Personally I recommend contacting Parallels support.

For myself, all Parallels drop down menus appear and work fine.  I am able to switch from Coherence mode to Full Screen mode, etc. easily without issue, and of course launch Windows only applications just fine.

So far as I can see, there is no answer to your question other than to reach out to Parallels support and / or start with a fresh installation.  Once setup Parallels works great by the way.  Good luck!


There is a paid ($3 in US) application Cascadea. I’m happy with it, because it is Safari App Extension instead of the Legacy Safari Extensions (.safariextz files). It seems to only work with User CSS (*.user.css) though, so you may want to write to support team (support@cascadea.app) to confirm before you pay.


How to mount local folder with mount_afp in OS X 10.6.8

I don't think Mac OS X allows you to connect to your own machine for AFP mounts.  For example, if you go to the Finder, select Go > Connect to Server, and type "afp://localhost", it puts up a dialog saying:

  Connection Failed
  The server "localhost" is available on your computer. Access the volumes and files locally.


Safari Running slow on iMac under OS 10.4.11

If you are keeping an application like Safari open and constantly running for multiple days at a time, this is the reason itself that is causing you the issue.

When you quit an Application, not close its windows, but actually quit it by either clicking on the name of the application in the top left hand corner and choosing quit or by hitting Command + Q while in the application, it will free up its RAM and resources that it is holding on to.

This happens a lot for people who don't like to restart their machine and constantly leave things running or always open.  Its convenient, no argument there, but it can bog down your computer because it is constantly holding onto everything you have been doing.

It would be similar to never cleaning off your desk, always keeping everything you need on your desk at all times.  Things would pile up and pile up and get more and more cluttered.  Its convenient because you have everything in arms reach but after a while, the time it takes to find things in the piles of stuff that you have becomes longer and longer.  That is what safari is doing, it is keeping track of all the stuff you have looked at and watched and done on the internet, just in case you want to return to it quickly.  By leaving Safari open and running for days at a time, it is lugging around so much stuff that even doing simple things becomes a chore.

Now I am not telling you to turn off your computer every time your done using it.  Using sleep mode is fine, but just remember to quit your applications.  An easy way to see what Apps are open is by hitting command + tab.  If there are a lot of things open, quit them.  If they are quitted, they won't show up in the little box that pops up when you hit command + tab.  Restarting your machine is good to do every couple of days, because it lets the computer free up resources that it may be holding on to that you probably aren't even using.  Its just part of regular computer maintenance.

Some people will say to never restart your machine and others will argue and tell you to restart it or turn it off when your not using it.  Everyone will have their theories and opinions when it comes to this.  The important thing to remember either way is that you need to quit the apps that your aren't using anymore.  If you are putting your computer to sleep, and you don't need what was open anymore, close those applications, free up the RAM they are using, give more resources back to the computer so that when you pull it back from sleep, it will be ready to work, instead of remembering to lug around those things you don't care about anymore.

You can also google search ways to keep your mac running smoothly, and you'll notice usually in that list is the advice to quit applications when not in use.

I know this was kind of winded, but I hope it helps you keep things optimized and running smoothly.


How to turn on email notifications when Find My iPhone is used?

You can't turn off email notifications, so they are being sent, but not being delivered. Check that the email address is correct and the emails are not being delivered to your spam folder.


How to logout from iCloud without password? and without resetting

You cannot sign out of Find my iPhone without the password from the previous account.
The previous owner needs to sign out from the web, the device does not need to be returned to complete this process.
These are the instructions the previous owner should follow. The new owner is you.

If you no longer have your iPhone, iPad, or iPod touch
If the steps above weren't completed and you no longer have your
device, use these steps:

Ask the new owner to erase all content and settings using the above steps.
If you're using iCloud and Find My [device] on the device, sign in to iCloud.com/find or the Find My app on another device, select
the device, and click Erase. After the device has been erased, click
Remove from Account.
If you can't follow either of the above steps, change your Apple ID password. This won't remove personal information that's stored
on your old device, but it prevents the new owner from deleting your
information from iCloud.
If you're switching to a non-Apple phone, deregister iMessage.
If you're using Apple Pay, you can remove your credit or debit cards at iCloud.com. Choose Account Settings to see which devices
are using Apple Pay, then click the device. Next to Apple Pay, click
Remove.
Remove your old device from your list of trusted devices.

Sudo keeps asking for password, despite that NOPASSWD already set

The group entry %admin  ALL=(ALL) ALL seems to override the user specific entry.
I found moving the user specific entry so that is appears after the group entry fixes this. Maybe sudo parses the entire file and it uses the last matching entry?

Changing your sudoers file to something similar to below should work.

# User privilege specification
root    ALL=(ALL) ALL
%admin  ALL=(ALL) ALL
howard  ALL=(ALL) NOPASSWD: ALL


Use the Downloads folder as shared folder between two Macs with Dropbox

I would probably be simpler in the long run - if a little tedious depending on how many apps might use that Downloads folder - to set your Dropbox folder to be your download destination, rather than trying to persuade Dropbox to use another folder.

For Safari, set it in Prefs > General. Click download location, select other & navigate to your Dropbox folder.

You would have to do the same for any other apps that would use your standard downloads folder - but I'm certain it would be easier than trying to persuade Dropbox to use your original Downloads folder as its shared location.

I'm sure the alternative would be to make a symlink from Dropbox to Downloads, but I'm just not convinced it would be simpler to maintain.


How to "star" messages or mark them as important in iPad mail app?

Since the release of iOS 5, it it possible to flag messages using the "Mark" dropdown menu.


How can I automate clicking in a Chrome extension popup with a hotkey?

I haven't found a free solution, but I've been able to solve my problem with the free-trial version of Keyboard Maestro.
KBM allows you to record key clicks and mouse motions, and with an option on the Recording process, you can include real-time time delays that can then be edited to speed up the process without it zipping along too fast for the apps and app switcher to keep up.
On thing about KBM that is very useful, as hinted at in my problem description, is that the mouse clicks are initially recorded relative to the upper right corner of the screen or the frontmost window, BUT, after recording, you can change what the zero-point is for the mouse coordinates. In my case, changing the mouse clicks to be relative to the upper right corner means that they should be pretty stable w.r.t. where the RenameTabs Chrome extension dropdown dialog appears.
I still don't know how to capture the current window size, which would be required for a totally free solution. One option I've thought of is to use another Chrome extension, Easy Window Resize, to ensure that that the window is always at a predefined size so that I can indeed use Cliclick relative to the upper left corner. That could be a free solution.
I probably won't go that way for my own purposes because, the other features of KBM make it look like a worthwhile investment for me.
DISCLAIMER: I am just a customer, currently using the free version of KBM and am not affiliated with the company in any way. I haven't even paid them anything yet.


iMac wont startup and won't boot from CD

From what you describe, your internal hard drive failed, which will require a replacement;  since you have an iMac, I suggest that unless you’re very comfortable using a variety of tools and have time, let Apple do it for you. In any case, what you can try to do is, connect an external USB/FW drive and try to install into that drive.

The fact that your drive doesn’t want to boot from the DVD is intriguing if anything, but the DVD may be crashing when reading the “broken” drive. It’s rare, but it could happen. Do you have any other Mac to “clone” into an external drive and try to boot from there?

Since it’s an iMac, your best bet is to remove the internal drive and proceed from there. The problem is that removing the drive is a painful operation.

Best idea: go to an Apple store or certified shop. They have the tools and the spare parts to better diagnose the problem.


Where did folder "merge" or "keep both" go in OS X 10.9 Mavericks?

OK. I found out myself... Luckily Apple did not remove the Finder Merge functionality with Mavericks. But sometimes it is not offered to the user. But let me explain:

Supose you have a folder named TARGET with a subfolder TARGET/SomeStuff. And you have a SomeStuff folder somewhere else. Now drag this second SomeStuff folder to the TARGET folder (without any modifier keys pressed) then the Finder will presented you the following dialog (Stop and Replace):

So, no merge here.

Now - if you instead press the Alt key while you drop the SomeStuff folder to the TARGET folder there are two possibilities:

1.) If the files in the two SomeStuff Folder have completely different (not overlapping) contents. In other words: no duplicate filenames. Then finder will give you these options (Stop, Merge & Replace All):

So, here you can merge. And the result will be a TARGET/SomeStuff folder with the content of both SomeStuff folders.

2.) But here comes what is sometimes confusing (and actually made me think merging is gone in Mavericks): if there exists at least one filename that is contained in both SomeStuff folders, then merging is not possible. Then the finder will offer you these options (Don't Replace, Stop, Replace):

So, no merge possible, here too!


How do I disable "modern login items" (shared helper applications) which don't show up in system login items?

There are several ways that programs can automatically start in macOS:
First check "Login Items" which are found in System Preferences after clicking the "Users & Groups" icons. I understand that you have already checked here and did not find Spotify.
Another possibility is that Spotify have been set to open at login from the dock. You can right-click the Spotify icon in the dock, and then in the Options menu make sure that "Open at login" is not enabled.
Similarly if you have left Spotify running when you power down the Mac then by default the app and open windows will be opened again after rebooting. You can avoid this by ensuring that you close Spotify before logging out or rebooting, or change the setting in general by clicking the "General" icon System Preferences and making sure there's a checkmark in "Close windows when quitting an app".
A third possibility is that it is possible to create configuration files for launchd that will automatically start programs at boot or login. You'll find these configurations files in:
~/Library/LaunchAgents/
/Library/LaunchAgents/
/Library/LaunchDaemons/

Note that the ~ characters means your user's home folder.
A final possiblity is that applications in macOS can come with a "shared helper application". Essentially this application would provide some background service to one or more actual applications from that developer. Some use that helper application to later launch their actual application.
The helper application is located within the application's bundle in the Contents/Library/LoginItems folder. For Spotify that is usually in the following location:
/Applications/Spotify.app/Contents/Library/LoginItems/StartUpHelper.app

You can prevent that from autostarting Spotify by closing the helper app, or making sure that it cannot start (for example by removing the executable bit on the actual executable: /Applications/Spotify.app/Contents/Library/LoginItems/StartUpHelper.app/Contents/MacOS/StartUpHelper)


Can I swap an Apple SSD from one laptop to another?

I'm pretty sure it will work by just swapping the SSD. But remember a few things:

You will void the warranty by opening up the laptop
You might break the laptop if you are not experienced in opening it up.

I would just recommend a USB SSD drive enclosure like this one (definitely not the best one but it works). Then transfer all the datas from the old SSD to the new one. Plus you can use the old SSD as an external storage.


Open Automator and do something like this.

Use Workflow + Drag New Calendar Event to the right. Choose the time+date. Choose what file to open.

Obviously set the date/time and choose the right file to Open.


Mac Freeze and Screen Goes Weird After RAM Upgrade

TL;DR: You probably want to exchange the RAM you bought for new sticks.

From your picture, it looks like that's a MacBook Pro (13-inch, Mid 2012). As you mentioned, it does support 2x8 GB (16 GB total) at 1600 MHz (PC3-12800).

If the issue doesn't occur with the original RAM, you can be fairly sure that your memory slots are good. It's very likely that the issue lies in the modules themselves.

You can use a tool like Memtest86+ to test the RAM completely to help narrow down where the issue is. It could be one stick, or it could be both.

I recommend installing a single 8 GB stick, running through the full battery of tests, and then repeating with the other stick in the same slot. By testing them one at a time, you can easily determine which module is bad.

If both pass, then you can try the same together. If they only fail as a pair, there could be a timing issue or something else going on with the RAM.

To be absolutely sure that there's not an issue with your memory slots (read: logic board), you should test your old modules as well.

Finally, you mention that you purchased 1600 MHz RAM, but you'll want to confirm that. A common issue with Mac RAM installation is the use of higher clocked RAM under the assumption that it will correctly work on boards that want a lower clock.

For example, if you bought 2x8 GB at 1833 MHz, you might expect it to downclock to 1600 MHz for your computer. While normally that's true, Mac logic boards are very sensitive to the clock speed. Often, you'll get kernel panics, graphical issues, and general instability even though it may report as the clock speed you expect.

The solution is to purchase RAM that's the exact speed you want.


I don't believe any carrier offers straight SMS from an iPad so you will either need an app that contacts an SMS sending service from the App Store or to ensure that your recipient signs up for iMessage.

Apple provides iMessage for free and it replaces SMS as opposed to interfacing with the SMS.

So, you could only send iMessages to Computers that run iMessage and iOS devices that run iMessage - but not actually send a SMS to cell phones.

http://www.apple.com/ios/messages/
http://support.apple.com/kb/TS2755

If iMessage seems to be something you want to try - sign up for free according to the instructions on the first link. The second link explains the difference between SMS, MMS and iMessage services and when they can commingle on iPhone. Again, iPads only support iMessage out of the box (i.e. without adding a third party app).


How to find out which process eats up memory?

Check with this command (will show more processes):

sudo ps -awxm -o %mem,rss,comm | sort -nr | head

if won't help, check with fs_usage to display system calls and page faults related to filesystem:

sudo fs_usage -f filesys,diskio

especially page in and out by appending the following to above command:

| egrep -i "page_|pgin|pgout"

Add extra | grep -v kernel to ignore kernel process or | grep -v 0.00 to show these with higher time spent.

If your swap is big, you can force disk cache to be flushed and emptied by: sudo purge.

Based on my experience, OS X have some issues with managing the memory after higher uptime (when it used all of free memory), so sometimes only full restart may help.

Check also sudo iotop or sudo vm_stat 1 commands which may help.

Can anyone tell what does the number 33 mean in my lock screen of iOS 10?

Note: This was an issue in early betas of iOS 10. The correct string in Chinese characters is displayed in Developer Beta 3/Public Beta 2.

Original Content:

The number is the current "year" in the current cycle of the Chinese Sexagenary Cycle.

Year 33 of the current cycle corresponds to 丙申 in the Stem-Branch system, which is displayed when the date is displayed in the Calendar application (both iOS and OS X/macOS).

General formula for converting years 4 AD/CE and later is floor(western year - 3)/60), where floor is equivalent to taking only the part in front of the decimal.

Example: floor((2016-3)/60) = floor(2013/60) = floor(33.55) = 33

See the link for more details on the system.

In iOS, previous versions may have displayed the long string which can be seen when opening the Day view of the Calendar app.

To enable/disable this display, go to Calendar > Alternate Calendars in the Settings app.


How to save on iCloud a WhatsApp call record?

The best solution is to put the call into speaker mode and use a voice recording app:

  Then when you want to record the call, open your voice recorder app, start recording. Then also open whatsapp, call your contact and put the phone on speaker mode, this will then record the call at highest voice quality for you without any Automatic call recording apps.

Then you can add the file to iCloud Drive. On iOS you can access iCloud Drive in the Files app.


Does the 2017 iPad Pro 12.9 have better speakers than the 2015 iPad Pro 12.9

I have all versions including 2018 one, all of them have 4 speakers but the 2015 has the best sound quality between all models from 2015 to 2018.
It has the most balanced sound, the best high and mid ranges, the low register is also sounds better even if it has less low frequencies.

As for 2017 version. It's 5-7% louder than the 2015 version but its mid and high ranges are less detailed (not pleasant to hear comparing to the 2015, even w/o comparing it's obvious that something is missing, the low end on the contrary is too loud and bulky that ruins the whole balance. Also it tends to overload the sound volume so it can give you a harsh/cracking sound, so I'm disappointed in this regard.

As for the 2018 version (12.9), again it sounds like from the closed barrel, does  not have enough mid and high range, the low range became even more punchier than the 2017 one, not pleasant. It's very loud but not balanced at all. the 11 inch version has a better balanced sound than the 12.9 version although it's not that loud.

For example if you record a voice (thru ext Cardioid Condenser Mic and listen it on 2015 version it sounds almost identical to the original) but both latter versions lack of high and upper mid ranges, so your voice sounds like it was recorded with some foam rubber placed between your mouth and the mic.

Another example in Garage Band you need to add about 15% to treble in order to get similar sound in upper range.


Apple recognized repair service asking for password?

It's pretty common for a repair facility of any kind to ask for a username/password for the sake of verifying functionality. This is why it's always a good idea to have a separate administrator account setup for these kind of tasks. Usually an "Administrator" account with a unique password works.

I've worked in the IT industry for almost 20 years, and I've always appreciated when a user has a separate admin account. It makes working on the machine faster as there usually isn't as much stuff loading on start up. It also keeps me from seeing any of your information, which is great for legal reasons.


How does the iPad expose its host name over the network?

The iPhone can be found by name using Bonjour. The name will be my-ipad.local
This name is the name in theIOS device with spaces and some punctuation removes as in @TheX's answer and then local as the domain telling devices to use Bonjour lookup. this name is not held in the router, Bonjour asks devices to call out their name on the network.


I want to Remove an old app in my AppStore Connect

You can't add or remove apps from a bundle that has already been approved for sale.

Source

  Can I add or remove apps from an app bundle?

  You can only add or remove apps from an app bundle before it has been
  approved by App Review. If your app bundle has already been approved,
  you must create a new app bundle.

Create a new bundle with the apps you want, then retire the old bundle or perhaps at this point, contacting the apple developer store support team would be wise if you’re not certain how bundles work for removal. Making two bundles when you don’t like the one bundle you already made might not help things.


Does moving photos to multiple USB drives make the photos decrease in quality?

No, just copying the file can't degrade the quality. You can copy ad infinitum, and you should always end up with an identical digital replica.


Can Macbook Pro 13 drive Apple Cinema Display on full resolution?

Both the MBP and rMBP do 2560x1600 on an external monitor.  The 27" ACD only does 2560x1440 so it will not max out the full resolution capability of either laptop.


Can't connect second external display (but only at home)

You need an active HDMI adapter.

The signal that comes out of your Mac is DisplayPort.  It has to convert the signal to HDMI to make it work.

At work, your dock is creating that HDMI signal so in effect, it's got an active adapter built in.
At home, you've got an "HDMI to DVI" cable meaning the pins just get re-orderd, but the signal doesn't get properly recreated.

To get the best reliability, try to avoid HDMI altogether.  It's a "consumer electronics" standard and (IMO) not up to the bar with respect for computing.

As for connecting/converting signals, the order or reliability is as follows:

DisplayPort → DisplayPort.  It's the native signal coming out of your Mac, so no conversions mean better reliability
DisplayPort → DVI.  DVI signaling is very compatible with DisplayPort and many times an active adapter isn't necessary, though I personally still use one because I don't like dealing with these issues once I have all my cabling in place.
DisplayPort → DVI. The signals are different, especially the clock signal, which is where a number of issues arise.  You can "fix" it with a reboot which allows the signals to "sync" up.  But disconnect/reconnect and a reboot is again necessary.
HDMI → DVI.  IMO, this should be avoided, but if you must convert these signals, an active adapter is really the only way to ensure reliable connections.

Note:  These issues aren't as prevelant in Windows because the drivers for the adapters seem to have more tolerance for the signaling discrepancies.  macOS, has much less tolerance, thus the need for quality active adapters.

If you can swing it, I would get a dock similar to the one you have at work.  It will get you the best reliability and most flexibility.

Volume password challenge in Migration Assistant

I resolved the Volume Password issue. I did two things, so I don't know which of the two actions resolved it or if they both played a part together. If you encounter the same Volume Password issue, maybe your scenario will resemble mine and this will help you, too.

The accounts on my target iMac had issues with their iCloud configuration. I reentered the authentication for those iCloud accounts.
Returning to the Migration Assistant, this time when I ran through the wizard I waited for the source accounts and documents to be identified completely before advancing to the next screen which prompted me to create a password for the administrator account I was migrating. Formerly, I created the password on that screen before the previous screen completed identification of the file sizes to be migrated, while going back and forth between the two screens until the file sizes were calculated completely.

This time, I waited until the file size calculation was complete before advancing to the next screen for creating a password for the administrator account I was migrating.
The next screen is where, formerly, Migration Assistant challenged me for a Volume Password. This time, the prompt didn't refer to a "Volume Password," but instead said it needed authentication for an account authorized to create a new user. I realized this meant an account on the target machine. That must have been what it was trying to do at this point before. I still don't know why it didn't work in the former case, because I know that all the passwords I tried included those target machine accounts, too, and they didn't work. This time, instead of challenging for a Volume Password, the screen identified for me the name of an administrator account on the target machine.
I supplied that account's password and the migration began.
So, it works now. As an extra reward for surmounting this surreal problem, while I was fixing my iCloud synchronizations I got the attached error message. Mind you, there is only one iMac on my network. The source for my migration is a MacBook Pro.
This is a perfect OSX koan and it is my single favorite error message ever.


How do you turn on "show pre-release updates" in yosemite?

@Marksorry I can't comment your question directly, since I'd need 50 reputation to do so.For your question: Wen you quit your subscription for the seeds you basically uninstall a program on your Mac. You can re-download that program directly from Apple and install it. Since the Beta-Progamm is linked to your Apple-ID you have to log in with it. Once you downloaded that file (YosemiteBetaAccessUtility.dmg) you simply install it and you have access for the Pre-Release Updates again. Just open Appstore and install the updates.I found the file with the following steps:

Go to appleseed.apple.com
Click "first steps with OS X Yosemite Beta"
Scroll down the site till you find the button where you can download the Beta Access Utility.
Download and install
Restart if needed and it's finished


Is there a way to preserve app icon categories (folders) in iOS when factory resetting an iPhone?

I found this, and it works:

Say you restore your iPhone with a full wipe and restore. Then you choose a previous backup to restore all of your settings and applications. When your iPhone is done restoring to your backup, all your icons are mixed up on the SpringBoard.... what the heck? You want to get them back don't you? Well, I know a trick and I don't think it's documented anywhere. Here it goes.

**Important: Before starting these instructions, backup your iPhone. Then go into iTunes preferences and turn on "Disable automatic syncing for iPhones and iPods" This way your backup won't get overwritten after your iPhone gets restored.

Restore your iPhone and let it restart and activate.
Then iTunes will happily ask you if you want to restore from a previous backup (with all of your settings and Applications). Click the backup you want to restore to and let it restore and reboot.

(Here's where things get messed up. Your iPhone backup actually restored the correct icon positions except none of your apps were installed before the restore was complete, so iTunes has to copy all of your apps back to your iPhone. When it does this, it copys them in alphabetical order, thus messing up the location of all your 3rd party icons). Here's how to fix this without memorizing where all your icons went.

Right click (or Control-click) on the iPhone icon in iTunes and choose "Restore from Backup" and choose the backup you chose in step 2 again.
Let your iPhone restore for a second time and when it reboots, all of your icons will be in their original places. (This is because iTunes didn't have to install the Apps because they were already there, thus keeping them in their original locations according to the backup).
Return your iTunes preferences and uncheck "Disable automatic syncing for iPhone and iPod"


Paste the current date-time in OmniOutliner

From the menu Edit->Insert Time Stamp - and you get a set of options.

Some of those have short cut keys e.g.

On a US keyboard

⌘| for Short date and time
⌘⇧| for Long date and time

Difficult on a UK one as you need shift to get a | so you only get the short date and time.

See the OmniOutliner help. It has a detailed entry for Edit menu


Correlation between Mac OS X GUI actions and Logs

There isn't a general way to do this.

Most of the things you do in the GUI don't run command-line tools, they use thing like system calls to do things directly. For example, when you run mkdir from the command line, it uses the mkdir() function to actually create the directory. Finder doesn't bother using the mkdir command, it simply calls mkdir() (or something equivalent) itself.

This causes two problems for what you want. First, system calls aren't generally logged; and second, there isn't always an easy way to figure out what command would do the equivalent thing (if there even is such a command -- there isn't always).

There are ways to get some info about what's going on behind the scenes of GUI programs, but they're not particularly easy to use (or interpret the output from).

The fs_usage command will list file system events (including things like directory creation) as they happen... but a lot of file system events happen all the time, most of them completely irrelevant to what you're interested in. Filtering out what you care about tends to be tricky. And of course it's only useful if it's a file system event you care about.
DTrace can be used to trace things like system calls in detail, if you know what calls you're interested in tracing. Recent versions of macOS restrict the ability to trace most Apple programs (Finder, System Preferences, ...), so you'll need to at-least-partly disable System Integrity Protection to use it effectively.


Is there a keyboard shortcut to select the printer in Mac printer dialog boxes?

Add a new shortcut to System Prefences > Keyboard > Shortcut > App Shortcuts.

Choose an existing printer name (in my example Lexa - a Lexmark printer, a Kyocera is my default printer) and enter a shortcut:

To print with this (obviously non-default) printer enter cmdP, and once the Print dialog displays, enter altcmdP to switch to the other printer:

To print with your default printer just use the common cmdP.

After rebooting and configuring your system download and install macOS Sierra.


Cannot edit /etc/fstab to let NTFS drives write

You need sudo to perform the write to /etc/fstab and not the echo. Try:

echo "xyz" | sudo tee -a /etc/fstab > /dev/null

I added the > /dev/null to suppress the echoing of the long UUID (which I abbreviated "xyz" for clarity's sake). You can skip the > /dev/null part and it will function the same as the command you listed.

echo "UUID=7575C85E-F6F7-4ABD-B7FB-6180B795DD81 none ntfs rw,auto,nobrowse" | sudo tee -a /etc/fstab

....


Configure Swipe between full screen apps

If your mouse has it's own drivers, much like Razer Synapse, you can assign ^ control+← and ^ control+→, the shortcuts for moving left and right a space, respectively, to certain mouse buttons.

This cannot be done natively in macOS Mouse System Preferences. A third-party app/driver is required to do this.


Using "Stop Time" option prevents play count from being updated

It's somewhere between a bug and not-a-bug. Play count increments when the last sample plays (or something roughly equivalent). But the duration metadata options don't actually change the file, so the very end still exists, but is always skipped. So, the play count never increments.

The only workaround I know involves changing the audio file itself.

If you're using mp3s (or AAC or another lossy codec), doing this in iTunes involves re-encoding (transcoding) an already lossy file, a minor pet-peeve of mine and something I do not recommend. I suspect there are paid audio editing tools which can cut an mp3 without further losses, but I don't know what they might be.

If you're using apple lossless (or wav), or you really don't care about transcoding, you can do it simply enough in iTunes:

I'm assuming you've already set the start and stop time metadata appropriately.
In iTunes, go to Preferences -> General -> Import settings... and set everything to match the encoder settings of the original file (you can see this info by choosing "Get info" on the song in question).
Select the song, right click it and choose "Create [codec] Version", where [codec] is whatever you selected (for instance, if you chose ALAC it will say "Create Apple Lossless Version").
Done. iTunes has truncated the audio file to the limits set by your start/stop time metadata.


Question about defining custom paragraph styles in Pages

You control both those issues from the MORE tab on the Text Inspector window.

The drop-down Following Paragraph Style will determine what the next paragraph's style settings are.

For example, if your paragraph style for character names is called CHARACTERS and for dialog it is called DIALOG what you do is select a bit of text that is using the CHARACTERS style, then in the MORE tab, set the Following Paragraph Style to DIALOG.

Likewise, you set the page break parameters in the same MORE tab.

By selecting the Keep with following paragraph will force the CHARACTERS style to always be on the same page as the next paragraph. If there is enough room to display the CHARACTERS line and at least 3 lines of the DIALOG the text will start on the current page and then continue on the next page. If there isn't enough room to display the CHARACTERS line and at least 3 lines of the DIALOG, the whole group will be pushed onto the next page.

According to Apple:

  Keeping Paragraphs Together on a Page

  You can choose to make two paragraphs appear on the same page. The last line of the first paragraph will always remain on the same page as the beginning of the next paragraph, unless you insert a page or section break between them.

  This is most useful for single-line, header paragraphs that you want to keep with the topic paragraphs following.
  To keep paragraphs together on a page:

  Click the paragraph that you want to keep with the paragraph following it.
  Click Inspector in the toolbar, click the Text button, and then click More.
  Select “Keep with following paragraph.”

If you want to keep the entire paragraph on the same page (so, not have it break across pages, you select Keep lines together.

  Keeping an Entire Paragraph on the Same Page

  You can make all the lines in a paragraph always appear on the same page.

  To avoid breaking a paragraph across pages:

  Click the paragraph whose lines you want to remain together.
  Click Inspector in the toolbar, click the Text button, and then click More.
  Select “Keep lines together.”

Once your style is set, you then either create a new paragraph style or you redefine the existing paragraph style to reflect the changes you just made.


No rush. If you're having a smooth experience with OS 4 for now, keep using that OS and wait a few updates... the first version (in this case 5.0) always has a few bumps. I know I have!

But if you need any one of the new gadgets (like iCloud, or iMessage), then you can switch anytime. Just make sure you do a full sync before with your iTunes (the one the iPod has always been synched to) and do a restore, not an update. It'll clean up the whole iPod and start fresh, then sync your personal data. Installing a fresh OS from time to time really does help... :-)


A good way to run classic Mac OS 9 applications on modern computers is to run the SheepShaver Emulator. I'm assuming that since your mac says the Classic Environment is no longer supported, you are trying to run a Mac OS 9 or below app.

ROM files and classic disc images are easy enough to find online, but I won't link you any just in case it is against copyright regulations.


(Note, 1) I have my Alfred preferences located on my dropbox, but the default location is at ~/Library/Application Support/Alfred 2, i.e., in your home folder's Library folder, and 2) the following is for the Alfred 2 app)

Using sudo opensnoop | grep Alfred.alfredpreferences in terminal (if using this you'll need to provide your admin password), I see that adding a custom web search updates the following file within the Alfred.alfredpreferences.

Alfred.alfredpreferences/preferences/features/websearch/prefs.plist in the Finder.

You'll need to right-click on the Alfred.alfredpreferences file to "Show Package Contents" to view these folders.

Once you've navigated to the .plist file, it can be view via Quicklook by pressing the Space Bar whist the file is highlighted.


Why do duplicates keep showing up in my address book?

This will most likely be from contacts duplicated on the two servers - turn off the contact service on one of the servers and you should see your dupes disappear. We had this same issue recently when migrating from an in-house Exchange server to Office 365. Various users had contacts set up on both and were complaining about having duplicates in their contacts lists. Our policy is to leave contacts stored on iCloud but you may have different priorities.


Podcast cover art missing since upgrading to iOS 5

I was able to fix this myself in the end by deleting the podcasts on the iPhone itself and then re-syncing. Sometimes it took several attempts before the cover art came back.


macOS High Sierra: still usable as a development environment?

This is not a critical problem. You should be able to continue developing on your MacBook Pro for a year or two yet.

iOS Development

For iOS development, so long as Xcode supports your operating system, there is no problem. Do check the iOS SDKs supported by Xcode in case you need to work with specific features.

macOS Testing

You will be able to continue developing applications that target macOS 10.13 and below. Building for macOS 10.14+ is possible but testing will be a problem.

Some features, such as Dark Mode/Appearance support, will be difficult to implement correctly. Implementing support does not require the developer run macOS 10.14, but they should be able to borrow or test on a Mac running macOS 10.14.

App Store Submissions

You will continue to be able to submit applications to Apple's App Stores. Historically, Apple have not restricted what tools or versions are used to build applications they accept.

Future

Be aware that Apple previewed an iOS on macOS framework at WWDC 2018. This suggests significant changes are coming to at least the Mac platform. You may want to wait until more is known, before investing too much in a new Mac.


How can you mark every item in Safari's reading list as "read"?

The XML tag that determines whether the article has been read is DateLastViewed.

I think the simplest, most user friendly way to do it (for most people, anyway) is with TextEdit find-and-replace.

First, though, you're going to have to convert the plist file from binary to XML with this command (Enter it at the prompt in /Applications/Utilities/Terminal.app): plutil -convert xml1 'Library/Safari/Bookmarks.plist'; open 'Library/Safari/Bookmarks.plist' -a TextEdit Don't worry if it gives you an error; that just means it has already been converted.
The command will also open up the newly converted file in TextEdit.

Find-and-replace

<key>DateAdded</key>
 with
<key>DateLastFetched</key><date>2012-10-13T12:15:04Z</date><key>DateLastViewed</key><date>2012-10-13T12:15:04Z</date><key>DateAdded</key>

What this does is puts the DateLastViewed (and DateLastFetched, just to be safe) before every time it finds a DateAdded. I don't know if it actually uses the dates for anything, but you can change them if you want.

Can an iOS app that has access to Photos get all my photos?

Yes, if you give the application access to your photos and the application has network access, the photos can be taken from your iPhone.

Only use apps you trust

If you do not trust the developer, do not install or use their applications.
If the developer is not clear and explicit about how they handle your photos, do not install or use their applications.
If the developer is not contactable or does not answer your questions, do not install or use their applications.


Can't boot from USB or reset PRAM/NVRAM on mid-2006 iMac

It sounds like your keyboard may have been the culprit. (From the comments)

Using a different wired keyboard can be a good troubleshooting step for iMacs.


Backing up home directory, can I exclude ~/Library?

The Library folder contains all the preferences set for the applications you are using, login information for Mail etc, the local mail archive, your keychain and a lot of other configuration stuff. If you are using iCloud Drive it also contains the local copy of the drive content; and backups of your iDevices in case you don‘t use iCloud backup for them.
You may be able to recover most of it in case of data loss, but some things (e.g. your keychain or any locally stored mail) will be lost.
Given that external drives and USB sticks are rather cheap nowawdays it's most probably not worth the pain to fine-tune a backup script to include just the essentials from ~/Library.


How can I run Apple Hardware Test with a firmware password set?

How to reset ACLs after Apple Server sharing mistake?

Everything is fine and the ACL repair is working as it should. Take the first two lines of the output:

ACL missing on 'System/Library/User Template/ro.lproj/Library'.
Repaired "System/Library/User Template/ro.lproj/Library".

The first line is logged when an incorrect ACL has been found. The second line is logged when the repair is a success. If the ACL couldn't be repaired, this second line would say something different. Everything is good!


Where is the history of "Go to Folder..."(in Go menu of Finder) located?

Is a hardware-based full disk encryption possible on a Mac?

I've asked myself exactly the same thing as I've also bough a Samsung 840 Pro for my MacBook Pro. After some research I've found this post indicating that the 840 Pro's hardware encryption requires TPM support, and that's only found in PC BIOSes, not in Mac's (U)EFI. To be sure, I've asked Samsung support which of the standards "ATA-Security", "Seagate DriveTrust" and "TCG OPAL" are supported by the 840 Pro, and their answer was:

  Dear Customer,

  Thank you for contacting Samsung SSD support regarding your inquiry.
  In response to your inquiry, the only one of the 3 that the unit
  supports is the ATA Security feaure. As for the encryption, the 840
  Pro Series SSD only supports AES 256 bit hardware level encryption but
  requires the BIOS to be TPM enabled.

So there's no way to enable the 840 Pro's hardware encryption in a Mac.

However, there's also the Crucial M500 which supports TCG's Opal. In conjunction with a special Opal management software like WinMagic's SecureDoc for Mac it sounds as if it's possible to get hardware encryption to work on a Mac.

BTW, note that according to Sophos' support their SafeGuard does support Opal only on Windows, not on Mac OS. Also, McAfee's General Q&A for Opal states

  Q: Will Opal drives be supported on Mac OS X?

  A: No. Apple currently does not ship their devices with Opal drives so Opal is not supported on Endpoint Encryption for Mac.

But of course that's says nothing about that happens if you just put an Opal drive into a Mac yourself.


Just an idea: maybe try making an image of the Windows partition with WinClone and then try to restore it - it will offer to recreate the "boot files" - if I remember correctly. Maybe there is a shorter way, this experiment will take a few hours... like I said, just an idea, double check if WinClone really offers to recreate the boot files.


What happens if I create a file while Time Machine is backing up?

Is there a way to rescue the contents of this messed up Fusion Drive?

Ok so I did a test before I tried it with the actual affected drive. I had an old 60 GB laptop spinning hard drive, and a 32 GB laptop-form-factor Corsair SSD, which I made into a Fusion Drive.
I first formatted each drive and did a secure erase in the process to make sure there were no retrievable files left on the drives. Then used the appropriate diskutil command to make the two into a 92 GB Fusion drive.

Then I copied my 76 GB Photos Library over to this drive, which will make sure there have to be files on both drives. Then left it to "simmer" for a while (i.e. left some time for Core Storage to move files and file blocks around), maybe 1 hour. Then I opened Photos with that library, deleted, duplicated and modified a few photos, maybe 10 or so, over about 15 minutes.

I know this is not a perfect representation of real world usage of a Fusion Drive over a long time, but I feel it would give me a reasonable true idea of the rescue potential of the files in a similar Fusion Drive setup.

Then the test: I properly unmount the Fusion Drive, then plug only the spinning hard drive back in. This replicates the problem with the iMac am I having, where the internal SSD went offline.
Now running the diskutil corestorage list command I see the exact same as I did with the iMac: the logical volume is there, but one of the physical disk is listed with no properties to show for it.

I then issue the diskutil cs delete command with the UUID of the logical volume (i.e.the Fusion Drive). It looks like diskutil is formatting the spinning hard drive as a normal HFS+ GUID partition disk, and after it's done the spinning hard drive appears on the desktop, seemingly empty, as you would expect.

Running Disk Rescue 4 on this disk with a Deep Scan shows me the the file rescue potential of this scenario is actually very good. DR4 is able to restore file names and folder structure of approximately 80% of the files and I end of with about 56 GB worth of images.

After this test I basically do the same with the actual iMac that I was tasked with, and I had pretty similar file rescue results with that internal 1 TB spinning hard drive.

Open a new Chrome window in Incognito mode from terminal

Use something like:

open -a "Google Chrome" --args --incognito "https://en.wikipedia.org/wiki/Main_Page"

Google Chrome accepts --incognito as a command-line option.  To pass that option to the application via open, specify it after the --args flag.

If Chrome isn't already open (since this was not specified whether the original questioner needed to launch it fresh or if it was already running), -n is also needed to start a fresh instance.

In general, man open is your friend.


Backup, share, or save iPhone voicemail messages?

I believe there are applications that can extract the voice messages from your phone but they cost money and required the phone be plugged in to the computer.

The simplest way is to connect your phone to your computer with a 3.5mm audio cable. Use a simple audio recording app, such as Audacity, click record and play the voice message.


I can't find the location of jdk for Java 7 and 8

You can see the install locations of the recognized JDKs by using java_home's "-V" option:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (4):
    1.8.0_31, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home

    1.6.0_65-b14-466.1, i386:   "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

You see newer JDKs are under /Library/Java/JavaVirtualMachines. I think it was moved out of "System" after Apple stopped developing the OSK JDK themselves and Oracle took over.

Also see /usr/libexec/java_home --help for more options.

What's the simplest way to process files with UTF-8 characters in groff on macOS?

As of today, macOS Mojave ships with a quite outdated version of groff (1.19 or something...) which apparently cannot handle the -K option. Thus it fails to recognise any fancy diacritics (german umlauts in my case), if you run groff -Kutf8 ....

You can get a newer version of groff on macOS by installing it via Homebrew, as per this post

brew install groff gs

(not sure if gs for ghostscript is actually required; I installed it anyway)

No bootable device found ( Install windows on Mac )

The problem is that your MacBook doesn't have BIOS, it uses EFI instead. I won't go into the differences between the two, but the Boot record you've created on your USB is for BIOS not EFI.

There are two fix this, one requires a PC with Windows, the other doesn't.

Windows method:
Go to this link: http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.html

It'll explain the steps you need to follow to have your MBP boot from the USB.

Other method:
Go to http://gparted.org
Download and run GPARTED
Convert your MBR volume to GPT

Now you're EFI will recognise your USB as a bootable device :)


There is no easy way to select all the Hyperlinks all at once, but what you can do is use the Styles Drawer to create a custom Style so that you can apply it very quickly to you hyperlinks.

To use the Styles Drawer to create a custom style follow these steps:

In the Pages menu bar click on View > Show Styles Drawer.
Highlight the Hyperlink with the correct color.
Under the Character Styles click on the dropdown arrow and select "Create New Character Style from Selection"
Name the Style accordingly.
After that click on any hyperlink in which you would like to apply the style and click on the style.
