Can the 12-inch macbook charge from USB-A?

Can a Macbook charge it's batteries from a USB-A charger (car or wall) or battery pack?

It depends, but yes, it should work.  The charging performance may vary from it charges very slowly to not at all.

"Type A" is the connector type; it has nothing to do with how much power is being delivered.  What you need is a power adapter that is compliant to USB 3.1 specifications.  It just so happens that to connect it to your MacBook, you need a "Type C" connector.

Would I recommend you doing this?  Absolutely not.

Important Note:  Plugging into a power source that is significantly lower than what is required by your device can and will damage your equipment.

Why?

First, we need to know what the power requirements are to power the Macbook; per Apple, it requires a 29W USB-C Power Adapter (see below).

Generally speaking, the USB Type A adapters most people are familiar with are those that charge their iDevices.  These are based on USB 2.0 at best and according to the specifications, they are limited to 5V 1.5A.

That means, those chargers are limited to 7.5W. (Watts = Volts * Amps) 7.5W  is nowhere enough to power your Macbook.

If you notice in the above USB 3.0 pin out diagram, there is only 1 5V (VCC) pin (this is important in understanding USB 3.1 further down).

The USB 3.1 is the specification that says it will support up to 20V at 5A.  Using the same equation from above we get a specification that is capable of handling up to 100W so there's enough power "bandwidth" to charge your Macbook.  But that's using a special communications protocol over a USB-C cable.

20V * 5A = 100W

However, the basic spec is still the same, 5V but now at 3A and there are two 5 volt pins as opposed to only one for USB 3.0 and earlier.  This means combined you can get 10V.

If you notice in this pin out diagram there are two 5V pins (Vbus).  These are combined to make 10V.

Note:   There are some USB 3.1 Type A adapters out in the wild, but they are so few and far between I wasn't able to find a schematic for the pinouts.  I am using Type C since these are the most common.

So using our trusty equation again,

(2x 5V) * 3A = 10V * 3A = 30W

30W is within spec of charging your Macbook.

But what about the cable?  Plugging in a USB 3.1 (A to C) into a non-USB 3.1 power adapter will not fix the problem.  The adapter is only providing 5 volts on one pin, not on two that's required to get the appropriate amount of current.


A1502 Late 2013 MacBook Pro will not boot, one exception

Good news, after a couple of months I FINALLY figured out the problem. After watching a Louis Rossmann video, I saw something about jtag connectors. I removed the jtag connector and the fans now spin. Along with that, it says the battery is low on the screen.

I'm assuming something at apple was able to turn it on. But now without the jtag connector it actually is working.


No - I'm not getting it and can't seem to break things even trying to.

An official bug might be warranted as you seem to have been careful to be sure it's happening. I would be very certain to file if you can make a new account and the same happens in a clean calendar.


The install CDs took a lot of shortcuts to deal with read-only boot volumes. One of the tricks is to mount the swap partition in a ramdisk - yes, it sounds rather pointless to swap your RAM to another part of memory, but I expect it was easier to do that than to rewrite the kernel to not swap at all. Make the GUI single-application and you won't need swap anyway.

If you are making a maintenance drive rather than a one-task USB installer I would recommend a spinning external. Faster than most USB thumb drives and it will have enough space to recover data. Get a 500Gb external, partition it into a 50Gb boot volume with CCC, DiskWarrior, DataRescue and whatever else you like, a standard recovery partition, and the rest for user data.


I may have found a workaround, rather than a solution...

I kept iTunes 12.6.3 & did the iOS 11.3 update OTA.
iTunes can still sync/backup & still keeps the older apps features operable.

I imagine this workaround will fail the first time I need to set up a new iDevice or restore from a backup.


Google Authenticator stores data in the Keychain and does not include such data in backups. You cannot recover your generators from a backup because they are not stored in the backup in the first place. You will need to perform the 2FA recovery steps for each service you no longer have access the 2FA to.


Can I delete /System folders in Time Machine backups to save space?

You can certainly do this. I would first set Time Machine to exclude the system folder and then get a back up or two intervals.

Then you can browse the current backup and step back in time. Once you see a folder show up - control click (right click) and delete all versions of the affected folders.

In practice, system changes are very low and small - so you might only save 20 GB or so. Applications might save a little more space, but you can do what you want.

I generally just set my drive on the shelf and get another $100 drive and start over. Much easier than squeezing the last few GB from a full drive - but if you back up to a network volume - cloning that to an external drive takes quite some time in practice. That's also a nice option if you can spend the time and then start over. Be sure to test restoring a file before you delete anything you might care to not lose.


Kindle for Mac is specifically for reading Kindle books, and doesn't handle any other media.  On iOS, the same is available through the Kindle app.

Amazon Cloud Player for Mac is for music purchased in the MP3 store.  Again, there is an Amazon Cloud Player app for iOS as well.

On your Mac, Amazon Instant Video is available through the Amazon website itself.  If you have video in your library, you can access it through Your Video Library.  In general, though, any video you have rights to view (e.g. with Prime Instant Video), you can access by finding it on Amazon's website.  On iOS devices, you can use the Amazon Instant Video app, which also supports AirPlay for playback on an Apple TV (though Amazon does not actually have native video support on Apple TV.)


iPhone "un-downloading" photos in Messages

When you have iMessage iCloud Syncing enabled (this switch is located in iCloud settings, as opposed to iMessage settings, your device will remove downloads since they're stored in your iCloud account. This is done to keep your local storage space available.
If you turn off this feature, your phone will probably download your messages. However, if you don't have enough space I do not know what solution it will propose.
In theory, if you have sufficient space, iMessage iCloud Syncing will not remove your local file downloads.

How can I unpack a .deb on Mac OS X without installing it?

ar is already installed on my mac on OS X. So just do

that's it. No need to install other software.


How do I make iTunes sync automatically when an iPhone, iPad or iPod is connected?

Your list holds the answer, specifically #4. The problem is the fact that when iTunes it prevented from automatically opening when a device is connected, there's a whole list of actions that simply don't happen, sync triggering is one of them.

Re-enable 'Open iTunes when this iPhone/iPad is connected' and your syncs should work normally, and automatically, again.


Can an iPhone 5S play music that's stored on a USB drive?

You can read a flash from an iOS device, but this capability is limited to some very fancy lightning-port enabled USB flash drives.

For most use cases, I would recommend using a cloud service like Google Drive if you're looking to listen to purchased music on an iPhone without using up storage space. Essentially, you can just drag your music purchased from anywhere into Google Drive, download the app onto your iPhone, sign into your account, and listen to your music (though you of course need an internet connection unless you download them to your phone).

However, if you want to buy a special flash drive, you can purchase the Sandisk iXpand Flash Drive, which plugs directly into the lightning port and can play music while plugged into the iPhone, through the Sandisk iXpand app. Just connect it to a Mac/PC beforehand to load music onto it through the standard USB port.

tl;dr: Buy this flash drive or use Google Drive.

Edit: don't forget about streaming services like Spotify and Apple Music, which don't take up storage space either.


Flush cache of DNS on macOS Sierra & High Sierra

sudo dscacheutil -flushcache does nothing useful related to DNS cache entries - at least in non-LDAP environments and 10.9-10.13.

sudo killall -HUP mDNSResponder sends a hang up to mDNSResponder, launchd will restart the daemon and the DNS cache will be cleared as spillover effect.

This can easily be tested with the following command sequence:

sudo killall -INFO mDNSResponder

  default    03:54:55.672826 +0200   mDNSResponder   Cache size 282 entities; 189 in use (73 group, 29 multicast, 87 unicast); 2 referenced by active questions
  default    03:54:55.694219 +0200   mDNSResponder   Unicast Cache size              1769

sudo dscacheutil -flushcache
sudo killall -INFO mDNSResponder

  default    03:55:52.148629 +0200   mDNSResponder   Cache size 282 entities; 180 in use (79 group, 19 multicast, 82 unicast); 2 referenced by active questions
  default    03:55:52.157180 +0200   mDNSResponder   Unicast Cache size              1992

sudo killall -HUP mDNSResponder
sudo killall -INFO mDNSResponder

  default    03:56:39.446829 +0200   mDNSResponder   Cache size 282 entities; 8 in use (4 group, 0 multicast, 4 unicast); 2 referenced by active questions
  default    03:56:39.466259 +0200   mDNSResponder   Unicast Cache size              121

To get the results above open Console.app, choose your hostname in "Devices" and use a filter mDNSResponder & Cache size:

MacBook Pro M1 external display connection issue

Numerous people report issues with ultra wide screens (width > 2*height) and M1 Macs. By my count, there have been three questions here in the past week.  There are 12 pages in this macrumors thread.
I suggest a web search for "Mac m1 ultrawide" to get a feel for the number of problems.
Apple have acknowledged the issue, but are yet to provide a fix. For a report on this 9to5Mac.
To reduce the number of uncertainties, try and get the monitor to work without any dock.  When that fails, contact Apple.
I am aware that this "answer" does nothing to resolve problems with utrawides, it is little more than a pointer to it being a widespread issue.


Can Keynote on iOS play PowerPoint files with audio?

These files will no longer appear in the Music library. To see them again, open the Books library.


Can you change the storage location of Conversation History for Mac Lync?

How about moving that directory to Drop Box, or a similar cloud-synced space, and then symlinked that path to your cloud directory?

You can create the link with the Finder 'Make Alias' command under File, or use Terminal to create a link with 'ln'.

The original directory goes in your cloud directory, and the alias goes back in /Users//Documents/Microsoft User Data/

This process is standard for DropBox, I assume it would work with other services too.

Is it true that an expedited review in the app store is not allowed for more than one application?

I don't think there's an automated system, I once requested two expedited reviews in a row (due to my own improper testing), and got both accepted.

So no, no firm rule, but they'll probably look at your history when deciding, and your reason for asking for an expedited review.


Convert document to PDF from right-click context menu

I don't know any app like that. You can simply to convert any .doc to .pdf over the internet, on several websites.


The first thing to do is backup your data, although if you were migrating from the PC to the Mac, then you've probably already got an original copy there anyway.

If you have a backup, then probably the easiest thing to do is create a bootable external drive, boot your Mac up from that, and then delete files from the internal drive.

If you have an external USB hard drive, you can start up from macOS Recovery to format it and install macOS. More specifically, you have the following macOS Recovery options:

commandR to reinstall the latest macOS that was installed on your Mac, without upgrading to a later version
optioncommandR to upgrade to the latest macOS that is compatible with your Mac
shiftoptioncommandR to reinstall the macOS that came with your Mac, or the version closest to it that is still available

Broadly speaking, follow these steps:

Boot up into macOS Recovery using one of the options above
Use the Disk Utility option to erase/format the external USB drive (NOTE: This means you will lose all data on it. Another option is to use a USB Thumb Drive of at least 8GB in size, although this will probably be a lot slower).
Once it's formatted, install macOS. (This will take a while).
Once complete, boot up from the external drive by holding the option key during startup and then selecting it to boot off.
Once booted up into macOS from your external drive, your Mac's internal drive should be accessible as if it's an external drive.
Delete files from the internal drive. (Note: You will want to ensure you have at least about 9GB of free space in order for macOS to function properly. However, my recommendation is that you generally was to have no less than about 15% of your drive's capacity free).
Make sure you don't forget to empty the Trash (Finder > Empty Trash...)
When you've freed up enough space, go to Apple > System Preferences > Startup Disk and make sure you've selected the internal drive as your startup disk
Shut Down your Mac (Apple > Shut Down...)

Barring any other issues, you should now be able to boot up from your internal drive.


How to remove old epson software from iMac?

The solution that worked (for other users):

Follow the instructions here:

  From the Apple menu, select System  Preferences.
  Click Print & Fax.
  Highlight any Epson printers and click the ￼ button to remove them from the Printers list, then click OK.
  Open the hard drive

  Select Library > Printers.
  Select the folder labeled EPSON and drag it to the trash.

  Note: This will remove all installed Epson printer drivers. You’ll
  need to reinstall any printer drivers that you still need.

If the software is still on your computer then try using the uninstaller.

This should completely remove all the software.

Parrot OS does not come with all the drivers necessary to run on a MacBook Pro 2017. You will have to use an external mouse and keyboard to manually install the drivers.

First some extra packages:

sudo apt install git kernel-devel dkms

Next we need to prepare for the modules to be included in the ramdisk (so they are loaded early during boot):

cat <<EOF | sudo tee /etc/dracut.conf.d/keyboard.conf
# load all drivers needed for the keyboard+touchpad
add_drivers+="applespi intel_lpss_pci spi_pxa2xx_platform apple-ib-tb"
EOF

Now get and build the drivers:

git clone https://github.com/roadrunner2/macbook12-spi-driver.git
pushd macbook12-spi-driver
git checkout touchbar-driver-hid-driver
sudo ln -s `pwd` /usr/src/applespi-0.1
sudo dkms install applespi/0.1
popd

Next we need to set the proper dpi for the touchpad and adjust the sensitivity (download the 61-evdev-local.hwdb, 61-libinput-local.hwdb, and local-overrides.quirks from this gist - the 61-evdev-local.hwdb is only needed for udev < 242, the 61-libinput-local.hwdb is needed for libinput versions < 1.12, the local-overrides.quirks for libinput versions >= 1.12):

# if 'udevadm --version' less than 242:
sudo cp ...the-downloaded-61-evdev-local.hwdb... /etc/udev/hwdb.d/61-evdev-local.hwdb
# if 'libinput --version' less than 1.12:
sudo cp ...the-downloaded-61-libinput-local.hwdb... /etc/udev/hwdb.d/61-libinput-local.hwdb
# if 'libinput --version' 1.12 or later:
sudo cp ...the-downloaded-local-overrides.quirks... /etc/libinput/local-overrides.quirks
sudo systemd-hwdb update

You can test the drivers by loading them and their dependencies:

sudo modprobe intel_lpss_pci spi_pxa2xx_platform applespi apple-ib-tb

Finally, reboot to make sure it all works correctly:

sudo reboot

iPhone SE problems on 11.0: apps freezing and voice call problems

You should backup your iPhone SE with iCloud backup.
Then restore it to factory by using iTunes on a computer (Mac or PC/Windows). This will erase the entire phone (hence why a backup is recommended 1st) then it will install iOS 11 with a fresh install. Not with layers of patches, which is what you currently have). After the restore is done, and the iPhone says hello, then you can set up the iPhone and then restore from iCloud backup. That should help with the software problems.

As for the calling aspect, if it pops up again, remove and re-insert your SIM card tray into the iPhone (right hand side of the phone). If the issue persists afterwards, reset all settings.


macOS overall slow UI when running (Adobe?) apps

okay, today I tried to solve this with a hint from the Adobe forums: some people said the performance gets significantly better when using the colour profile "apple RGB" for all attached monitors (instead of using "iMac" or some real colour profile from a calibration tool).
and indeed, that worked, I can now have InDesign or acrobat open and still use a browser or finder or text editor without spinning wheels. this seems to be Catalina+cc2020 only, every other combination seems to work with profiles.
it's no real solution as I need profiling and color management, but at least I've found the cause.
Who is the culprit is hard to tell - apple changing color management methods (64bit? other layer in the display stack?) or Adobe not able to cope with it after now 8 months of CC2020 on Catalina ...

TL;DR    Under macOS Catalina, to remove the sleepimage file using Terminal while booted normally to your Desktop, use the following command:
sudo pmset hibernatemode 0

Tested under a macOS Catalina (10.15.6) system, without FileVault, the following was all that was necessary to remove the sleepimage file, typically located at: /var/vm/sleepimage
Note that this was done in a normal mode boot and booting to macOS Recovery and disabling System Integrity Protection was not needed. Even if booted to macOS Recovery, one does not need to disable System Integrity Protection in order to delete the sleepimage file from there.
Booted to my normal Desktop, in Terminal I ran the following commands to show it can be done as advertised:
~ % pmset -g | grep 'hibernatefile\|hibernatemode'
 hibernatemode        3
 hibernatefile        /var/vm/sleepimage
~ % ls /var/vm/
kernelcore  sleepimage
~ % sudo pmset hibernatemode 0
Password:
~ % ls /var/vm/
kernelcore
~ %

Setting hibernatemode to 0 automatically removed the sleepimage file.
Setting hibernatemode back to 3 recreated the sleepimage file.

Notes:

The system I used did not have FileVault enabled, however, I doubt it would make any difference if it did.
Tested under normal mode boot in macOS High Sierra after using sudo pmset hibernatemode 0, I had to manually delete the sleepimage file using: sudo rm /var/vm/sleepimage
Did not test under macOS Mojave, however, one of the methods used under macOS High Sierra or macOS Catalina should work.

To remove the sleepimage file from macOS Recovery in macOS Catalina 10.15.6, without FileVault, I tested the following without disabling System Integrity Protection.

Booted to macOS Recovery
Opened Terminal from the Utilities menu.
Ran diskutil list to ascertain which disk was APFS Volume VM. It was: disk1s4
mkdir /Volumes/VM
diskutil mount -mountPoint '/Volumes/VM' disk1s4
rm /Volumes/VM/sleepimage
diskutil unmount '/Volumes/VM'
reboot

Note: This was included just to show doing the SIP Dance is not necessary under macOS Catalina, just remove it from a normal mode boot.

Archive utility hangs at 5 seconds remaining

Anything interesting in the console app (system.log or other activity)? Any chance you accessed any of these files from another app? Mail.app is notorious for never "closing" attachment files, so you might need to close the apps that might have the files open. It's hard to know what's causing it without attaching a debugger to the process and seeing where in the code is working or waiting.

If there isn't a lot of other activity - (i.e. quit every app you can - maybe all of them if possible) and then use fs_usage to see what file activity is ongoing from the command line/terminal.app:

sudo fs_usage -w

The other avenue is a split half search. Kill the hung process and compress half the folder at a time, narrowing down to a specific file that's causing compression issues. It might just be bad luck and the next time you try to compress all will be well.


How to delete "invisible" files/folders (device backups)

The fact that the copy was instant would lead me to believe that the source drive and destination drive are the same. So I'm guessing that the Backup folder is actually somewhere on the MBP drive.

You could open terminal and do something like

sudo find ~ -name "3d0d7e5fb2ce288813306e4d4636395e047a3d28"

That would search your home folder for the backup file for the sms database. I just picked a random backup file that everyone should have :) as a way of looking for iTunes backups. I limited to the home folder try to speed up the search, but you could do

sudo find / -name "3d0d7e5fb2ce288813306e4d4636395e047a3d28"

and walk away and give it some time. Or keep subbing out different search locations like /Library, etc.

Future compatibility note: The different file permissions in macOS Mojave would likely prevent this from working. But in El Cap I think it should work.


There are a bunch of posts online from users who have run into this issue. All of them end with the same answer: "I hope you have a backup."

I have spoken to multiple people who have worked with Unix/Linux for a long, long time. The general consensus is that

there is no way to just "turn a folder into a file"
there is no recovering from whatever you have done without restoring the
directory from a backup

They believe that some application has deleted the directory unintentionally and replaced it with a file. I have looked online for a way to manually set the d bit of the file you are speaking of but there seems to be no way of achieving this.

So, my answer is to restore the directory from a Time Machine backup (you hinted that you already had a backup - use it).


can new Macbook of apple supports simultaneous charging & data transfer through usb type C port?

I'm not exactly sure what you intend to do, but at the most basic level the answer to your question is yes.

The Thunderbolt 3 (USB-C) ports on the 2016 and 2017 MacBook Pros can simultaneously support charging and data transfer. However, this will be dependent on the cables/adapters/hubs/docks etc being used. If they support/allow both charging and data transfer then you should have no problems.

In summary, the Thunderbolt 3 (USB-C) ports support each of the following:

Charging
DisplayPort
Thunderbolt (up to 40 Gbps)
USB 3.1 Gen 2 (up to 10 Gbps)

[UPDATE]

If you're after independent verification that multiple features are supported simultaneously, then refer to Using USB-C and Thunderbolt 3 (USB-C) ports and adapters on your Mac notebook. You'll notice, for example, that under the heading USB-C Digital AV Multiport Adapter it states:

  The USB-C Digital AV Multiport Adapter allows you to simultaneously:

  Charge your Mac.
  Connect to other standard USB (USB-A) devices or hubs.
  Connect your Mac to external HDMI video devices such as a TV, projector, or display.

NOTE: Bold emphasis mine.

Now, as I mentioned previously, a lot gets down to what is supported by the individual cable, adapter, etc. For example, even about its USB-C Digital AV Multiport Adapter, Apple says that:

The USB-A port on the adapter supports data transfer at up to 5 Gbps (USB 3.1 Gen 1) and can be used to connect standard USB devices or hubs.
The USB-C port on the adapter charges your computer, but it doesn't transfer data.

Note how the USB-A port on this adapter only supports speeds of up to 5 Gbps, while the MBP supports USB speeds up to 10 Gbps. Also note how USB-C port on this particular adapter is limited to only charging. However, the USB-C port on the MBP is not limited in this way, because the USB-C Digital AV Multiport Adapter connects to it and then provides simultaneous functionality to all three of its ports for charging, USB-A devices and HDMI devices.

Now, depending on your specific model of MacBook Pro (you don't specify), the data transfer speeds may vary depending on the port used. More specifically:

  Thunderbolt 3 data speeds per MacBook Pro port

  MacBook Pro models introduced in 2016 vary slightly in the data speeds
  they provide to each Thunderbolt 3 port:

  MacBook Pro (15-inch, 2016) delivers full Thunderbolt 3 performance on all four ports.
  MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) supports Thunderbolt 3 at full performance using the two left-hand ports. The
  two right-hand ports deliver Thunderbolt 3 functionality, but have
  reduced PCI Express bandwidth.
  Always plug higher-performance devices into the left-hand ports on MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) for maximum data
  throughput.
  MacBook Pro (13-inch, 2016, Two Thunderbolt 3 Ports) delivers full Thunderbolt 3 performance on both ports.

  About USB speed

  For USB devices, all 2016 MacBook Pro models deliver USB 3.1 Gen 2 (10
  Gbps) performance on all Thunderbolt 3 ports.

  Use a USB-C to USB adapter to connect a USB-A device or cable to a
  Thunderbolt 3 port on your MacBook Pro. Use a USB 3.1 (USB-C to USB-C)
  cable to connect a USB-C device.

The screen is called Launchpad and is a feature built-into macOS. First introduced in Mac OS X Lion 10.7, it displays a grid of icons corresponding to installed apps. This feature was originally inspired from iOS which displays a similar grid of icons for installed apps.

This gesture is pre-defined for Trackpad, and can be turned on/off under System Preferences → Trackpad → More Gestures

There are other easy ways to invoke Launchpad too, which can be helpful on Macs without a Trackpad:

Keyboard: Press the special F4 key on your MacBook's built-in keyboard, or Apple keyboard. On newer hardware introduced after Mac OS X Lion was released, the key shows two rows of three squares to represent Launchpad.

Dock: Use the Launchpad icon in the Dock. The icon for the app is present by default in the Dock and looks like this:

Spotlight: Launchpad can also be invoked via Spotlight search:

Applications: Launchpad is available just like other built-in apps and can be found in /Applications directory in Finder. To invoke, double click on the app icon in Finder.

To learn more about Launchpad, go through the linked Apple Support articles:

Lock Screen Notifications Without Content?

Specifically for SMS/iMessage...

Settings > Notifications > Messages ... 'Show Previews'

That option doesn't exist for Facebook, though as I don't allow Facebook to push notify my phone I'm not sure what options there may be in the app itself.


When I'm texting, sometimes the receiver's email shows up

Those emails are from iMessage, as you can receive iMessages with both your email and phone number. If the messages are colored blue, it is iMessage.

How to create a custom keyboard shortcut for this nested menu item?

It doesn't matter that it's a command on a nested menu. Just create a proper entry, and in this case for the Right to Left command under Paragraph, it's:

'   Right to Left'

Without the single quotes and that's a leading tab space in front of Right to Left.

Note: You will need to copy and paste the '    Right to Left' (without the quotes from a text source other then this answer because AD converts tab characters to space characters), as you cannot key press a tab when creating the entry.

Here are some screenshots from my system:

Note: For the Right to Left command under Selection there are two leading tab spaces, e.g. (without the quotes):

'       Right to Left'

The quotes in both examples are there to show there is leading tab space in front of the actual command names, although note that AD converts tab characters to space characters in these examples.

Edit: this didn't help, ignore it.

This might be related to HSTS. Different browsers deal with it in different ways. Do you have any non-Apache local web server installed? I'm assuming there's something to do with Focus that's running on port 8919 from your screenshot.

Try this: Quit Safari, make a backup of ~/Library/Cookies/HSTS.plist somewhere safe, delete ~/Library/Cookies/HSTS.plist, start Safari, and try that URL again. Does that help?


How To Resume OS X El Capitan download after shutting down MacBook Air?

You can't resume the download after a shutdown. But your MacBook Air doesn't need to "rest". So start the download again and don't shut down the MacBook until it's finished, even if it takes days.


MacBook Pro restores last user session after shutdown because of low battery

You might not have understood it fully since your lid was closed.  So I will take you to an adventure to demonstrate what you would have seen if you left the lid open at the time.
Battery Low (~15%)
Around at 15% when running on battery power, the battery icon in the menu bar will turn red in order to notify you that your battery is starting to get low.

Battery Critically Low (~5%)
If you ignore the initial low battery warning and keep on using DC power, the MacBook will warn you about the "reserve battery power" when the battery drops to about 5%.  At this point, you should as soon as possible plug in your laptop into AC power.  Or else, the computer will take its own action soon.

Battery Empty (~0%)
When your battery reaches "empty" (around 0%), the computer is forced into sleep mode in order to prevent its memory contents from being destroyed or lost.

Your MacBook hit the "empty" battery level and had gone to sleep to prevent your data from being damaged.  If it did not sleep, then it would just crash-shutdown and all the unsaved data would be mass-lost.  When you plugged in and powered back on, it restored the previous session.

UPDATE:

My son plugged it in and it restarted. It asked for his password to login on his account but when he validated the credentials, instead of opening his a new session for him it reconnected him to the last active session; my session on my account.
Thanks but that doesn't explain why when logged in as user 1 and it goes on sleep, when you go back and plug it, then at the user login prompt you log with user 2 but it opens user 1 session. Huge security issue to me.
Yes multiple times but not with the latest updates. My question was asked in June.

Really?  That's extremely strange.  I've never seen a Macbook doing this before, and different user sessions shouldn't overlap each other.  If this is still happening, then I would like to suggest you to report this to the Apple company.  It seems like you are experiencing a huge security-related issue, so please call the Apple company about this immediately. It appears like your Mac could not tell the difference between his account and yours.  This is a massive problem, so please report this to Apple ASAP!

As more of a Windows user, I will also point out that in Microsoft Windows it functions in a similar method but what displays on the screen is slightly different. On Windows XP, for example, this is how it works:
Battery Low (~20%): At first, the battery indicator in the taskbar becomes less filled - barely filled with its blue juice.

Battery Critically Low (10%): When the battery reaches 10%, the indicator gets a red X mark and a notification is triggered, and the system urges the user to either replace the battery or connect to AC power immediately.

Battery Empty (3%): On XP, when the battery reaches 3% the computer will hibernate.

But as far as I know, neither Windows nor Mac should perform the action you are describing.


Just to rectify one thing: disk1 is not the encrypted data. Disk1 is a mounted "virtual" volume with its own disk identifier. This volume is unlocked and as such unencrypted if you are a legitimate user. It's based on inferior encrypted data structures residing in disk0s2.

To clone (and subsequently decrypt) FileVault2 volumes successfully three objects/data structures are important:

Superior LVM structures in disk0s2 (the CoreStorage Volume Group)
The Recovery HD partition. It contains some intermediate keys which are necessary to extract the final keys to unlock the FileVault2 volume.
The encrypted data itself

To clone a FileVault2 volume you may either dd the CoreStorage LVG and the Recovery HD or copy the unlocked FileVault2 volume to a second volume with rsync or Disk Utility/a disk cloner like Carbon Copy Cloner.

dd:

Open Terminal and enter diskutil list.
Enter sudo gpt -r -vv show /dev/diskX with diskX: the disk with the CoreStorage LVG containing the FileVault2 Logical Family/Volume
Now attach a second (external) disk (diskY) and replicate the GUID partition table of the source (diskX) to the target disk (size, type etc.) with gpt.
Recheck the identity of the GUID partition table of diskX and diskY
Enter:
dd if=/dev/rdiskXs1 of=/dev/rdiskYs1 to copy the EFI partition
dd if=/dev/rdiskXs2 of=/dev/rdiskYs2 to copy the CoreStorage LVG
dd if=/dev/rdiskXs3 of=/dev/rdiskYs3 to copy the Recovery HD
done

Disk Cloner

This will not create an identical disk (same intermediate/final keys etc.) but a volume containing identical data.

Boot to a Recovery HD, an installer thumb drive or a second full-blown OS X volume.
Enter the unlock key of the FileVault2 volume while booting.
Attach the external disk and create a sufficiently dimensioned normal volume with an appropriate tool.
Open Disk Utility (or Carbon Copy Cloner if use a full OS X system)
Restore the source volume (the unlocked FileVault2 volume) to the destination disk.
Reboot to the external drive.
Open System Preferences -> Security and enable FileVault.


How to sync up a folder in amazon S3 with people in Austria

I recommend either 3Hub or Forklift in the App Store. If that is not what you are looking for, I can also use https://github.com/timkay/aws. It is command line only though.


Safari mute tab while it isn't playing audio

I don't think you can.
Even if you add a key command, it simply doesn't respond & stays greyed-out unless there is actually audio playing. It doesn't even highlight if video is playing, if it has no sound.


Having to hold links and webpages to open them

Have you checked your settings in General > Accessibilities? For most people, most of the options should be disabled (except for shaking the screen to undo an action which is by preference).

I have a possibility. Are General > Accessibility > Touch Accommodations > Touch Accommodations + Hold Duration both turned on? Because they make it so that you have to hold on the screen in order to register a touch. That seems to fit your context because they should be off in general.


Accidental corrupted recovery mode partition and cannot longer boot to it

I solved it by creating a bootable USB macOS installer with createinstallmedia from terminal. Then I booted from it and disabled System Integrity Protection and installed Refind from there. I tried booting to Recovey HD from Refind and it worked just fine.


Are certain videos blocked by Youtube on the iPhone or is this a technical issue?

There is a syndication setting that you choose when you upload a video to youtube in the video settings page under Broadcasting and Sharing Options that allows it to be played on mobile devices or not.

MacBook Pro 15" Retina Catalina mid 2014 QuickTime issues

If the problem only occurs in one application, then it's likely to be a problem with its settings, or some system setting that controls audio per-application.

Wiping the drive and then putting all the files back using Time Machine will leave you with an identical drive.

You may want to try deleting the file at:

~/Library/Containers/com.apple.QuickTimePlayerX/Data/Library/Preferences/com.apple.QuickTimePlayerX.plist

(i.e. in the User Library.)

... and then test the problem. If that doesn't work, you may want to restore this file to keep existing preferences.


I had the same issue and finally found a fix!!

Not only did I NOT have wifi, but I didn't even have an option for "wifi" under network preferences.  When clicking the (+) under network preferences I only got options for Firewire, Ethernet, Bluetooth DUN, VPN PPPoE, and 6 to 4.

I tried a number of "fixes" including terminal commands to manually turn the airport power off and on again, deleting the existing wifi option (the one that wouldn't turn On) using the (-) button, and restarting my mac numerous times both in Mac OS and my bootcamp Windows OS.

Finally, i fixed this issue doing the following:

Restart your Mac.
upon start-up, hold down the Opt key until you see your drives.
click on the recovery drive (note: this will not affect or delete any files you currently have).
login if needed.
in the top right hand corner you will see the Wi-Fi icon (hopefully). Click the icon and then click "turn wifi Off" and then again click "turn wifi ON"
restart your Mac again and start it up normally.
recover from your near-heart attack

Please let me know if this worked.


How to copy the current text line without highlighting it?

The closest to what you are looking for is triple-click on the line and CMD+C that highlights and copy the whole line.

On certain code editors a piece of text is copied just by highlighting it.


Is there a good, non-Google Reader RSS reader for iPhone/iPod?

NetNewsWire is a good reader and syncing with Google Reader is optional.


Managing a large number of parallel iCloud accounts

iCloud is hard to manage in enterprise setting. Even with Apple's own macOS server it is hard to manage this kind of thing. A better environment would be Office365 or Google Apps. In both systems it's really easy to manage large numbers of accounts. And add content to for example contacts.

If you really want to stick to iCloud. Make an Automator action would be the solution.

Login to an account
Delete content
Upload new content
Repeat with next account

Further more I highly recommand to give feedback on this matter to Apple.


Why My Apple iPhone 5s Rebooted automatically?

Without jailbreaking / being a developer with Xcode / etc, it's not easy to find what caused a reboot. If it only occurred once, I'm more inclined to say that there's nothing wrong, but regular reboots can indicate either a software or hardware fault. If the device reboots repeatedly, try restoring the device's OS in iTunes. If the problem persists then that may indicate hardware failure.


There is never a safe upgrade. Even if millions of beta testers ran the installation script and nothing bad happened, they didn't have your system and your data. If your filesystem has errors, you can render your Mac unstartable by running any system update. Running a migration script could delete files you care about, could break your software, or could expose damage that already exists.

For those reasons you should always back up your Mac and estimate how long it would take you to wipe the Mac, re-download the installer (if you don't save a copy) and then re-run the migration. If you don't have time to do a complete restore or the copies of OS and procedure to recover, you should probably pass on the update.

If you have a backup plan that makes a bootable backup of your OS, you could simply test one of those bootable backups before letting the installation run on your Main OS - keeping the backup handy and safe.

If you don't have a bootable backup, then you might spend more time and install a clean El Capitan onto a USB hard drive and then migrate the data from your current boot drive.

Then you can use the Startup Disk system preference to choose to boot into 10.11 or 10.10 for as long as it takes to make sure your critical apps and settings are compatible with 10.11. Either way, you'll need to look over all your Apps - potentially apply updates to them or wait for vendor engineering and QA to release changes needed for 10.11.

homebrew already has changes for 10.11 but it's explicitly not supported, so there will be time and breakage anticipated on that front
zsh shouldn't be a large issue, but again - until you test your setup - who can guess...

That removes the pressure and stress of having all your eggs in one basket. I've been running 10.11 for quite some time and it's actually more stable for what I do than 10.10, but that's probably not everyone's experience.

You could always be lucky, install the 10.11.0 build with no backups and no contingency plans, but I wouldn't advise it without some prudent preparations in case your upgrade doesn't go smoothly.


Cloned and changed HDD; now almost every program crashes on startup

[ ... ]
Disregard my previous answer. I looked at the crash log again, and did a few searches and tracked down the following (source):

In a normal Crash Report there is an appended list of apps and utilities (the Binaries), which this crash report hasn't managed to capture...
That crash is happening very early in the launch and the Report is incomplete. The app is trying to use areas of unmapped memory and this can be caused by three factors: The Application or the Data (Your Library) and in rare circumstances, the OS.
So lets start by eliminating some possibilities:

Edited for your situation:

Create a new account (System Preferences -> Accounts), install Chrome, and see if you can launch it. If the application launches successfully, then it's likely your 3P apps are okay and the problem is something in the main account.


How do I pair the Apple Watch with another iPhone?

Go to Watch< Apple Watch, then click Unpair Apple Watch. When you pair Apple Watch to the second device, all the data will be transferred.

You can also erase all content and settings on the watch and when it restarts it will have no apps or data and be ready to pair with another phone.

Has Mountain Lion changed file sharing setup or permissions?

The FTP server in Mountain Lion is still there, just not part of the GUI. You can re-enable it using the following in Terminal:

sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist

To disable, do unload instead of load.

*The FTP root directory is your Users home folder.

Why won't Apple Mail open after install of OS X El Capitan 10.11? Any ideas?

I have to remove a PGP plug-in from /Library/Mail/Bundles to get the Mail App running again.

Just open Mail and immediately open Accounts, disable the accounts one by one to find out which one is causing the crash. Then delete this account completely and restart Mail. Then add the account all over again. It worked on my gmail account.


Using a dropdown menu with arrow keys in Photoshop

I am not sure if you can do this with the arrow keys but there are shortcut keys for navigating the layers box

Changing layer styles

  (with layer selected) hold down ⌥ + ⇧ (option & shift) and use the + or - keys to cycle through the various layer dropdown

Navigation of layers

  UP  ⌥ + ]

  DOWN ⌥ + [

Repositioning a selected layer

  (with layer selected) Move up a layer
  with ⌘ + ]

  (with layer selected) Move down a
  layer with  ⌘ + [

these work for me with the CS5 version of photoshop


Mounted drive does not show up on Disk Utility, Desktop, Finder Sidebar

A simple restart fixed the issue for some reason.

What are some good two factor methods for logging onto your Mac?

How about something like Knock?  http://www.knocktounlock.com
It's not exactly the same as looking up a time-dependent code, but does require the 'second factor' in order to unlock.

The neat thing is that many apps (I think Knock included) run on Bluetooth, so when you walk away from the Mac and the BT disconnects, it automatically locks up the machine.


How can I configure Mac Terminal to have color ls output?

Edit:

~/.bash_profile

or

~/.profile

and add the following line to simply enable color output via ls:

export CLICOLOR=1

To customize the coloring shown by ls you can optionally add this variable, LSCOLORS.

Examples

Default

export LSCOLORS=ExFxCxDxBxegedabagacad

You can use this if you are using a black background

export LSCOLORS=gxBxhxDxfxhxhxhxhxcxcx

If you'd like to mimic the colors of a typical Linux terminal:

export LSCOLORS=ExGxBxDxCxEgEdxbxgxcxd

Once you've add the above to either ~/.bash_profile or ~/.profile you can either logout/login or source the file in your shell, for eg:

$ . ~/.bash_profile

NOTE: If you need help in selecting colors to use you can use this online tool called LSCOLORS Generator.


Billing Information Required for App Updates

Officially, you should probably engage Apple's official App Store support to verify your account / get advice how to make things right.

https://support.apple.com/itunes
https://support.apple.com/contact

The former usually has a more direct link to App Store support and you can usually tap links on iOS as well or use the iOS support app which is a free download (but not likely to work if your account is locked)

https://itunes.apple.com/us/app/apple-support/id1130498044?mt=8

Lastly, Twitter and Facebook have official Apple Support presence if you like social media to engage, but unless your situation is covered in a knowledge base, they will steer you to official support if you need personal attention and the FAQ aren't helping you fix your error condition with your account or setup.


Attempting to fresh install Ubuntu dual boot rEFInd does not recognize live boot

Please refer to my answer to another question involving similar difficulties. The method is the exact same, except you should skip step 4 and use the Ubuntu ISO instead.

Before attempting anything though, remove all traces of your previous failed installation attempts from the Mac.


How to transfer/copy Notes from one iDevice to another without using restore method?

Tap the circles for your target Notes, then Move To ..., and the destination.

All done.


Finder view like FTP clients - two columns

No dual mode in OS X Finder

There is no native dual mode in OS X Finder. You can replace Finder with software like 'TotalFinder' (image below). Or you can use window managing software, like ShiftIt or mjolnir, to place your Finder windows side-by-side.

Mjolnir (donation ware) is highly scriptable and should be capable of doing exactly this.

This feature is requested lots of times, but for now we are stuck with the classic Finder as we know it. Besides tabs, the only view options we have are:

Command1 - icons
Command2 - list
Command3 - columns
Command4 - Cover Flow

TotalFinder, dual mode:


Windowing system on El Capitan, and XQuartz

XQuartz is a windowing system on its own, just installing it doesn't change anything. If you need to run application requiring X11/XQuartz, you need to start the Xquartz app (aka X11 server) before you start the application. The X11 server will then run "on top" of OS X, so the behaviour of other applications doesn't change.

See also What is XQuartz? for more details.


How can I change the default 1 hour duration of a new appointment in the iOS calendar?

add a recurring appointment for 30 minutes starting at 9 A.M. on the 28th of every month

change the title to review finances


Is there an easier way to purchase commercial ringtones and use them on an iPhone 4?

The trick should lie in converting your file to the appropriate format and renaming it so that it appears to be a regular ringtone file. (e.g. create an M4A file and change its extension from .m4a to .m4r). The top three links on a Google search are good tutorials if you like step-by-step instructions: https://www.google.es/search?rls=en&q=%22ringtone%22+%22iphone%22+%22m4r%22

BTW, you can sync your iPhone over the air. Connect it to iTunes and look for the option "Sync with this iPhone over WiFi", first screen of the Summary/Info/Apps/Tones/Music/Movies/TV Shows/iTunes U/Books/Photos lineup.


RAM Caching - Exploiting RAM to the fullest extent possible

Manually tuning RAM usage is not always as smart as it seems.

Apple have spent quite a lot of time making OS X use memory as efficiently as possible, and so even when you are not using it directly, the OS will be using it as a file cache or for keeping data ready in anticipation of future use.

If you artificially limit the amount of RAM that is available to the OS by fixing some of the RAM as a RAMdisk, then you are not allowing the OS to work as efficiently as it can - and in fact could be constraining the memory available when it needs it, for a RAMdisk that might not be necessary at that time.

The OS tunes RAM usage constantly, and will ensure that it is being used to its maximum potential. Generally, this is the best use of your RAM, even if it doesn't 'look' like it's being used for anything.

I set Google chrome up to have 10 blank tabs and quit it and then ran the test above to measure exactly how much RAM changes before and after launching it. As you can see, launching Chrome took about 76k free memory pages out for the free pool and caused the inactive pool to grow by about 11.5k pages.

Given these numbers, Chrome seems highly unlikely to be causing a leak itself and your web pages might be causing the load. If you can run these tools in terminal, you'll likely see that your system had other issues with memory management and Chrome is likely the straw that puts the final load on the system before it starts swapping. Look for paging activity before you launch Chrome and also have a look at my answer here on why inactive memory is almost never the actual problem and this post hopefully explains how to convince yourself whether you have an actual problem with the memory manager or a specific program.

Isn't Inactive memory a waste of resources?

How can I hide persistent Facetime audio call on macOS?

Solved. Enable Do Not Disturb and the banner will disappear even when on the call.
You can enable Do Not Disturb from the Notification Center. You can access the Notification Center by clicking the Notification Center icon at the top right of the screen. Or by sliding two fingers on the trackpad, from right to left but starting from the outside of the trackpad.


8GB 1333mhz SODIMM in Macbook Pro 13" 2010 (7,1) alongside original 2GB stick

It should work, but it's not recommended.

You should always use the same module, also I believe that way you got some performance benefit. MacRumors has a post about this.

Also, I believe your MacBook Pro won't support more than 8 GB of RAM according to the post, but that I'm not sure. Check out Apple's guide or technical documents for these information.

Another thing to be aware of is if your machine supports 8 GB on a single stick.

This is what I suggests. Buy two matching 4 GB 1066 MHz DDR3 RAM for your MacBook Pro. That way, you won't get into any trouble. It might cost a little more, but it's much more reliable.


Are there any Thunderbolt 2 external DVD drives?

You won't find a Thunderbolt 1 (much less and Thunderbolt 2/3) to an external DVD drive because there simply isn't any need to create one as USB 2.0 has more than enough bandwidth to accommodate even the fastest DVD drives on the market.

To understand why, we have to understand that the fastest DVD you will find is a 24x unit; most will be 16x.  The base write speed is 1x and a 1x speed is 1.32Mb/s so a 24x unit is about 31Mb/s.1

USB 2.0's transfer speed is 280Mb/s or about 35MB/s 2 so even the theoretical fastest DVD drive that you will ever find is less than the max limit of a USB 2.0 connection which, for all intents and purposes, has been obsolete since the beginning of 2009 (USB 3.0).3

There just isn't a need to create a DVD drive with a modern, high speed data transfer interconnect because it's a dying technology and it's fastest transfer rate doesn't even begin to exceed what is already backwards compatible with USB 3.0

1 Wikipedia Modern compact discs support a writing speed of 52X and higher, with some modern DVDs supporting speeds of 16X...

2 Wikipedia  USB 2.0 was released in April 2000, adding a higher maximum signaling rate of 480 Mbit/s (High Speed or High Bandwidth), in addition to the USB 1.x Full Speed signaling rate of 12 Mbit/s. Due to bus access constraints, the effective throughput of the High Speed signaling rate is limited to 280 Mbit/s or 35 MB/s.

3 Wikipedia The USB 3.0 Promoter Group announced on 17 November 2008 that the specification of version 3.0 had been completed...


Can I set an institutional recovery key for Filevault2 after Filevault2 is enabled?

You will need to use fdesetup. If you have created FileVaultMaster.keychain with the institutional key and placed it in /Library/Keychains then fdesetup changerecovery -institutional -keychain will add an institutional key.

I recommend a close reading of the fdesetup man page.

Unlocking iPad Purchased from Government

Governments tend to use MDMs, or Mobile Device Management systems. So the only way to deal with this is to get them to remove the device from their MDM. The only way to do that would be to talk to them.
If, of course, you purchased this iPad legitimately, there would be no issue in doing this. There would be a process in place for removal of a device from MDM.


How do you access the content of the iPhoto bundle from Time Machine?

Open the iPhoto bundle before your enter Time Machine.

When you start Time Machine, the whole folder looks empty (plain white) - which is probably a bug that still needs a fix (I'm on 10.7.3).
You can get to show the contents by toggling the view options.

BTW: It's also possible to use Go to Folder... via ⌘+⇧+G in Time Machine. But this will not help you to enter the iPhoto bundle - whatever the reason is :(


Will an internal optical drive from a non-Apple manufacturer be fully functional in a MBP 13" Mid 2009?

A SATA drive is a SATA drive.  The fact that you were able to put in a SATA optical bay caddy for an SSD is evidence that an aftermarket SATA drive works.

Looking at the SATA connector of the "SuperDrive" you will notice that it's the exact same SATA data and power connector of pretty much any other SATA drive

So, the trick here is finding a SATA optical drive that has the SATA connector in the same location.

There is no reason for a different CD/DVD drive won't work for recovery.  As long as it can read/write, you can use it.  You can boot from CD/DVD by holding down C while booting.  After all, the MacBook Air requires you to use an external (USB) drive if you want to do recovery.

Speaking of recovery, if weight is an issue, why not get a USB flash drive.  You can get a 128GB USB Flash for around $30 and is great for backup/recovery.

Personally speaking I haven't used a genuine Apple Super Drive in years - I either use  external hard drives or USB flash drives.  On the rare occasion I need a CD/DVD drive, I have a Plextor USB CD/DVD RW drive which works perfectly.


upgrade this old MacBook Pro to mountain lion?

The second part is trivial, install Lion or Mountain Lion and let it upgrade everything. That will create a recovery HD where you can then reboot and erase the main volume. If you save the installer after the first download, you can avoid the download the second time.

My experience is that the performance of older computers is as good as or better than the old OS - especially when you are erasing things and migrating files over later (or by hand) as much support for older systems was dropped making Mountain Lion fairly streamlined and responsive.


Macbook pro keeps returning to login window

Are you sure it's the full login screen or is it just asking for your password?

If so, you can turn off "Require Password ______ after sleep or screen saver begins" in the "Security and Privacy" system preference.


I had the same problem. Came across my video effects that I had set in VLC. If mine were enable, the picture was black and white, as in, sharp black and white. I disabled them and the picture was back to normal. Try messing with them to see if that helps.


Might check your system's hosts file.  See http://osxdaily.com/2012/08/07/edit-hosts-file-mac-os-x/ and be sure to create a backup copy of the file before doing any editing.


how to get Finder to automatically open a Finder window / or always keep one open?

You can already open a new window if one is not already open by pressing the

COMMAND-TAB and hold down COMMAND.

Release TAB, keep holding down COMMAND,

then press OPTION and hold it down.

While still holding down OPTION, release COMMAND. Then release OPTION.

As far as doing it automatically you'd probably have to script something.

Is there a way to change the double-press speed on the Apple headphones?

Not possible.I have non-Apple earphones with a mini remote with three buttons - the central one being the one to be double-pressed. I have turned the Internet upside down and haven't found anything close to this, even on jailbreak (my ipod touch is jailbroken).


How do I get out of the "continuous pages" mode?

This is currently not possible. The gap between pages is not customisable and it is not possible to disable continuous scrolling.

You can provide feedback to Apple regarding this at the following page:

Is there a way to change the gesture that invokes Launchpad?

Go to System Preferences > Keyboard > Keyboard Shortcuts > Launchpad & Dock and set a keyboard shortcut to Lauchpad.app.

I want to install Adobe CS 6 on an external hard drive but can't select the install location

Not the answer you want, but whatever.

Re-format your SSD to the default of HFS+ case-insensitive. Almost all Mac software is designed to run on a case-insensitive file system and you using case sensitivity is the problem.

Maybe you'll find a solution here.


How to reset the Master Password without current password on OS X?

The Master Password is more a safety net than a security measure.

Without any user password you may reset or delete the Master Password by booting to your Recovery HD, starting Terminal, mounting your main volume, navigating to /Library/Keychains and deleting the files FileVaultMaster.cer and FileVaultMaster.keychain.

If your main volume is encrypted you won't be able to mount it without a proper FileVault password.


Airport Extreme + USB Drive vs Time Capsule

According to Apple, Airport Extreme with attached disk is not supported for Time Machine. It might work, sometimes, but with a backup system, people usually want more than "might work sometimes".

The easiest way i can think of :

Quit iTunes
Get a Tagger (MusicBrainz Picard, Tagger, Metadatics,...)
Go To your ~/Musik/iTunes/iTunes Media/Music folder
Drop all the "James Blunt" Folders onto the Tagger
Set the Artist to "James Blunt"
Save the Files

After you have done that, reopen iTunes.

Now you have 2 Options :
You can either go through the Tracks by yourself and start listening so iTunes sees, that you changed the Artist.

Or, you can use an AppleScript to refresh your tags.

Your Music should now be cleaned.

And yes, that is in my opinion the easiest, you can go easier, but that requires more scripting which therefore would not be easy.


Keep Mask in Same Spot While Key-Framing Transform - Final Cut Pro

I recently did this (as an experiment) by keyframing the motion of the mask in the opposite direction to the keyframed motion of the transform. In my example someone sitting in a chair (in front of a greenscreen) appeared as if they rose up out of a barrel in some background footage: I keyframed a mask where the bottom edge of the mask started at their head and worked down to their waist; at the same time the keyframes for the transform motion moved the greenscreen footage of their body upwards. The end result was a bit messy, but the bottom edge of the mask stayed roughly level with the lip of the barrel as the superimposed footage moved upwards.
To key frame the changes into my four-cornered mask I started with a narrow mask where all four corners were just above the head and set a first keyframe. I then moved to the end frame and modified the mask so that the bottom two corners were now at waist level, and set the second keyframe. So the mask height grew over the course of the transform.


Why does Powerpoint for Mac not preserve filenames with a slash (/)?

From Microsoft's Known Issues with PowerPoint 2011:

  Some characters cannot be used in file and folder names in PowerPoint
  for Mac 2011

  IMPORTANT   This issue is fixed in Office for Mac 2011 Service Pack 1.
  Click Downloads to download Service Pack 1 or the latest update.

  Characters, including <"> and |, are allowed in file names in
  PowerPoint 2008 and earlier versions, but they must be removed from a
  file name before it can be opened in PowerPoint 2011.

Check your version of PowerPoint for updates to see if this addresses or fixes the issue.

Otherwise, change the filename to include a character that is allowed such as "-". (e.g.: 9-22)


How is my 2nd Airport Extreme Connecting To My 1st Airport Extreme?

SInce your second Airport is connected to the 1st one through an Ethernet cable, and if it isn't out of the normal length for an Ethernet cable I suggest you to choose this link only between your 2 access points (here Airport Extreme).

I advise you to configure the second Airport as follows:

suppress the option "Extend Wireless Network",
configure it in "bridge" mode,
configure it to create a wireless network with the same name and password as the one on your 1st Airport, but with a 2.4 GHz channel chosen so as to be separated from the 1st one channel by 3 empty channels, for example:
1st airport on channel 5, 2nd airport on channel 9 (this is a good practical example I am using to avoid the channels of my neighbours.

For 5 GHz channels just choose 2 differents ones (5 GHz channels don't overlap on each others as 2.4 GHz do).

With such a configuration you avoid to have 2 physical paths between your 2 AP which may cause flapping (packet 1 going path 1, packet 2 going path 2…) and loops (packet 1 going path 1, returned back on path 2…).

Purchase from iTunes Store in Spain when travelling in Spain

You'll have to change the country on your Apple-ID in order to login to the Spain iTunes Store. The process is described here:

https://support.apple.com/bg-bg/HT201389

Remember that you can just continue to purchase from the Australian iTunes Store while visiting Spain. There's nothing preventing you from doing so. So ordinarily there's no reason to switch iTunes stores when travelling in a different country on holiday.

There are drawbacks when changing country on your Apple-ID, such as for example ahving to deal with subscriptions, store credit and/or payment methods requirements of either store.


Application stopped working -- claims it requires new OS X version, but it worked before

According to Updating GitHub Desktop the client updates itself automatically:

  GitHub Desktop automatically downloads updates and installs them when you restart. You can also manually check for updates.

It appears that Github has updated their build toolchain server to a newer version of Xcode not supporting Lion.

You need to stay on the old version.

You may want to contact Github to get the newest build you can still use.

What is the command to copy a file from a directory to another directory in macOS?

You need to protect any whitespace in the names with either "" or \

cp foo 'path/with spaces/to/target'
cp foo path/with\ spaces/to/target

Additionally

Using Tab Completion in bash and other shells will automatically insert \ where necessary
Drag&drop of a file/directory from Finder into a Terminal window will insert the full path of said file/directory, with appropriate escapes
ditto is an alternative to cp which is better at handling metadata, resource forks and other specialities of macOS-specific filesystems.
If you want/need to use environment variables as part of a path (path/to/$TARGET/directory), use "" instead of '' but look out for $ as part of directory/file names


As of MacFuse 4.0.5, you need to

reboot info recovery mode and go to the terminal
disable SIP with csrutil
reboot
install macfuse
link the extension
reboot into recovery mode and re-enable SIP

How do I add new pronunciations to apple dictation?

I don't think that there is anything that is adjustable for Apple's dictation.  I assume that you could use Text Replacements, but I don't think they are interactively called when dictating.
You might have more control if you used a third-party dictation software like Dragon Naturally Speaking.
[Update]
My kids are dyslexic as well. I have used the text to speak to help them with their papers. I tell them to  just their their thoughts out onto paper before going back and fixing any little issues that have come up from the dictation. It's also a way for them to proofread their work to make sure they make sense.


You bought extra cloud storage, not extra phone/pad memory [which is not possible].
The two are utterly unrelated.

You need to transfer some data to a computer, or delete it, to free up extra space on the devices.

MacBook Pro 15" mid 2015 retina randomly freezing, trying to pinpoint the issue (not sleep related)

I know this is an old topic but I have been having the same issue and was finally able to find a solution after trying quite a few different things. For me, turning off Hardware Acceleration within my browser (Chrome) has completely eliminated the freezing. It had ramped up to happening almost every day, but since turning off Hardware Acceleration I haven't had a single crash in 2 weeks.

I hope you have been able to resolve this problem for yourself already, and if not, I hope this trick works for you too!


Command Line (CLI) Command for disconnecting wifi from current network

Use networksetup.
There are several ways to disconnect from a Wi-Fi network via Terminal:

Disable the Wi-Fi service.  This will require root privileges.  The radio will remain on, but it won't connect to anything.
$ sudo networksetup -setnetworkserviceenabled Wi-Fi off

Turn off the airport power (this is like clicking the (GUI) Wi-Fi icon and selecting "turn off Wi-Fi".  You don't need sudo and you should know which interface (en0, en1, etc.) is your Airport adapter.  If you don't try the service and macOS will attempt to guess which one it is.
$ networksetup -setairportpower Wi-Fi off

In the specific case where you don't want auto join, just set the network to not auto join and then toggle the network status using networksetup.
If you just want to disconnect from a WiFi network, disable the adapter:
$ sudo networksetup -setnetworkserviceenabled Wi-Fi off && sleep 15 && sudo networksetup -setnetworkserviceenabled Wi-Fi on
(You can issue the command without sudo but you will get a popup prompting you for a password for each networksetup invocation)


Is it safe to use the 12W iPad 4th gen power adapter for earlier iPads and iPhones?

Yes. The wattage ratings are maximum and all iOS devices will only pull the current they need to charge.

Should a device or an adapter get too hot to operate safely, they will shut off.


How much space does xcode 14.2 really need?

Correct, when it says that you haven't got enough disk space to be install Xcode, you need to free up more space in order to complete the installation.
As far as I remember approx. 40-45 GB of free space is needed to complete the install.

How to Install Ubuntu on Mac with High Sierra and Legacy BIOS Booting Windows 10?

Steps Needed to Install Ubuntu after Installing macOS and Windows 10

Here I assumed the following.

The macOS operating system was installed to a partition formatted Mac OS Extended (Journaled).
Boot Camp was used to install Windows 10.
Windows 10 uses the legacy BIOS boot method.
Windows 10 is version 1803 (i.e. March 2018).
The Desktop Ubuntu version is 18.04.1 LTS.
Ubuntu uses the EFI boot method.
The file ubuntu-18.04.1-desktop-amd64.iso was used to install Ubuntu.

  Note: If you are using APFS or Core Storage, then you will have to make the appropriate minor modifications to these instructions.

Boot to Windows 10.
Download and install gdisk.
Launch the Disk Manager.
Right click on the Windows boot partition and select Shrink volume..., as shown below.

Enter the size needed for Ubuntu. In the example shown below, 100 GB was selected. After entering the amount, select the Shrink button.

The result is shown below. You can exit the Disk Manager. Note: The Disk Manager has updated the Master Boot Record (MBR) partition table, but not the GUID Partition Table (GPT) used by macOS and Ubuntu. This error will be corrected in subsequent steps by using the gdisk command.

Enter the following command in a Administrator Command Prompt window to execute gdisk on your primary internal drive.

gdisk64 \\?\PhysicalDrive0

This will result is output similar to what is shown below.

You can now shutdown Windows 10 and install Ubuntu in the free space.

Adding Partitions for Ubuntu

Below are display snapshots illustrating the partitioning I chose while installing Ubuntu. Basically, I added a new partition for the Ubuntu files and allowed the EFI partition to be default for storing the GRUB boot files. These boot files a stored in a way compatible with the Mac Startup Manager.

When the following display occurs, select Something else, as shown below, then click on the Continue button.

Select free space, as shown below, then click on the + button.

Create swap space. For Use as:, select swap area. For Location for the new partition:, select End of this space. A typical value for swap space is twice the amount of RAM memory installed. Since my Mac has 4 GiB of RAM, the "Size:" field should be 8590 MB. The result is shown below. Next, click on the OK button.

Select free space, as shown below, then click on the + button.

For the Mount point:, select /, as shown below, then click on the OK button.

  Note: The Size: field should automatically default to all the available free space.

The result is shown below.

  Note: Since End of this space was selected in a previous step, the new partitions will not be created in ascending order. This will cause problems with macOS. In a later step, this problem will be corrected.

Next, click on the Install Now button.

Click on the Continue button shown below to allow the installation to proceed passed the partitioning phase.

Correcting Errors in the GPT and MBR Partition Table

When you installed Ubuntu, the MBR partition table was converted from hybrid to protective. This means most of the values in the MBR partition table were erased. This will prevent Windows from booting. Execute the following steps to correct this problem.

If you have not already done so, boot to Ubuntu and login. You should see a desktop similar to what is shown below.

Press the key combination controloptionT to open a Terminal application window. The result should similar to what is shown below.

Enter the following command to execute gdisk on your primary internal drive. You will be prompted for your login password.

sudo gdisk /dev/sda

This will result in output similar to what is shown below.

Is there any mini game available for the today section in notification center yosemite?

Not that I am aware of.

While the Notification Center is intended to replace the Dashboard in OS X, the purpose of the Notification Center is much more narrow and focused than the Dashboard. The Notification Center is for notifications, small utilities and sharing widgets in contrast to the catch-all hodgepodge the Dashboard was home to.


How do you stop a looping Keynote presentation on iPad?


My Ipad 2 does not want to charge: how should i fix it?

Your question is a little vague but we can make a few suggestions based on what it could be.

Replace the charger and cable with a new charger and cable. If the charger went bad (and a cable could masquerade as a bad charger) replacing it (or testing it) with a new one of each should narrow down the problem.
I don't know what "the opposite of charging" means. But if the iPad powers off when you unplug it I would think item one above isn't gonna help as the charger/cable are providing power to the iPad. That might indicate a bad/worn out battery.

Note that the indication that it might be other than the battery (replace the lightning port or logic board) is possible.

Honestly I would take it to a trusted independent service center and see what they say.


How do I show hidden files in Finder with a keyboard shortcut?

⇧⌘. shows hidden files in file dialogs and in some third party applications like TotalFinder. Transmit also has a menu item for toggling hidden files, but it's assigned to ⇧⌘B by default.

There's nothing equivalent to that in Finder though. But you could assign a shortcut to a script like this with FastScripts or by creating an Automator service.

k="com.apple.finder AppleShowAllFiles"
[[ "$(defaults read $k)" == 0 ]] && b=true || b=false
defaults write $k -bool $b
osascript -e 'quit app "Finder"' && open -a Finder


iTunes asks to transfer purchased apps from iPhone even though app sync is off

When you purchase apps (even free) on the device, iTunes always backs this up - and when it Syncs, before it does anything it backs up - and it notices that you have purchased an app/apps - so it wishes to make a backup of these apps. Click transfer and it'll all work fine - happens to me when I buy songs off of the store as well as apps


Using Vimari (Safari extension - link below) one can press f then all links on the page are assigned by letters which you can use to access each. This is very convenient and can save a lot of mouse time.
This extension provides other vim style keybindings that I found really useful (page scrolling, tabs navigation and focusing on input fields)

How do I insert radio buttons in Numbers for iPad?

You can instead radio buttons by double tapping the cell you wish to enter one and then under either the '42' or '=' option you can select true/false. When you check this it will add a radio button or tick box, you can choose which one under the 'i'

I have done this on my iPad so will edit later when I can upload a screen shot.
