What's the 'followupd' in notifications?

This is part of the private CoreFollowup System Framework at

/System/Library/PrivateFrameworks/CoreFollowUp.framework/Versions/A/Support/followupd

There is no documentation about it, but the header files found at (that's for iOS, but I guess the framework is the same):

https://github.com/nst/iOS-Runtime-Headers/tree/master/PrivateFrameworks/CoreFollowUp.framework

don't show any evil things.

I suppose, it's for "following up" on notifications posted by other applications. There is an internal database of which the statements can be grabbed from the binary. It only contains title, body, some IDs and dates. Example:

INSERT INTO notifications (item_id, title, body, unlock_label, relevance_date, activate_action_id, dismiss_action_id, clear_action_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?)

So, no – you should and cannot remove it.

[EDIT]

Regarding the icon. Some examples of system applications having that icon:


Do the Mojave or Catalina patchers support AMD PC GPUs or do you need a flashed card for this?

'older Mac Pro'… specifics would be good.
However, the R9 270X in its HD 7950 guise works fine on a 4,1 with firmware upgrade & a standard 5,1. With an unflashed card you must not use anything which needs the bootscreen - filevault or EFI/firmware lock of any sort.
The smart money was always on keeping the original video card for situations such as these, though neither the GT120 nor the HD5700 can actually run Mojave.
Anecdotally, Mojave is better than High Sierra imho, but personally I wouldn't push any cheesegrater to Catalina.
You'd be wise in any case to very carefully read dosdude's page on Mojave, as it contains a lot of caveats dependent on the precise Mac Pro model.


Alright, I fixed it. I installed a Live image to my flash drive and copied the TestDisk software to it. My live image was Windows 10 To Go, but I believe any OS could handle it.

Then, I ran a scan using TestDisk, and re-enabled the "deleted" partitions. After doing this, I wrote the new GPT to disk, and rebooted. Held the option key, and the partitions showed back up.

I essentially followed this guide, but since my partitions weren't actually in the partition table, it showed them as 'deleted' - setting them back to 'primary' and writing it fixed it.

Moral of the story - Don't mess with any partitions on a Mac from anything else than software in OS X or you may trash your partition table.


even if you think you do not need to know the endianness someone might do. No need to explain why someone does not need it because you may do not know the context. The question is not "do I need to know endianness" but rather "is it big- or little endian". So concentrate on the subject please!

Having said that probably it is the best practice if we do not re-invent the wheel and just rely on the macros Apple provides for this. The reason is because they have spend quite some time to optimize these macros and made sure that works well with the simulator as well as on Mac, iPhone and all of their OS' and hardware.

If you dig down what is happening when you invoke CFSwapInt16BigToHost you may can see comments that suggests these macros are producing probably the best machine code you can get with the help of the compiler optimization:

OS_INLINE
uint16_t
_OSSwapInt16(
    uint16_t        data
)
{
  /* Reduces to 'rev16' with clang */
  return (uint16_t)(data << 8 | data >> 8);
}

OS_INLINE
uint32_t
_OSSwapInt32(
    uint32_t        data
)
{
#if defined(__llvm__)
  data = __builtin_bswap32(data);
#else
  /* This actually generates the best code */
  data = (((data ^ (data >> 16 | (data << 16))) & 0xFF00FFFF) >> 8) ^ (data >> 8 | data << 24);
#endif

  return data;
}


How to stop apps from opening automatically when I plug things in

In iPhoto > Preferences > General select "Connecting Camera opens: no application"

In iTunes select your device and go to Summary and make sure "Automatically sync when this iPhone [or whatever device it is] is connected" is unchecked.

I'm not certain the second one will completely solve opening iTunes since I can't test it as I don't have a cable here with me.


I'm not in front of a Mac at the moment, but is the icon you want available when you customise the toolbar?

To check:

Within Mail go to View > Customize Toolbar (or you can right-click on the Mail toolbar and select Customize Toolbar)
The Customize Toolbar window will appear
Now you can check every button available for the one you're looking for (i.e. the Thumbs down icon - see note below)

NOTE: - The Thumbs up icon will only appear when you've got an email selected that Mail has marked as junk mail. Otherwise it will appear as a Thumbs down icon by default. In other words, what you're really looking for is a Thumbs down icon. Add this to your toolbar and you should be fine.

[EDIT]

Now that I'm in front of a Mac running macOS Sierra, I've determined that the icon you're looking for has been replaced with a new icon (see below):

Once again, this icon will change depending on the current status of the email you have highlighted. If Mail thinks it's already Junk, then the arrow points up instead so that you're removing it out of the trash. Otherwise the arrow points down by default so that clicking on it will trash it.


In Snow Leopard, if I just close it all and start it again it works fine the second time.  Alway fails on the first invocation.  I haven't debugged it further.


What are the physical anti-theft protection for MacBook Pro (2015 Retina)

You get a case with a lock.

The Ledge Case MacBook Pro Touch Bar Lock is a nice one that a relative showed me the other day, because he, like you tend to have their MacBook Pro out in the open in coffee shops and will leave it unattended.

Disclaimer:  I have never used nor owned one of these because I simply won't leave any computer/device unattended.  I had my personal laptop stolen from work (at the University Library) when I put down my laptop bag to punch in (still used cards back then).  In the time it took for me to walk the 20 feet (3m) from my desk to the time clock, it was gone.  Since then, my device is either on me, or physically locked away.


Xcode 4.6.1 install hangs at "Installing - less than one minute" on Lion

The problem in this case appears to be that the developer site was down.  Once it came up, install proceeded without problem.


Lion - Macbook randomly wakes up from sleep when lid is closed

It is possible to determine what caused the system to wake

Open Console (/Applications/Utilities/Console)
Set the search filter to 'wake'

You're looking for the latest entry that has something like this:

Wake reason = EC LID0

(In the example above, opening the display clamshell caused the machine to be woken)

Here's a list of wake 'reasons' from OSXDaily

This should shed some light on what is waking the machine, then you can go from there.


What is the best way to limit the time of use of iPad 4?

Sorry but iPads (and iPhones) aren't intended to be used as multi-user devices. At least not like you mean with different profiles like you would find in Windows devices or recent version of Android.

The closest thing on iOS devices is Guided Access, where you can lock the device to a particular application and specify time limits. You need to enable it in "Settings > General > Accessibility > Guided Access" choosing a password and turning on the Accessibility shortcut which allows you to bring up the Guided Access feature by triple clicking the Home button. Then you open the app you want to lock the device to, triple-click the Home button and it will allow you to specify time limits, and allow you to enable or disable certain parts of the device. Then click Start.

You can read more about Guided Access on Apple's website here.

There are other third party applications that promise to offer similar features, you might want to investigate them. Of the ones I looked at none stood out and the reviews didn't inspire confidence.


How to create an up to date ML recovery?

Yes,

Download Mountain Lion again from the App Store and create a bootable USB from the new downloaded files.

Either by using Disk Utility or by using Lion Disk Maker.

  Full tutorial can be found on Arstechnica website


outlook.com (Exchange ActiveSync) on OS X Mountain Lion

Unlike iOS, the Mail app in OS X does not currently support Exchange ActiveSync.

Exchange ActiveSync is different from the standard Exchange format. A mail client that supports Exchange may not support EAS.


Should diskutil list an unmounted drive?

From the manual page diskutil for the list verb:

  List disks, including internal and external disks, whole disks and partitions, and various kinds of virtual or offline disks.

So, yes it should list all disks, even if not mounted.

Note however, if you've ejected the disk instead of un-mounting it, it will not appear when using diskutil list. Also, once a disk have been un-mounted, it will not cause a flag to be raise as if pulling out a USB flash drive while still mounted, when disconnecting the un-mounted disk.


Apple Maps Won't Navigate (Sporadic Problem)

This happens whenever the "From" location is a fixed address, rather than "Current location". Even if that address is your current location when you start, Maps will be in a different mode, as you have discovered.

To switch from the static navigation mode to turn-by-turn mode:

Tap End.
Choose those directions again.
Don't tap Go yet. Tap the blue text after "From".
Replace the text there with "Current location" and tap Route.
Now tap Go.

Routes with a fixed start address would probably be from Apple Maps on your Mac, which doesn't offer turn-by-turn directions. If you want to remove these from your history on your iPhone, swipe left on those items in the list.


Does the 27-inch iMac (MC511LL/A) have a true thunderbolt port or just a mini-display port?

There's an FAQ on the Apple Support page: http://support.apple.com/kb/HT5219?viewlocale=en_US&locale=en_US#4 Since your Mac is Mid 2010, it does not have a thunderbolt port.

Mobile Account home directory trees are stored locally (normally under /Users) but are synced with a home directory tree on the server.

Other than local files for the user home (which is good if you are using programs that depend on local disk for performance or other reasons), I can't remember any special properties other than the fact that you have two copies of the user's files (which doesn't really count as a backup). Both types of accounts can be managed.


Are you sure your SMS/Text Messages are gone? Assuming you have iOS configured to keep them, they should be there.

If you're not sure, here is how to check:

Tap on your iPhone Settings
Swipe up until you see the Messages option
Tap on Messages
Swipe up until you see the Keep Messages option. This should show either 30 Days, 1 Year, or Forever.

If it shows Forever you should be okay. Likewise, if it shows 1 Year you may be okay depending on how far back you need to go. However, if it's only set at 30 Days then you're going to be out of luck unless you have backups for the period you need (which you may do if you have a good backup regime in place).

In terms of accessing past messages, may people don't realise they can do this quite easily by using the following procedure:

Open Messages
Tap on your spouse's name
When the messages appear, tap at the top centre of the screen to load more messages.

NOTE: It's easiest to tap where the Time is displayed. Each time you do this more messages will load. Depending on how far back you want to go, you may need to tap many times to load them all.


How do I turn up the brightness on my MacBook without being able to see the screen or use shortcuts?

I ended up using a flashlight to see enough of the screen to turn the slider up. After thinking about it I realized I could have plugged in an external monitor as well.


How do I find what my DPI setting is in OS X?

You can easily calculate DPI on sites like this: https://www.sven.de/dpi/


What does photolibraryd do whenever I log in to my Mac?

It also matches photos that are on your local library and in iCloud. So for instance, if you have a sync problem, you can toggle iCloud Photo Library in Photos app → Preferences → iCloud and this will cause a complete re-sync of the local and the iCloud photos.

When this happens (at least on my 51K photo library), it takes 24 hours or so of photolibraryd running to match photos and sync the changes.


I assume that by "I shared", you mean that you've granted other users permissions to read and/or modify this file. But that's all this action does: Granting permissions. It's only half the way, and usually the second in order.

The simplest way (and the only one I know of) for the files to actually be shared between different users, is to have them in your "Shared" folder, which can be found in the "users" folder.

You would then access those file from this directory. For your own convenience, you can add this directory to your (left) Finder sidebar for quicker access.

There's a relatively recent and quite comprehensive article on sharing folders between users with this method over at MacObserver.


How do you mount -bind a local directory?

As mentioned by another user on StackOverflow, you can use an NFS mount do to this. However, it requires a little bit of one-time setup.

First, you'll need to set up an /etc/exports file (if you haven't done so already).

$ sudo tee -a /etc/exports <<< "/ -alldirs -mapall=$USER localhost"

Secondly, you'll need to start the rpc and nfsd services.

$ sudo launchctl start com.apple.rpcbind
$ sudo nfsd start

From there, give NFSd a little bit to wake up and get breakfast, and you should be good to mount:

$ sudo mount localhost:/path/to/target ./mnt

To restore the original contents, just do

$ sudo umount ./mnt


iPhone 5 sound not playing through headphones

If the problem persists, you may have a whole different problem on your hands. Basically, dust can get into the earpod jack and cause an electrical disruption. To fix this, put the earpod plug in the jack until you hear the click, and then pull it out again. Do this over and over again.
   Try it out, and if you have sound, then you have fixed it. If this has not happened yet, it will most likely happen in the near future, so be prepared. (it happens to some apple devices after a while).


App Store opens unDock Lite product page seemingly randomly

Is there any mention of the app or the page in ~/Library/Cookies/com.apple.appstore.plist? At least one other AskDifferent user had trouble with this file and solved the problem by deleting it - maybe that should be the last resort though.

You can also enable "debug mode" in the Mac App Store by doing defaults write com.apple.appstore ShowDebugMenu -boolean YES - when you have done that you will see a new menu:

I would try Clear Cookies first, and if that doesn't help, Reset Application.


Cannot update built-in apps on a brand new macbook

Sometimes when you log in with new device the App Store gets bit confused.

Go to you Account in App Store and verify it showing the right device.


Is there an extension to give Safari the same multiple search engine functionality as Chrome?

Try SafariKeywordSearch. It allows you to set up custom searches triggered by keywords preceding searches. For example, I have it set so that goto Ask Different uses Google's "I'm Feeling Lucky" to send me to the first Google result for "Ask Different".

There's a good set of built-in defaults, and it's pretty easy to add almost any site-specific search out there, by making a small edit to the URL. There are instructions on the site.


How do I find the log for the shutdown process?

Instead of looking at logs, I would start by booting in verbose mode. (It will also shut down in verbose mode.) Just hold Command ⌘ + V at boot.


Thunderbolt Cinema Display to nonThunderbolt Macbook Pro 2010

Ultimately, the Thunderbolt Display will not work with a 2010 or earlier mac.

While Thunderbolt output ports are backwards compatible with Mini DisplayPort, the reverse is not true. So, if you had a 2011 or newer mac with a thunderbolt port, you could plug in an older Mini DisplayPort monitor, and it will work perfectly, but you cannot plug a newer thunderbolt monitor into an older Mini DisplayPort port.

Furthermore, the monitor cannot be connected through USB or FireWire, as they do not carry a display signal.

All that to say, I'm afraid the screen you were given at work is not going to function with your 2010 MacBook Pro.


Can't send outgoing messages in Mac Mail

As stated before, all this means is your outgoing server credentials are incorrect in the Mail App.

In order to check the outgoing server's credentials go to  Mail menu > Preferences > Accounts > find your Gmail account. Click on your gmail account then under "outgoing server" check what server is chosen by default then click "edit smtp server list" at bottom.

Once there double check all the server info. Make sure it has your email spelled correct and password correct, make sure authentication is set to "password" then make sure you use SSL and use port 465 or 587.


Pros & Cons of still running Mac OS X Snow Leopard?

Pros:

1) Speed. 10.6.x runs faster on older hardware, particularly if you only have a regular hard drive. I see the beachball much more often in Mountain Lion than I did in Snow Leopard because my MBPro only has a 5400-RPM drive and ML seems to access the hard disk a lot more. SSD is preferred for Lion and Mountain Lion.

2) Colored icons in the Finder sidebar. Apple made them grayscale in 10.7 and 10.8, a huge step back for usability. There is a hack that will re-enable color, but it can cause Finder instability.

3) Rosetta. If you upgrade to 10.7/10.8, you'll lose the ability to run apps based on PPC code.

Cons:

1) No iCloud. There are workarounds but I've never been able to get them to work properly or reliably.

2) Security updates. However, you can "stay safe" just by keeping Flash up-to-date (or uninstall it and only use Chrome for Flash), disabling Java in your web browsers, avoiding pirated software, running Little Snitch, and periodically running AV software.

These are the ones that stand out to me. I'm sure others can add to this list.


Grant "Full Disk Access" to Workflows run via the Services menu

The problem is that the automator service inherits the permissions of the application it's running from.

Automator has Full Disk Access. So, if you run it from Automator, it works!

But let's say you're running Chess.app, and from the top menu, you select Chess → Services → My Automator Workflow. Chess.app does not have full disk access, so the workflow fails. I expect that if you grant Chess.app Full Disk Access in System Preferences, the Workflow will work when run from Chess.app—but not when run from DVD Player.app.

Yes, I recognize that this is incredibly frustrating.


How can I remove unchecked and deleted songs in iTunes from my iPhone?

In iTunes, you can select the music to sync by track, playlist, artist, album, genre.

In order to delete a track from the iPhone, it shouldn't match any of the aforementioned criteria. Maybe the tracks are included in some smart playlist which is synced (Recent?).


How to benchmark a NAS from a Mac (Neither fio nor bonnie++ work)

Bonnie++ can be installed this way:
Download Bonnie++ 1.98 from here:
https://www.coker.com.au/bonnie++/bonnie++-1.98.tgz
Extract the source code:
tar -xvzf bonnie++-1.98.tgz

Apply it to the source code using the patch utility:
cd bonnie++-1.98
patch < ../remove-large-file-support-macros.diff

Now configure and compile like usual:
./configure
make
make install


How many photos will fit on a 16 GB  iPad?

Short answer: 16GB should be fine for photos.

Long Answer: Your question is hard to answer with any accuracy as photos come in a variety of sizes depending on resolution, subject matter etc. For example, a photo taken on your 3GS iphone will be smaller than one taken on your 4GS iphone, which will also be smaller than one taken on your nikon DSLR digital camera. And as you could also reduce the image size based on how you want the photos to appear on your ipad, it becomes a bit more complicated to answer.

However, some math might give you a better idea at least.

1GB = 1024 MB so 16GB is 16384MB. Assuming you lose say 4GB for the in built apps and skype etc. we could say you might be left with 12GB or 12288MB.

Let's assume your mother isn't a professional photographer with a 30 megapixel dslr camera, but for the sake of being conservative we'll say all of her photos are taken on a hi definition camera, like the iPhone 4s. Depending on a variety of factors the photo size will range from about 1.5mb to 3mb at full size (bearing in mind these are still HUGE photos at full res.) If we say 2.25 is an average photo size, you're still left with roughly 5,500 photos on your spare 12GB of space.

Bearing in mind this is still pretty conservative the answer is that your mum can store literally thousands of photos in her 16GB iPad. If you weren't using a really hi def camera like the 4s iPhone, your photo sizes could be as small as 100 or 200 kb's each and the number is more like 50,000 photos.

Hope that's helped.


Can the Cellular Applewatch operate without an iPhone?

My suggestion: Buy a cheap refurbished iPhone, bond the watch to it, then put the phone in a drawer. The LTE Apple Watch doesn’t need the iPhone to be on or nearby if it’s a Series 4 or later. It is NOT possible to set up an Apple Watch on a number that s completely separate from its iPhone bond mate.

BTW, she can make calls from the Apple Watch without the iPhone involved, but it has to be bonded to an iPhone.

I’m betting you know somebody who has an iPhone 6/7 with a shattered screen or bad battery.


Issues with installing Social Engineering Toolkit (S.E.T)

In a vanilla Lion installing Social Engineering Toolkit works if you use

git clone https://github.com/trustedsec/social-engineer-toolkit
cd social-engineer-toolkit
sudo python setup.py install

(which will install some necessary tools/libraries to /Library/Python/2.7/site-packages).

After "installing" the toolkit use sudo ./setoolkit to start the SE Toolkit.

Here are some env variables:

$ python --version
Python 2.7.1
$ which python
/usr/bin/python
$ python -c "import sys;print(sys.path)"
['', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC', '/Library/Python/2.7/site-packages']
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

You probably installed Python 3.5 – which is not included in OS X Lion – and modified some env variables. Without further informations your SE Toolkit install can't be salvaged.


I found a possible workaround myself. Firstly cut off internet connection of your computer, then open iTunes, hit Podcasts tab, then iTunes will hang for a while but not complete freeze, delete suspected podcasts that may cause freeze, lastly reestablish internet connection.


Can I use the promotional Apple images in my apps tutorial screen?

If it's purely for instructional purposes, then you should be all set to go ahead and use the images. However, I don't work for Apple, so I don't know the exact details regarding their image use policy.


Email alerts (dock icon and app sidebar) arent showing up in any more in 10.9

Mail.app in 10.9 has had (and still have, for some) massive problems with Gmail-based accounts.

In the first couple of Developer Previews Mail.app was completely unusable for me. When the Golden Master (final release) of 10.9 came out it was better but still horrible compared to earlier versions of OS X. In my case, Mail did actually show the unread badge, it just showed a number was way off!

Try to update OS X to 10.9.1 which makes Gmail-based accounts work better. Also, there was a stand-alone Mail Update for Mavericks which fixed the badge problem for my.

You probably know but it's through the App Store or Apple menu () > Software Update.


Can't see family sharing invitation on iPad mini

Confirm that your device is running the version of iOS that you think that it is under Settings > General

It might help to associate devices with that Apple ID, or at least log in to iTunes with the Apple ID to make sure that everything about the Apple ID works
http://support.apple.com/en-us/HT204074

You can also get to the invitation from Settings > iCloud > Family Sharing

here is info from the start

I was able to resolve all of my issues.


How do i correct an incorrect email address?

First check if the incorrect address is in Contacts. If so, you can just edit and correct it there.

If not, then it is probably stored in the address history. You can open this from the Window->Previous Recipients menu. You can search for the address in the dialog and delete it. (You might need to do this, even if you edit the email address in Contacts, as the wrong address might have been stored in the history.)


Tell if running process is running under Rosetta or is M1-native by Command Line

You can definitely rule out some things (go to the terminal).
e.g.
# ps -ef | grep -i firefox$
  502 56288     1   0 11Mar21 ??       207:43.89 /Applications/Firefox.app/Contents/MacOS/firefox

USE the executable name and pass to file command.
# file /Applications/Firefox.app/Contents/MacOS/firefox
/Applications/Firefox.app/Contents/MacOS/firefox: Mach-O 64-bit executable x86_64

So if that gives you x86_64 it has to be running under Rosetta - it's got only x86_64 architecture (the pre-M1 one).
On a M1 machine some things ship with universal binaries - for instance do the same thing for Safari and I get something like this (sorry machine is air-gapped .. this is TCP-over-ME so may not be 100% correct :-)
# file /Applications/Safari.app/Contents/MacOS/Safari
/Applications/Safari.app/Contents/MacOS/Safari:Mach-O universal binary with 2 architectures: [x86_64:Mach_o 64 bit executable x86_64][arm64e:Mach-o 64-bit executable arm64e]

.. and then proceeds to give output that is for each architecture ... According to Apple it will "prefer" arm64e.


Two versions of the same app in Launchpad

Yes is possible to have two or more versions from the same application.

In order to work, you should rename your apps on Applications folder:

 /Applications/Processing-1.5
 /Applications/Processing-2.0

The main issue with this, is that usually both apps will share configuration files, and sometimes will be a problem.


Where can I download iPad apps in macOS Catalina Beta?

It's up to the developer to release apps, so in the case of Apple, you have some of these apps already on Mojave. News, Home, etc...

https://developer.apple.com/ipad-apps-for-mac/

  Now it’s incredibly simple to start building a native Mac app from your current iPad app. Your apps share the same project and source code, so you can efficiently convert your iPad app’s desktop-class features, and add more just for Mac.

What's left unsaid, is the developer needs to finish a Mac version of the app and then ship that app in a way of their choosing (through the Mac App Store, through direct download / side load) so the developers would release the app to you or to the world when and how they choose and you wouldn't somehow run an iPad version of the app on MacOS Catalina.

More Apple apps are listed as coming from iOS/iPadOS on Catalina and I would expect developers to start releasing these (perhaps through the TestFlight framework) and publicly once each Mac version of an iOS/iPadOS app is ready for you to run.

So far, I've seen no real apps yet since it's so soon in the testing cycle, but as we get closer to fall, I would be surprised if you don't have some companies extending tests to Catalina pre-release over time for a public beta of their work before the official release date.


new SSD - APFS not in list of options for format

Disk Utility looks like it's pre-Yosemite [skeuomorphic dots top left] which will have no idea what APFS is.
Try booting to Internet Recovery using  Cmd ⌘   Opt ⌥     R   & you should get the chance to install the latest OS the machine can run, rather than the one it came with.

You should also get a Disk Utility that understands APFS.


Applescript: Ask user for list of numbers and open new tabs with those numbers as URLs

If you're copying and pasting a list, as in what's shown in your question, as in lines of text that have the (hidden) newline character at the end of each line, you can use the following:

display dialog "Please Enter IDs" with icon caution default answer ""
set id_list to text returned of result

if id_list is not "" then
    set i to 1
    repeat (count paragraphs in id_list) times
        tell application "Google Chrome"
            make new tab at end of tabs of window 1 with properties {URL:(paragraph i of id_list)}
        end tell
        set i to i + 1
    end repeat
end if

Here's the Event Log in AppleScript Editor after running the AppleScript code above:

Does TimeMachine has an higher priority than the sleep delay?

There is a sleep assertion for Time Machine. So while doing a backup your mac won't enter sleep mode. If you are not sure, while a backup is in progress, check with this command: pmset -g assertions. In the processes that prevent sleep mode you will found: BackgroundTask named: "Time Machine backup"

Mac Pro booting to Kali Linux screen without HDD installed

Considering that you are only seeing a gray screen with no logo or symbol at all, I'd try some of these starts options, as well as macOS Recovery to repair your Macintosh HD volume if needed.

There are a few things you could do at startup.
First, you could hold Option on the keyboard immediately after powering on your Mac, and you should be presented with a screen with a list of volumes to boot you Mac from. Choose Macintosh HD from the list. Have a look at: How to set up and use an external Mac startup disk

Next, you could hold the X key immediately after powering on your Mac in order to force the machine to attempt to boot from the internal macOS volume.

Lastly, you could hold CommandR in order to access macOS Recovery. This would allow you to check your Mac's disk configuration and even repair the macOS volume if needed. In recovery mode, you can also change your startup disk:

  To quit macOS Recovery, choose Restart or Shut Down from the Apple () menu. If you want to choose a different startup disk before quitting, choose Startup Disk from the Apple menu.

Have a look at: About macOS Recovery

You can find more startup options here: Startup key combinations for Mac

UPDATE: I was able to find an answer that seems to address rEFInd allowing your Mac to boot into neither Recovery nor macOS: Kali Linux auto boot
I understand that you did remove rEFInd, but this may be worth looking into.


On my machine, (10.9.2) changing the log level for the sftp server in sshd just makes everything spit out onto /var/system.log/ along with the rest of sshd's log output.

e.g. part of my system.log filtered for 'sftp' after a single connect

I have the same Air as you and I am getting 5-6 hours. So not to much off of what the advertised amount is. Your battery sounds faulty to me.

The last computer I had had a faulty battery. It was replaced for free and within a couple of days. Back then they simply replaced the battery on the MB because it was removable. Chances are now they will give you a new laptop because the battery on the Air is harder to remove. You might be without a computer for a few days though. I don't know what they do in other countries, but in Spain they just took it and mailed it to Holland to get fixed and then mailed it back.


Will updating my iPad to iOS 5 cause me to lose media? (the answer is YES)

iDevices are designed to be linked to an iTunes library where they get their content. If you've never trusted iTunes before and been manually copying items onto your iDevice then you're just making it hard on yourself.

Synchronizing your files and upgrading the iOS are separate steps. I would recommend you get the iPad linked to your iTunes library properly and synchronization figured out before trying to upgrade lest you lose your iPad content in the process.

First, make sure your iTunes and your iPad are registered to the same AppleID you used to download your apps and other iTunes store items. (This may already be the case if it's telling you about purchases, but check.)

Next, download your past purchases to your Mac.

For other items like your own music and video files, the synchronization is one-way. If they're not in your iTunes then they won't sync back from your iPad.

Try using manual mode for those items if you're happy leaving well enough alone with keeping those items on your iPad.

Otherwise, you'll have get these from your original source (ideally) or use a third-party utility to extract the files from the device. It's been a while since I've had to do that myself, but as I recall it was a bit messy since the files lost their original filenames when they were stored in the device's filesystem/database. At least I think you can get them out somehow, but yes, it might be buggy.

The key is to have everything in iTunes before allowing the iOS upgrade to remove anything from the iPad. In my own experience, everything was right back where it was after the iOS upgrade, even though I had some similar warnings, but if you don't already have the items in iTunes then it might be a different story.


Prevent Wake-on-LAN when other devices wake from sleep or get connected to power

Under Device Backups, in iTunes 12.4.1 Preferences, there is a checkbox "Prevent iPods,iPhone & iPads from syncing automatically". That should help.


Someone else asked this here: https://discussions.apple.com/thread/6754677?start=0&tstart=0

The answer given was "It seem [sic] Preview in OS X has a capability of making a normal PDF (non-editable) editable and I'm guessing that it's doubling up on top of the editable symbol that's already in your editable PDF. I had the same problem and I was making my PDF editable with Adobe Acrobat Pro. I fixed the issue by changing the appearance setting in properties for the checkbox."


Is there a way to stop downloading an app without restarting the iPhone?

You can pause the download while it's in the "loading" stage by tapping the app icon (tap again to resume), but I couldn't find a way to actually cancel the download.


How can Apple Mail be configured to mimic Gmail's "Archiving" behaviour for a generic IMAP account?

Mail does have an action called "Archive" in the Message menu that moves the current message in to  a directory called "Archive."  I use it all day every day on my work IMAP account just like in Gmail.  I stash everything in there and just rely on search to find what I need.  It works great.

I don't think there's a way to remap the Delete key to perform an Archive action instead, but Archive does have a keyboard shortcut: control-command-A.  If you find that as clunky as I do, you can remap it in System Preferences' Keyboard pane.

You can also add Archive to your toolbar if that's more your thing.


Can you have a FaceTime session while also using another VOIP solution like BlueJeans or Skype

No.

While it is possible to have 2 simultaneous active VoIP calls (using different solutions) on your iOS device, it is not possible to be heard at the same time on both of them. As soon as you make the second call, the first one is put on hold.

You can switch between the two, but you can be conversing only over one call at a time.


"Moving" MP3s from one mac book to the next?

By default, iTunes/Music copies audio files to /Music/iTunes. If you've got 15 GB of music in two locations, then you've probably got them duplicated already.
When you get a new Mac, you can use Migration Assistant to copy all your files and settings, and the process will be handled automatically for you.
If you don't want to use Migration Assistant, you can just copy the 'iTunes' folder inside /Music. The new app will update its Library database will all your data.


How to keep images in Mail for offline reading?

How do I upgrade a mac mini from OSX 10.4.11 to 10.6.8

I believe your mac mini supports 10.6 snow leopard. So all you have to do is buy the snow leopard install disc like from amazon (http://www.amazon.com/Mac-version-10-6-3-Snow-Leopard/dp/B001AMHWP8/ref=sr_1_1?ie=UTF8&qid=1358911973&sr=8-1&keywords=snowleopard), then plug the disc in and do the upgrade.


Connecting Mac Book Pro 2017 to 2 Projectors via USB C

According to Apple's Technical Specifications  13” 2017 MacBook Pro is able to support 2 external displays.

Simultaneously supports full native resolution on the built-in display at millions of colors and:

One display with 5120x2880 resolution at 60Hz at over a billion colours
Up to two displays with 4096x2304 resolution at 60Hz at millions of colours
Up to two displays with 3840x2160 resolution at 60Hz at over a billion colours

So, three total screens is a yes, four or more is a no. What’s undetermined is if you can run closed clamshell and have three distinct and active external displays and nothing on the internal display.


Using single Apple ID with multiple Apple Developer Program memberships

A single Apple ID can be a part of more than one, different development teams.

You are enrolled in the Enterprise account as a Developer. You can easily use your Apple ID to enroll into Apple Developer Program as an individual.

Once your membership request is approved, you'll be the Agent in your personal team and Developer in the company's Enterprise team. When using your Apple ID to log into Apple Developer website or into Xcode, you'll be given the option to select the team of your choosing.


Will the Lightning to USB 3 adapter let me connect via Xcode for debugging via the power passthrough?

No, it is not possible. It can only be used to supply power to the iPad/iPhone.

The only way to connect multiple things is to use a traditional powered USB-hub connected to the single USB-port available on the Lightning to USB 3 Camera Adapter.


MacPro Early 2008, how to hook up yellow power cords to the graphics card?

The two power cables are interchangeable. Order is unimportant.

They were originally envisaged as one per card, in 2 PCI slots, but they're duplicates of one another.

From the Service Source Manual


Cannot boot normally or in safe mode, booting to recovery mode results in circle with line through it

The graphical anomalies that you're seeing on boot are usually indicative of a GPU failure or logic board failure; for a MacBook Pro the difference between the two is immaterial in terms of what would need to be replaced since the GPU is soldered to the logic board. Booting into safe mode disables the GPU which likely explains your ability to get somewhere without having the machine kernel panic and power off.
The video you posted shows the machine running fsck_hfs, which checks the filesystem for errors, and it lists some issues with the filesystem. There's a possibility that you're dealing with GPU/board failure compounded with filesystem corruption caused by/during the failure of the hardware.
The diagnostics that would be available at an Apple Store (or over the phone as long as your machine is new enough) would be able to determine with a high degree of certainty whether or not you have a hardware issue.


Can I uninstall stock Apple applications (e.g. Stickies)

Yes, technically, you can, but you shouldn't.

Reasons you shouldn't:

Apple will sometimes update the applications in minor OS upgrades. As the rest of the application isn't there, you end up with only the files that were changed.
What if you decide you need them in the future? You'll have to reinstall the OS.
On Snow Leopard and later, the apps you mention take up almost no space - Mail is a measly 77 megs.

If you do decide to delete them, it's easy: drag them to the Trash or hit Command-delete just like any other file. Do make a backup before you delete things, and do also test the apps you delete or trim right away. You want the Mac to crash now while you remember what you deleted.

Be hesitant to delete Image Capture or TextEdit. The former controls scanning and importing pictures from any device and the latter is called for in some cases if you need to edit a system file. I'd also say leave Mail around - especially if you ever will set up a guest account and let someone use your Mac for a short amount of time.

You probably won't hose up too much with the rest. I should mention again that this is very much discouraged because it breaks the system that tracks what software was installed. Software installed by Apple gets recorded in a receipts database, and these receipts don't contemplate a partial uninstallation and you are gambling that there isn't a connection between these apps and others you may need later.

Why not look elsewhere to save some space? You can and should look in /Library/Application Support and delete some of the iDVD loops and Audio Loops for GarageBand. Also, compare the size of all the apps you intend to clean out and compare it to one music video or a few songs in iTunes. You probably can find much better targets to free up substantial space rather than getting rid of some essential system utilities that take up little to no space in reality.


How to manually add ssh key to keychain?

Try adding a new item in the keychain app by pressing the small + Button at the bottom. It should look like this.


Make a global shortcut for a particular app

It sounds like you want to switch to the OBS Studio App so you can switch scenes, etc.
You can use Automator to create a custom service to launch the application of choice and bind a global keyboard shortcut to do so.

Open Automator, select New Document and Choose Quick Action (Service)
In Workflow Receives (Service Receives) drop-down list select No Input
Drag Launch Application from the Actions list to the right side
Select the OBS App as the Launch Application
Save the Automator Quick Action (Service) as "Launch OBS"
In System Preferences -> Keyboard -> Shortcuts -> Services scroll down and find Launch OBS and set a keyboard shortcut for it.

This will open OBS and bring up the minimized window and it will unhide it as well.

There's a great deal of potential solutions that may be even more useful in controlling OBS. If you rethink your workflow a bit, the deeper problem is controlling OBS while you are streaming or recording.
OBS has a websocket API and can be remotely controlled via a web browser but it can also be remotely controlled via iOS/iPad Apps as well as actual hardware controller boxes (stream deck or MIDI controller) with a myriad of programable buttons and dials to control OBS and a lot more.  You can add an inexpensive second monitor, even an old iPad setup as a second monitor and put OBS on the iPad.


Thank you for your input

So finally I managed to do it (at least I think so)

I embedded an Applescript to change the background in a shell script which I added it to launchd.

This is what it looks like:

Script "scriptly.sh"

#!/bin/bash
osascript -e '
set myhour to get the (hours of (current date))
set myminutes to get the (minutes of (current date))
set mypicturenumber to (myhour - 12) * 12 + myminutes / 5 as integer
if mypicturenumber < 0 then
    set mypicturenumber to (288 + mypicturenumber)
end if
set picnumber to 0
if mypicturenumber > 99 then
    set picnumber to "0" & mypicturenumber
end if

if (99 ≥ mypicturenumber) = (9 < mypicturenumber) then
    set picnumber to "00" & mypicturenumber
end if
if 9 ≥ mypicturenumber then
    set picnumber to "000" & mypicturenumber
end if
tell application "Finder"
    set desktop picture to {"Macintosh HD:users:USERNAME:Individualfile:backgrounds:earth:earth24h" & picnumber & ".png"} as alias
end tell
'

launchd file "com.individual.Background.plist"

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

    <key>StartInterval</key>
    <integer>300</integer>
    <key>UserName</key>
    <string>USERNAME</string>
</dict>
</plist>

command to put it in action

launchctl load /Users/USERNAME/Individualfile/com.individual.Background.plist

EDIT:

The last command is there to load the script directly, however It will not be executed on startup. To do That you have to copy the file

com.individual.Background.plist

to the ~/Libary/LaunchAgents/ folder.


What is the chance that jailbreaking my iPhone will brick the phone?

Jailbreaking utilizes an exploit in the OS (or in the latest cast, the boot ROM), and injects the payload onto the phone, which is usually a loader to install Cydia, or Cydia itself.  Cydia is the source for applications not in the App Store, and once this is loaded, other software can be installed which could modify system files.  One such case is Winterboard, which allows you to customize aspects of the UI.

With regards to question 1:

It depends on what happens during the jailbreak.  If, for example, you're running the exploit to jailbreak the phone and the battery dies (or the software malfunctions), there's a chance you'll brick it.  It's hard to pin a percentage on it.

With regards to question 2:

Since Apple is expecting their software to be running on the phone, it may do some things that could brick the phone.  Again, it definitely varies on what has been changed, how the jailbreak was performed, etc.  Personally if Apple comes out with an iOS update, I'm not going to just allow it to run.  If I want it, first thing I'd do is restore the original firmware via iTunes.

How do I eliminate duplicate files and folders in iCloud?

If you have a Macintosh, you could download a duplicate file finder such as Gemini, Photos duplicate cleaner, dr. cleaner, all available on the app store. Enable the icloud folder on your mac in Finder via Preferences (file > preferences, or cmd-,) while focusing finder to enable the iCloud folder to show on your list of shortcuts.

You need to be logged into iCloud on your Mac to enable this, as well as have it checked to on in the icloud preference plane.

If your only device is an iPhone, perhaps there are the same type of apps in the app store. You can enable the iCloud shortcut to view your files just like on the Mac as well. But other than these options, you may need to do it manually.

Are there Fingerprint Readers that Can Connect to my Macbook?

I assume your laptop does not come with Touch ID.  The only 3rd party unit I know of is the Eikon To Go USB Fingerprint Reader. Made to work on Macs.  You can find it here, and here. This unit is described on many other web sites. Just Google it to see other sites. I think this unit is out of production but Amazon advertises the reader.  I'd check to make sure its compatible with your system software.

Do you own a regular scanner? Since you only need a print of your fingerprint, have you thought of scanning your finger by holding it down on scanner screen and scanning it?


MacBook Retina 12" dont have Ethernet port built-in hence en0 is your wifi. Do you use any kind of adapter for ethernet to work?

370GB unused but cannot shrink APFS container

Unfortunately, due to the way Boot Camp (especially its partitions) works in conjunction with APFS, you cannot arbitrarily resize either the Boot Camp partition nor the APFS Container once both are present on the same device; the only viable method for reallocating capacities is destructive to the Boot camp partition.

Back up your Boot Camp Partition (use eg. WinClone or the Windows Backup tool) then use Boot Camp Assistant to remove the Boot Camp partition, reboot, then start over by using Boot Camp Assistant to create the new Boot Camp partition in the size required.


What happened to Shared Links in Safari 11.0

You can find a plist of your feeds at ~/Library/Safari/WebFeedSources.plist. Use this command to get a list in a human-readable format:

plutil -p ~/Library/Safari/WebFeedSources.plist

It is annoying that the Shared Links feature was removed in Safari 11 -- Apple seems to add/remove RSS support every few years...


macOS: Disable popup showing accented characters when holding down a key

In macOS, when a key is held down while entering text, a popup is shown which lets one choose between various accented forms of the character. To disable this execute the following command-line in the Terminal.app:

defaults write -g ApplePressAndHoldEnabled -bool false

Now, you'll need to log-out and log back in. This should disable the display of the popup and character typed should start repeating when the key is held down.

If you ever wish to return to this behaviour, execute the following command-line in the Terminal.app:

defaults write -g ApplePressAndHoldEnabled -bool true

You'll need to log-out and log back in again for the setting to take effect.

iPhone X Activity and Health app: Doesn't work - shows spinning wheel instead

It really sounds to me like a connection issue, especially since we've established multiple apps being unable to read data from the Watch.

I would go through the process of unpairing and then restoring your Apple Watch to see if that resolves the issue. See: How to unpair and restore the Apple Watch.

If that fails you can call Apple Support as they can actually run diagnostics on your Apple Watch remotely (you will need to have your iPhone with you as well in order for them to do this). It doesn't take long to do and will help identify if there are any hardware issues.


Implement a large email archive on a Macbook Pro 13"

It really depends on what you're looking to optimize for, effort to implement or $$$ spent:

1) You could spring for Outlook for Mac which will know how to import your PST and will also make its contents indexable for spotlight.  Downsides include the $$$ and the memory overhead involved in launching Outlook when you want to get into the details of an old email you were looking for.

2) Use some conversion tool to get those emails into Apple Mail.  It will handle the quantity just fine (at least it does for my slightly smaller ~10G archive).  Spotlight integration is obvious here, but you also get quick view support when you use spotlight from a finder window.


Adding an IMAP account without saving emails locally in Mail 7.0

Mac terminal prompt's machine name becomes "bogon" after using traceroute

By some searching I found a solution to this problem.

First, change the DNS address in your network configurations to a better one, like google's 8.8.8.8.
Second, run sudo hostname theMachineNameYouWant in terminal.

The reason for this:

They say that when you are doing DNS lookup/reverse lookup, the DNS server can give your machine a host name, this function should be turned off for public DNS servers, but I don't know why the DNS server of my local ISP has it on.

Since my machine uses a router, so it has a IP like 192.168.0.x in LAN, I don't know why but when using traceroute, this IP will be sent to the DNS server for a reverse lookup, and since it is a reserved IP address, the DNS server returns a hostname as bogon, thus, changes my machine's hostname.

So what is bogon? Bogon means the type of IP addresses that should not appear in a traceroute, like a reserved IP address.

bogon on wikipedia.


In order to remotely control a Mac, say your desktop machine, you must first set it up for commands to be sent to it. To do this, launch System Preferences > Sharing on the Mac you want to control. Click the box next to Remote Apple Events, and set user restrictions if you need to.
Next, you will need the IP address. In System Preferences, switch to Network and locate your machine’s IP address. It should be something like, 192.168.0.3. Copy that address to proceed to the next step. You can also use the machine’s Bonjour name which can be found at the top of the Sharing pane in System Preferences. Its address will be spelled similar to this one: "smith-nancy-computer.local"
Now from another Mac, create your applescript like this:
tell application "Finder" of machine "eppc://192.163.0.3"
set volume 4
end tell

Sidenote:
Unfortunately I don't have a second Mac to test this on, so if anyone can improve this answer if it doesn't work, please feel free to make changes or add comments.


What is the blue section of a partition in Disk Utility?

The blue shaded area in the image provided is part of the Macintosh HD volume.

The blue shading denotes the used space on a volume.

The EFI boot system cannot be viewed or modified with any Apple-supplied GUI tool.


There are only 2 types of connector for iPhones/Pads; the old-style 30-pin & the new-style Lightning connector. The change to Lightning, for phones, is at iPhone 5; prior to that they were 30-pin.

The output of a phone/pad charger has only 2 variations, 1A for phones, 2A for pads. Any device needing 2A or less will work on a 2A charger, a 2A device on a 1A charger will charge, but very slowly.

Any recent Apple computer is capable of charging either a pad or phone directly over USB, using the detachable cable from a mains charger, as Apple incorporated a non-standard 2A capability into the ports. Older machines can charge phones easily, but pads only more slowly, as they don't have the full 2A capability.

However, there is no compatibility between a phone/pad charger & a laptop charger, without 3rd party hardware. Examples - https://www.twelvesouth.com/product/plugbug or http://www.supercompressor.com/tech/cabin-charges-your-iphone-with-a-macbook-charger
A phone charger cannot be pressed into service for a laptop, as it's not powerful enough.

So…
TL:DR is yes, it will work, so long as you're charging the phone from the laptop over USB, or directly from a phone/pad charger.
As you'd need to have the phone connected to the laptop over USB for connectivity, just using the USB->Lightning connector is sufficient.

If it fits, it works.


Increase size of sparsebundle for TimeMachine

Double-click the sparse bundle to mount the Time Machine Backups or Backup of <computer name> partition (but don’t select it). That may take a moment.
  Select the sparse bundle again, and click the Partition tab towards the top of the
  window.

  Type the desired size in the space provided, or, in the diagram that appears, drag the lower right corner of the partition all the way to the bottom to fill the volume, or drag it upwards to shrink it, click Apply and confirm.
  As part of the process, Disk Utility will do a verification of the data in the partition, so it may take quite a while. You can see the log of what it's doing by selecting Window > Show Log in the menubar.
  When done, and you quit Disk Utility, you may get an Operations still in progress message. As long as the log says "Partition Complete," it's done, so click Close.
  Eject the sparse bundle before starting the next backup.

Blinking folder icon - safeboot, recovery hd does not work

Did you do anything special before the problem showed up? Like performing an osx update? I'm asking because I experienced my SSD going completely dead after an osx update myself before.

It might be the disk is broken, especially indicated by the disk not showing up in internet recovery.

If you feel comfortable with it, I'd advise you to boot up a Linux live distribution of your choice and check if it is able to detect and mount the drive. If it's not detected, professional disk recovery services are likely your only chance. If Linux is able to mount or at least detect it, you should be able to repair it or at least rescue your data. There are tons of sources on how to repair/rescue hfs+ partitions from within Linux, such as this.

If you don't want to go this route, you can always head to your nearest Apple store and let them determine the issue. While they might not fix it (for free), you'll at least know whats going on and if data recovery is an option.


Does the iPhone 4S generate a spark or detectable electric signal of any kind when receiving a call?

To cut it short: This assumption is false.

Cellphone are not able to cause high voltage sparks required to light gas. Probably only if short-circuited.

Mythbusters investigated this problem. Their answer was that such accidents were caused by static charge on the person, not by cellphones.

This is important to notice as
"Petrol has a low electrical conductivity. This can cause a charge of
static electricity to build up as it flows through a pipe."[1]
When both the petrol and the person are charged, there is a potential spark discharge in the gap between.

Edit:

A BBC news article mentioned that research has been conducted on the matter by Dr Adam Burgess of the University of Kent. The publication is called:
‘Phantom Risk: The Curious Case of Mobile Phones, Fire and Body Static,’ Health, Risk and Society 9 (1) 2007 ISSN: 1369-8575 and available here.

My mac will not let me save word documents

The hint here is "... naming or permissions error on the destination volume." Word is telling you that it sees corruption/damage where you want to save the document.

And I'll bet you see it even if you try to save it to a USB key as well.

Microsoft is a great provider for those of us who do tech support for a living. What that error likely means is that something in MS Word (and possibly the rest of MS Office) on your system is damaged. The part is most likely in the part of Word that writes to disk.

What I would do is run the MS Word/Office installer and reinstall (or repair if that option is available) MS Word.

Failing that it could be that the temporary (recovery) file that Word creates for every document is damaged or that the preference file for MS Word is also damaged.
The former is here:

 /Users/<username>/Library/Containers/com.microsoft.Word/Data/Library/Preferences/AutoRecovery.

The latter is here:

~/Library/Preferences/com.microsoft.Word.plist

Trash all the autorecovery files and trash the .plist file and launch MS Word again. That should fix it.

If not you may actually have file system damage on your HD. In that case boot into Recovery Mode, launch Disk Utility and repair/verify the disk.


My System Preference window moved and isn't in the center anymore

In macOS Catalina you can use the following command in Terminal after closing System Preferences.app to delete the currently stored window position:

defaults delete com.apple.systempreferences "NSWindow Frame Main Window Frame SystemPreferencesApp 8.0"

This will delete the key including the window position.

Afterwards relaunch System Preferences.app and the key will be restored with a default position. The window will be centered in the East-West direction and slightly moved to the North. This is intended by Apple and indicates visual prominence.

In case the key name changes after a system update (e.g. to "NSWindow Frame Main Window Frame SystemPreferencesApp 8.1") you will get an error after entering the above command:

Domain (com.apple.systempreferences) not found.
Defaults have not been changed.

Then you have to search for the new proper key name by issueing:

defaults read com.apple.systempreferences

which will result in a long list:

...
NSQuitAlwaysKeepsWindows = 0;
"NSWindow Frame DestinationSheet" = "643 525 416 311 0 0 1680 1027 ";
"NSWindow Frame Identity Picker" = "673 573 357 263 0 0 1680 1027 ";
"NSWindow Frame Main Window Frame SystemPreferencesApp 8.1" = "9 476 668 548 0 0 1680 1027 ";
"NSWindow Frame NSNavPanelAutosaveName" = "463 333 799 448 0 0 1680 1027 ";
SecurityPrefTab = General;
...

The relevant key is the "NSWindow Frame Main Window Frame SystemPreferencesApp ..." key.

The "updated" command would then be:

defaults delete com.apple.systempreferences "NSWindow Frame Main Window Frame SystemPreferencesApp 8.1"


MacOS/Debian10 dual boot- how to delete unknown EFI partition?

You have two EFI partitions. Only one has the correct boot files. The other does not. You can try renaming a folder in the first EFI partition and see if this solves your problem. The commands are given below.

sudo disktuil mount disk0s1
mv /Volumes/EFI/EFI/BOOT /Volumes/EFI/EFI/NOBOOT
diskutil unmount disk0s1

If this does not solve your problem, then undo the above commands and try then other EFI partition. The commands are given below.

sudo disktuil mount disk0s1
mv /Volumes/EFI/EFI/NOBOOT /Volumes/EFI/EFI/BOOT
diskutil unmount disk0s1
sudo disktuil mount disk0s4
mv /Volumes/NO\ NAME/EFI/BOOT /Volumes/NO\ NAME/EFI/NOBOOT
diskutil unmount disk0s4

If this fixed your problem, then you should consider changing the label to something better than EFI Boot. And/or add an icon.


Disk utility has no option to expand HFS+ volume?

If you successfully shrunk the APFS container partition to create free space, then macOS and Windows can not be used to add this free space to any other partition without destroying the contents of the other partition. Other solutions involve moving or copying other partitions.

You can only expand a partition downwards. You can not expand upwards. You shrunk the APFS container partition, therefore the free space resides directly below this partition. The only partition that can be expanded to claim this free space is the APFS partition itself.

You need to destroy the HFS+ partition and recreate it. First, you will need to backup any files you want to save. There is third party software which claims to be able move a HFS+ partition, but this usually take a long time to compete. Also, you should backup your important files before attempting. I should point out once you have made a backup, then could just destroy and recreate the HFS+ partition and avoid using third party software in any attempt to move the partition.

Just so you know, I download as bootable iso for Gparted and created a flash drive with an APFS, free space and JHFS+ partitions. I was able to boot from the iso in VirtualBox and move the JHFS+ partition on the flash drive. So, yes there is free third party tools that can move a JHFS+ partition. However, after moving the partition, I used the command diskutil verifyvolume on the JHFS+ volume. The verify failed with the messages given below.

$ diskutil verifyvolume disk1s3

After the repair, I was able to resize the JHFS+ formatted partition to reclaim the free space immediately after the partition.

  Note: If your Mac is using hybrid partitioning, then you probably want to temporarily remove this hybrid partitioning before using third party tools such as Gparted. Once you have finished you could restore the hybrid partitioning. A good third party tool to enable and disable hybrid partitioning is gdisk.


Leave Apple Magic Trackpad 2 plugged in charging?

You should discharge your battery about once a month to recalibrate it. Other than that there should be no downside to keeping it plugged in. The battery charging mechanism is smart about not overcharging it.

See this page by Apple: Why Lithium-Ion?


Reverse search is not working on mysql terminal on my mac

Reverse search as triggered by Ctrl-R is a functionality provided by bash and which searches within the shell's command history. Once you start mysql you rely on the keyboard combinations available there, you can't use the bash shortcuts while mysql is running.

If you want to use reverse search with mysql you need a version with readline support compiled into it.


I've researched this topic myself, and everything I've found says that the HDMI port and/or Thunderbolt port on Macs is not meant as a display input. You can't use it for that purpose.

However, something that may work, if you're willing to spend money, is a capture card. I've used them for recording video game footage before. The one I use has a noticeable lag. It's split from the TV to the capture card, and what happens on the TV takes 1 or 2 seconds to display on the input from the capture card.

If you could find one without lag, or with very minimal lag, it'd be usable for gaming purposes. Of course, if you're trying to hook up something that doesn't need to be lag free, such as a movie player, or anything else that plays non-actively controlled media (actively-controlled media would be video games, and pretty much nothing else), you could do with a capture card that has some lag.

This is a capture card that advertises OS X compatibility: http://www.blackmagicdesign.com/products/intensity/

It has probably any input you could need. I'm not sure if it lags or not, as I have not used it. Also, you have to consider the fact that they may use proprietary software for recording. If they do, and there's no way to display a video stream without recording, it's probably not a good solution for you.

Some quick searching seems to indicate there is no noticeable lag with Blackmagic's Intensity capture cards. It also seems to suggest that their software can display without recording. I don't know if you can full screen it or not. Or if you can display a video stream in a program of your choice.

Edit: I just noticed on their site, they said it supports streaming. And doing so with "all leading streaming software" too. Which would suggest that it does provide a video stream, which you could utilize in a program of your choice, and also display in full screen.


iPad Air aluminum scuffed badly. Should I worry about it?

I wouldn't worry - looks like you got off without a scratched lens cover and only light cosmetic damage.

In general, Aluminum oxidation is a good thing as it seals the metal and protects. However, despite not being able to pin down the exact alloy that Apple uses, I know from experience that the iPad cases are not prone to oxidation even when deeply scratched or gouged.

I have never seen an iPad with structural or even cosmetic issues due to corrosion due to the anodized coating being scuffed. I have seen many iPads used in a marine environment and saltwater spray and/or the highly saturated air usually kills the circuitry inside far before the case can wear or corrode.

I'd say, clean up any sharp scrapes or cover them with a case and don't worry about the effects of the scratches.


How do I only backup data for specific apps on iOS?

Source:

Choose which apps to back up

Many iOS apps automatically back up to iCloud after you install them. You can change which apps back up and remove existing backups from your storage. Use these steps on your iPhone, iPad, or iPod touch.

iOS 10.3 or later:

Go to Settings > [your name] > iCloud.
If you use iOS 11, tap Manage Storage > Backups. If you use iOS 10.3, tap iCloud Storage > Manage Storage.
Tap the name of the device that you're using.
Under Choose Data to Back Up, turn off any apps that you don't want to back up.
Choose Turn Off & Delete.

iOS 10.2 or earlier:

Go to Settings > iCloud > Storage > Manage Storage.
Tap the name of the device that you're using.
Under Backup Options, turn off any apps that you don't want to back up.
Choose Turn Off & Delete.

When you confirm that you want to Turn Off & Delete an app, it turns off iCloud Backup for that app and removes all of its information from iCloud.

Some apps, like Voice Memos, are always backed up and you can't turn them off.


Signed iOS app "can't be opened because it is from an unidentified developer"

You've signed the IPA with an App Store distribution certificate, then not distributed through the App Store, so the certificate is invalid in the eyes of Gatekeeper and the file will be blocked. Use ad-hoc distribution if you wish to send the IPA file manually. Either way, macOS won't run IPAs as they're iOS app bundles.


Parallels VM: Is there a way to run a script on the host when launching a VM?

Absent somebody pointing out a way to do this within Parallels itself, here's a solution using only native utilities - thanks @user3439894 for suggesting a Launch Agent!

Create a /usr/local/bin/parallels_vm_starting shell script and chmod 755 it to make it executable:

#!/bin/bash

(
    echo "----------"
    date

    if /usr/bin/tty -s
    then
        echo "interactive"
    else
        # sleep for a bit to give things a chance to settle
        echo "background - let things settle"
        sleep 15
        date
    fi

    # Actions to perform when hosted VM starts up

    /usr/local/Homebrew/bin/brew services restart redis

    # etc. as needed

    date

) 2>&1 | tee -a /tmp/vm-startup.log

Create a Launch Agent file ~/Library/LaunchAgents/parallels_vm_startup.plist with this content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
        <string>parallels_vm_startup</string>
    <key>ProgramArguments</key>
        <array>
            <string>/usr/local/bin/parallels_vm_starting</string>
        </array>
    <key>WatchPaths</key>
        <array>
            <string>/Library/Preferences/Parallels/parallels_dhcp_leases</string>
        </array>
    <key>StandardOutPath</key>
        <string>/dev/null</string>
</dict>
</plist>

This will monitor the file /Library/Preferences/Parallels/parallels_dhcp_leases, which Parallels modifies when the VM starts (assuming the VM has networking enabled), and will execute the shell script when that happens.
Note: the DHCP leases file is regularly updated while the VM is up. If you only want to react to a VM being launched or shut down, monitor the file /Library/Preferences/Parallels/vmdirectorylist.desktop.xml instead.

Activate the Agent: launchctl load ~/Library/LaunchAgents/parallels_vm_startup.plist


In general, you can edit, create and enable/disable keyboard shortcuts using the Keyboard Shortcuts tab of the Keyboard preferences pane.


How can I change the default search engine in Safari?

The AnySearch extension allows you to set any search engine you want.

It achieves it by listening to the beforeSearch event, canceling the default behaviour and checking your settings for your chosen search engine. Then it puts your query into the specified search engine and displays the results.

You could, too, edit the host file, redirecting form any of the default search engines to the one you want, but that wont be so neat.


How does Messages determine whether the SEND button should be green or blue?

If the recipient's iMessage is unavailable, or yours, for that matter, the Send button will be turned to Green, showing that you'll send a SMS. When the iMessage service is available again, the button will be turned Blue, showing that you'll be sending iMessages instead of SMS.

So, if you want to make sure you'll always be sending an iMessage, although the service is unavailable, meaning that the recipient will receive the text whenever it's possible, just switch off the Send as SMS under Settings / Messages.


2nd HDD in Early 2011 MacBook Pro ejects during large file transfers, but only in OSX

The answer:

I took the 1TB HGST Travelstar 7K1000 and gave it a firmware downgrade.  HGST emailed me application to set the port to either, Sata I, II, or III.  Reducing it to Sata II solves the problem.

No more dropping.

Has somethgn to do with Apple/intels first venture into the Sata III world back then.  I used the less expensive Opti bay kit.  Not the more expensive Extreme they have created to solve the problem.

Works great and is plenty fast for a seconday drive.


MacBook Pro won't recognize my analog audio jack headphones. Help?

There seems to be a bug whereby if the headphones are plugged in when the MBP is put to sleep and are not present when it is rewakened, the headphones stop being recognized. The solution is to:

Unplug the headphones
Put the MBP back to sleep (close the lid; without an external display hooked up)
Plug the headphones back in
Wake the MBP by opening the lid.

This should fix the problem.


How do I delete photos just from my iPhone not my iCloud Photo Library

Unfortunately, Apple does not provide that information when you are about to delete a picture or albums. It would be nice if Apple would give us a Help option in the photos app that can also be removed if desired. Furthermore, I am not an expert on this subject but I will provide a sensible answer from my research, rather than making a comment that DOES NOT answer the question. But Hey, everybody is entitled to there opinions and comments.

So here it goes:

How do you eliminate a photo off your iPhone without eliminating it completely from my iCloud Photo Library and other devices?

You can’t, and it’s a little counter-intuitive as to why. You have to twist your head around to how Apple thinks of cloud storage for media. When you use iCloud Photo Library, the “truth” of your library is in the cloud—that means that the accurate, full, current state of all your images and other media are always stored on Apple’s servers, and the various places you can download or view images (Web, iOS, and OS X) are endpoints. (The only point in which that’s not true is when you have images that remain to be uploaded from an endpoint.)

Thus, if you delete an image in any associated app, you’re telling iCloud Photo Library to remove that image from its “truth,” which means to delete it from the central repository and sync that change to all endpoints. You can choose to only store optimized (low-resolution) media in iOS and OS X, but you can’t delete images in one place and expect them to remain elsewhere. And you can’t maintain separate local albums in Photos that aren’t synced. (In OS X, you can use alternate, non-synced libraries, however, choosing them when you launch Photos. In iOS, you can use alternate photo apps that can have their own libraries, too.)

If you want the ability to delete images from an iPhone or any device without deleting it from all your devices, you have to disable iCloud Photo Library and use another form of sync or another service, like Dropbox, Google Photos, or Amazon Cloud Drive.

How to identify a missing datastore for com.apple.securityd?

Resolution

  a. I have a crlcache.db reference that appears dead, but no number of deletion attempts makes it go away.

This was the root problem, but it was difficult to make it go away with any of the existing tools. The crlcache.db entry was ghosted in my Keychain Access application, so an entry still existed. While I had reset all of my passwords, I hadn't fully killed the Keychain. All the applications I listed were using the Keychain to find their information, hitting crlcache.db and then either retrying or throwing I had to manually remove both of these files (essentially a hard-reset of the entire Keychain):

~/Library/Preferences/com.apple.security.plist
/Library/Preferences/com.apple.security.plist

Diagnosis

It was very difficult to diagnose the issue because nothing would tell me which file did not exist. This comment, with its command that gathered bug information for Apple, was the most helpful. This produced a giant tar.gz with lots of diagnostic goodies that told me much more about what was going on. Make sure to run along with whatever application(s) is misbehaving at the time.

sudo sysdiagnose securityd

Among the many plain text debug output files it produced, there was a large one called fs_usage.txt, and when I opened it up, I could see 1000s of familiar entries

08:01:11.999993  getattrlist                            /private/var                                                                                0.000003   Twitter.3616
08:01:11.999996  getattrlist                            /private/var/db                                                                                0.000003   Twitter.3616
08:01:11.999998  getattrlist                            /private/var/db/crls                                                                                0.000003   Twitter.3616
08:01:12.000000  getattrlist            [  2]           /private/var/db/crls/crlcache.db                                                                                0.000002   Twitter.3616
08:01:12.000004  statfs64                               /private/var/db/crls

Once I saw that, it was clear the Keychain was still the issue, and my ghosted entry had to go. Lacking the knowledge of how to perform laparoscopic surgery on the plist files, I simply amputated and started over.


You must have a valid payment method in your account, even for free apps.


Bluetooth doesn't stay connected after update 11.2

Go into Settings > Bluetooth > MY DEVICES and tap on the Information icon ('I' in a circle) to the right of the device, then tap Forget This Device. Tap again on Forget Device (in red) to remove the device. Re-pair the device and see if it stays connected as expected. This has worked for me with other Bluetooth devices (I don't own a tune2air) that have developed intermittent connections.


iTunes is changing the number/order of tracks in an album when it loads into my iPod. I want the tracks to stay in order

I'm not sure why this is happening, but you can fix it by clicking on a track, going to File > Get Info (or ⌘ Cmd-I) and changing the track numbers back to the correct information.

To get the correct track number, you can try googling the album. Somewhere will surely have the titles and track numbers.


CPU completely occupied by strange programs with person names

Immediately disconnect from the Internet!

A possibly compromised system should not remain connected to a network or the Internet so as to stop any possible data breach! Even if a data breach has already occurred, the first step is to disconnect as a step to mitigate damages.
Power down the system and boot it from an external source that is outfitted with the tools to examine the infected disk and take appropriate action.
Run a malware scanner on your computer as malware process names are often randomised from a list. One of these should give you some indication of whether anything is wrong from a malware point of view:

Is it possible to improve the condition of MacBook battery showing "Condition: Replace Soon"?

Go to the Apple menu and choose "About This Mac"
Click "More Info..."
Click "System Report..."
Under Hardware, click "Power"
Under "Battery Information" you'll find "Health Information"
Under Health and Information you'll see "Cycle Count" and "Condition"

Cycle count can drive condition: over a certain numbers of charges and discharges condition will automatically drop. Given the age of your computer, my guess is you have a high cycle count.


How to check the progress of files moved from one place to another in terminal?

I found this https://github.com/atdt/advcpmv it adds the -g option to cp and mv which will display a progress bar.

Here's how I got it to work on El Captain:

Requirements:

Xcode
wget (you can install wget with brew or MacPorts)

Then:

wget http://ftp.gnu.org/gnu/coreutils/coreutils-8.21.tar.xz
tar xvJf coreutils-8.21.tar.xz
cd coreutils-8.21/
wget https://raw.githubusercontent.com/atdt/advcpmv/master/advcpmv-0.5-8.21.patch
patch -p1 -i advcpmv-0.5-8.21.patch
./configure
make

At this point you will have cp and mv binaries in src/ give them a try and if you don't have problem with them you can move them to /usr/local/bin.

You may also rename the two binaries to cpgres and mvgres (or other unique names) so that you can use the standard cp/mv commands also.


Canon Selphy CP780 Printer for MacBook Air

Perhaps you should try the GutenPrint print drivers. These open source drivers work for a huge number of printers, the Selphy CP770 and 790 are listed as supported so either of those might work.

The drivers work with all versions of OS X.

How do I calibrate the colors for two monitors for web development?

There some hardward-based display calibrators that usually cost $80 and up. Some names are "Datacolor Spyder3Express",  "LaCie Blue Eye", "PANTONE huey".

An important issue with calibration for the web is to:

Calibrate with gamma 2.2. If you're on Snow Leopard, especially if you started with it on the Mac when you bought, then it will be gamma 2.2 already. But if you use Leopard or calibrated on it, you might have gamma 1.8, which is not standard for web (and doesn't fit Windows, which also has 2.2).
Learna about sRGB color profile, which was build for CRT monitors back in the day. Many browsers don't support embedded color profiles for images (Safari does support, though), which means they'll render uncalibrated, which means they'll be rendered in your (and other visitors') monitor' profile, which might be close to sRGB.
You should preferably export all your graphics without profile or with sRGB profile for them to display most propertly with all brosewrs.
Calibrating with Mac OS X build-in software calibrartion is possible but might require several iterations to get right. If your display has non-LED backlighting you should let it work for about 10 minutes before calibrarting or otherwise judge its colors, while the lamp warms up.
You're better off try to compare some images that have embeeded sRGB profile and the same that isn't  and see if the colors match in browser.

Resources:

A good place to test your monitor (but not calibrate color profile) is: http://www.lagom.nl/lcd-test/
sRGB and other color profile information: Has great tests with hover-switching images to see how different profiles and no-profile images display on your monitor. http://www.gballard.net/psd/srgbforwww.html
The above website has specific instructions on calibrating a Mac: http://www.gballard.net/photoshop/hardware_calibrate_monitor.html
Calibration theory and some test images (even though more photography oriented): http://www.normankoren.com/makingfineprints1A.html
Some Mac OS calibration process tips at http://www.khulsey.com/monitor_calibration.html

Also, S-IPS panel monitors have more consistent color reproduction at different viewing andles. If you have regular TN monitors, you might have a problem see them both at the same color from the different angles that you see them, even if each one is calibrated 100% when viewed hean-on.

And yes, it might take huge amount of time and a lot of disappointments, so be patient.


How can I open the 2011 MacBook Air without damaging the screws?

You cannot safely remove it without the proper tool and the correct touch. You want to place the driver on the tangent to the case (the screws enter at an angle - not vertical compared to the keyboard plane.

iFixit.com and other places sell the pentalobe tool for less than $15 and it's money well spent to avoid needing to get Apple to replace the screws should you strip them.


Upgrading an old mac mini intel 1.1 for Lion

Short answer: No, it will not work.

Long answer: Lion requires a 64bit processor and the Yonah processor on the mini1,1 still is partially 32 bit. You will NOT be able to boot in to Lion because you cannot boot a 64 bit kernel. However, it is possible to use a separate disk to boot into a custom boot loader and then load Lion from there (much like trying to get a MacPro1,1 to boot Lion). This is a definite hack, and not something I would recommend to anyone, especially for a super-low-end machine like this mini. It will not be happy.

Also, this machine has a SATA-I interface, so even with an SSD in it, it will still be slow.


How can I sync Mac Calendar with my own server?

Launch System Preferences
Select Internet Accounts
Select Add Other Account…
Select CalDAV account

You can then configure the calendar to synchronise with. The calendar must support CalDAV to work with macOS.


Fastest way to migrate file by connecting two Macs together

The fastest way is to connect the two computers using Thunderbolt. This will give you 10 Gbps of bandwidth, which is 10 times what you would get from the ethernet port on the 2011 MacBook Pro.

Note that if you have only one drive in your old MacBook Pro, you'll technically be limited by the speed of that drive when transferring. I.e. if you have a 6 Gbps drive, you'll only be able to transfer at that speed - which will probably use approx. 7 Gbps of Thunderbolt bandwidth. If you've got the two drive mod for the old MacBook Pro, you'll theoretically be able to use the full bandwidth of the Thunderbolt connection.

You'll need a Thunderbolt to Thunderbolt cable and a Thunderbolt 2 to Thunderbolt 3 adapter cable to connect the two Macs. As Thunderbolt 2 is backwards compatible with the original Thunderbolt, this will allow you to link the two Macs together. Then boot up the old Mac in Target Disk Mode (hold down the T key while booting) - and you can use it as a data source in Migration Assistant.

If you haven't got those cables lying around, chances are that it is probably faster to just use Ethernet rather than waiting for cables to be delivered. WiFi is definitely the slowest approach here.


How do I delete imap email accounts without opening Mail

Go to Settings -> Internet Accounts -> Delete / Disable your email.


Here's a guide to get you going again.

Not sure if your question needs to be closed as too broad / too much 20 questions - technical support, but following Apple's erase and install process should fix this at the cost of any data you still have on that drive.

Can't start Mac in recovery mode - only get folder with question mark instead


View all ratings and reviews in iTunes for PC

I am demonstrating the steps using iTunes for macOS. They should be similar for iTunes for Windows.

Make sure you are logged in with your Apple ID in iTunes. Access your account from within the Podcasts Store.

On your Account Information page, under Settings section you can find Reviews and Ratings section. Click on Manage link in front of it to view all your reviews and ratings in one place.


No Plus Sign Button or Edit Button in IOS Contacts App

You may be looking at a subscribed contacts list, rather than one of your own that you have read/write access to.  Go 'back' all the way to list you contacts accounts, and ensure you are actually looking at your own contacts.


Cut, copy, and paste.

According to Apple should work as follows:

  Find the text you want to edit in a note, email, web page, or other app. You can select a word by double-tapping it, and select more or less text by dragging the grab points. Then tap to cut, copy, or paste. To undo an edit, shake iPhone, then tap the Undo button.

However, in this particular case it appears that Facebook is creating a HTML 5 Web App/ page and is using JavaScript or similar functionality to prevent selection of text.  When trying to view the page on a Mac/PC text will also not be selectable "that is not in the pictured text box" for copying.

In this example pictured below the text "Photo" nor "No file chosen text" nor even the "Update Status" text on the top of the page can't be selected even on a Mac.

The select-ability of text on a website does depends on the sites implementation details. If a site chooses to disable text selection the iPhone's browser will obey the sites request, and will not give you the ability to select text.

For the Facebook example text is really not select-able  even on the Home wall page.  If you really want to copy text from Facebook pages try opening the desktop version of the site on your iPhone. The same rings true for other sites that may be offering custom mobile web pages that may limit text selection.


Why is Target Display Mode via Thunderbolt so unreliable for me?

If you can touch the cable and have it drop in and out, I would say you either have a bad cable or bad connector (or both?) on one of the computers.

Try your setup with a different cable and see if you get the same result.

Good luck!


I found an article at TUAW which talks about the Passware Kit Forensic 11.4 software designed to 'crack' Filevault 2. However, this software can be foiled by two simple configuration points: 1/ turn off automatic login & 2/ shutdown the Mac instead of sleeping when you travel. In addition, the software requires physical access through a firewire or thunderbolt port so your computer cannot be touched through remote access.

The Privacycast site has this detailed article for your edification.

Seeing that you have a MacBook Air, with its astoundingly brief startup time, I'm not sure why you keep it in sleep mode whilst traveling. I never put my MBA to sleep unless I'm at home. If somebody steals my MBA while I'm home, I have a substantially larger problem on my hands.


Found these on the manufacturer's web site:

How to know Magic Mouse 2 is charging properly?

Unlike the first generation Magic Mouse, there is no indicator present on the Magic Mouse 2 that would indicate the charging status.
But if you have access to a Mac (which is with which you are most likely using your Magic Mouse), you can use it to check if your Magic Mouse is charging.
Start by pairing your Magic Mouse to your Mac and checking the battery status in either one of the following places:

Click on the Bluetooth icon towards the right of the macOS Menu Bar. Hover the mouse pointer over the entry corresponding to the Magic Mouse and see the current battery charge level.

Go to System Preferences → Mouse and look for the current battery charge level at the bottom of the window.

Now charge your Magic Mouse 2 for a little while which you can do either using a wall outlet or Mac. Disconnect and check the charge status again to confirm if the Magic Mouse is indeed charging.
Alternatively, you can have the Mouse System Preference pane open and connect the Magic Mouse 2 using the Lightning cable, and the battery indicator would change to show that the Mouse is charging.
