Does reinstalling an offloaded or deleted app restore the exact same version or the latest App Store version?

2026-08-23T03:20:00Z

I understand the difference between removing apps on iOS/iPadOS: offloading removes the app's binary but keeps its local data, whereas deleting removes both entirely. I also know that redownloading is tied to my Apple Account, so I won't be charged again for paid apps.

However, I am curious about the specific version of the application that gets restored.

When I reinstall an offloaded or deleted app, does the system fetch the exact same version that was previously installed on my device, or does it automatically download the latest version currently available on the App Store?

Does disabling an app in "Allow Background Activity" apply system-wide or per-user?

2026-08-22T02:55:53Z

Under macOS System Settings → General → Login Items & Extensions, there is a section for Allow Background Activity where you can toggle background activity for installed applications.

If I disable an application using this toggle, is the change reflected system-wide across all user accounts on the Mac, or does it only apply to the currently logged-in user profile?

How to completely remove Python from Mac?

2026-08-22T01:14:46Z

A few months ago I installed Python from the python.org website. I want to completely remove it. How to do this? I downloaded version 3.13 from the macOS installer link.

Is there a way to edit GarageBand project files (.band) directly?

2026-08-21T16:49:50Z

I want to know if .band files can be edited directly, like using a hex editor, so I can insert effects or customize instrument patch settings without using the limited set of controls provided in the GarageBand UI. I don't know if there's any specialized software that can edit GarageBand project files directly through.

This specifically applies to projects created in the iOS version, but I think that the Mac version uses the same file format.

I have used hex editor programs in the past, but I don't understand the file format of GarageBand projects.

Does locking an app on iPadOS prevent it from running, or only from being opened? [closed]

2026-08-21T01:42:49Z

Since iPadOS 18, one can lock an app by touch-and-holding its icon and choosing Require Face ID / Touch ID / Passcode. Per Apple's documentation, this requires authentication to open the app, and the app's content is hidden from Spotlight, notification previews, Siri suggestions, etc.

Does locking an app actually prevent it from running in the background, or does it only gate the act of opening/viewing its interface?

My practical problem is that I want to prevent an app from running without unloading or uninstalling, and I want to know if locking it is a solution.

on macOS 15 I want to reconcile du and df command results to assess my remaining space for files

2026-08-11T18:24:33Z

Filesystem        Size    Used   Avail Capacity iused ifree %iused  Mounted on
/dev/disk3s1s1    995G     18G    113G    15%    427k  1.1G    0%   /

sudo du -xHh |less

reported 418G / albeit there was a ton of "Operation not permitted" on some directories in my home folder and outside of that.

I expected half a terabyte to be available but df claims it has only 113G. Mac->About reports 1/2 TB expected

UPD20260817 this is a similar Why do I get different Available/Used spaces with Disk Info and df? question that barely has any useful answers: I don;t have time machine turned on, not recently anyway

Another related question albeit about an external hdd External hdd: Difference "Get Info" Available space and "About This Mac - Storage

And here seems to be a detailed article on the subject https://eclecticlight.co/2023/04/17/the-finder-confuses-with-wildly-inaccurate-figures-for-available-space/

Unable to access macOS 15 Sequoia SMB shares from Windows 10

2025-03-30T20:22:44Z

I've tried accessing my macOS 15.3 SMB shares from Windows 10 without success. "Windows sharing" is enabled in macOS.

I get a login prompt but it says the credentials are wrong every time. I know they're not.

What I tried:

Username with and without workgroup, i.e: WORKGROUP\username and username
Connecting using smb://{ip address, mDNS hostname}, \\netbiosname, netbiosname in Explorer's address field... Every variation I could think of.
Connected to other SMB shares on the network, e.g. \\rpi.local, which worked
Connecting in the other direction (from macOS) which I could not make work either

What else is there to try?

Can't create Sierra installer - installing macOS gives a bug with -200 Seconds

2024-10-29T19:30:20Z

I tried to download macOS Sierra from Apple’s website, but because my new MacBook is on Sonoma, I can’t run the Sierra package to create a bootable USB flash drive like it’s mentioned by Apple.

I also can’t run the installer on my old MacBook on which I want to install Sierra, because it can only boot in recovery mode.

How can I create a Sierra installer or otherwise install Sierra on my old MacBook?

Face ID no longer works after activating Stolen Device Protection

2024-07-12T22:20:22Z

The Face ID feature on my Apple iPhone 12 Pro no longer works after activating Stolen Device Protection. I can't even reset face ID in security settings either.

According to Apple website:

When Stolen Device Protection is enabled, some features and actions have additional security requirements when your iPhone is away from familiar locations such as home or work.

However, I am at home on my home network. So I tracked down some info from Apple about how to fix this. The Apple website also instructs users to:

Go to Settings, then tap Face ID & Passcode.

Enter your device passcode.

Tap Stolen Device Protection, then turn Stolen Device Protection on or off.

However when I attempt to disable the Stolen Device Protection, the Face ID kicks in and tells me 'Face not recognized'

I attempted to reset my Face ID, but again, the Face ID kicks in and tells me 'Face not recognized'

What can I do to disable Stolen Device Protection and restore the Face ID on my iPhone?

Running iOS 17.5.1 on iPhone 12 Pro

How can I solve display dim then system sounds the charge chime once per minute while charging?

2024-05-28T01:15:43Z

I'm experiencing an issue where exactly every 60 seconds, the screen briefly dims, then brightens, then beeps. I don't care about the dimming/brightening, but the beeping is maddening.

It happens while charging using a new (non-Apple) Magsafe3 connector I bought, connected to a 96W Apple power adaptor. This combo otherwise seems to charge fine.

It's a 2022 M2 Max Macbook Pro. Ventura 13.6.3 (22G436)

After some research I've discovered:

the screen dimming behaviour can be disabled in settings, "Slightly dim the display on battery"
the beep is called the "Power chime".

So now the question is how to disable the power chime. The actual file is at /System/Library/CoreServices/PowerChime.app/Contents/Resources/connect_power.aif but I'm not able to modify/remove it.

Can I fix this behaviour or at a minimum prevent the sound?

Shortcut Input from Spotlight

2024-04-03T16:21:00Z

How can one write a shortcut that receives input from Spotlight search GUI (e.g. command+space)? I'd like to press command+space and type "ticket 12345", then have the shortcut generate the URL and open it in Safari. I've done this for years in Alfred with their custom workflows, but I'd like to do it in Spotlight too.

For example, I want to be able to use Spotlight to open a webpage for a specific support ticket number. The URL for the support system can be broken into a base URL and a parameter. I've created a shortcut called, "ticket" that I can run from Spotlight, but that shortcut has to open a window to ask for input.

On the command line this can be accomplished with the following syntax.

shortcuts run ticket <<< 121345

I'd looking for a way to accomplish the same thing when entering text in the Spotlight search field (command+space).

Port forwarding on macOS Sonoma 14.1.1 (23B81)

2023-11-29T23:30:58Z

I would like to setup port forwarding on my MacBook, but I don`t get it working, even after studying a lot of questions here and other blog posts.

I have some SSH tunels opened from another machine to my MacBook to be able to access other services via these tunnels. The tunnels are working fine. I checked this with nc -z 127.0.0.1 <port> and even with cURL.

To be able the use these tunnels transparently, I assigned each system a custom IP address via /etc/hosts.

gitlab.acme.com    100.0.100.100

To forward all trafic from 100.0.100.100:443 to 127.0.0.1:30030 I wrote the following rule:

rdr pass proto tcp from any to 10.0.100.100 port 443 -> 127.0.0.1 port 30030

But I am unable to apply this rule. My last attempt was to put this rule in /etc/pf.conf:

scrub-anchor "com.apple/*"
nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"

rdr pass proto tcp from any to 10.0.100.100 port 443 -> 127.0.0.1 port 30030

dummynet-anchor "com.apple/*"
anchor "com.apple/*"
load anchor "com.apple" from "/etc/pf.anchors/com.apple"

Any idea why this doesn't work?

Unix command to save QuickTime Player recordings into custom folder

2023-08-09T08:41:51Z

Using MacOS Ventura 13.5

Is there a Terminal command for macOS to specify a custom saving directory for QuickTime player videos?

For screenshots I use:

defaults write com.apple.screencapture location "<path></path>"

What would be the equivalent for quick time videos/recordings?

ps aux | grep com.apple.quick yields these paths for QuickTime:

/System/Applications/QuickTimePlayer.app/Contents/XPCServices/com.apple.quicktimeplayer.SharedPrefsVendor.xpc/Contents/MacOS/com.apple.quicktimeplayer.SharedPrefsVendor
/System/Library/Frameworks/QuickLookThumbnailing.framework/Support/com.apple.quicklook.ThumbnailsAgent

Tried to modify it to my needs:

defaults write com.apple.quicktimeplayer.SharedPrefsVendor location "~/Desktop/video_recording"

to no avail.

Using the UI. Upon each screen recording I have to select the custom target folder regardless of having clicked on "Remember Last Selection". The 2nd time I try to record the screen, it no longer saves the recordings in the specified folder.

Steps to activate "Remember Last Selection"

QuickTime Player > File > New Screen Recording > Options > Remember Last Selection

Does iCloud Passwords enable access to iCloud Keychain passwords?

2023-08-08T03:10:40Z

As a MacOS user, I enjoy the native password manager (iCloud Keychain), however, sometimes it is necessary to hop on a Windows browser.

Does iCloud passwords sync passwords from Keychain? Ideally, the answer would be yes.

Please to start the answer with a Yes or No. Thank you

Why would download history appear blank even though I save a file?

2022-09-09T19:57:11Z

I ran this command in Terminal on Monterey 12.5.1:

sqlite3 ~/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV* 'select LSQuarantineDataURLString from LSQuarantineEvent' > ~/Downloads/downloadhistory.txt

It saved the file as expected, and despite me running it again in terminal after saving a jpeg file, it was still blank.

Why is this?

I disabled Spotlight, could that be a reason?

Why would the output of this file be empty even after saving 4 JPEG files from www.bbc.co.uk, normally this command would display a list of files saved from URLs.

M1 Mac Mini FaceTime with external USB microphone

2022-08-12T15:59:50Z

I have an M1 Mac Mini. I have purchased a Logitech C920 webcam/microphone to be able to make FaceTime calls. The microphone works when I use Photobooth or Quicktime to record a video. It also shows up in the sound panel of system preferences with the audio indicator moving up and down as I make noise.

As soon as I make a FaceTime call the microphone stops working. I've checked in the video menu on FaceTime that the right devices are selected but no audio.

I've also tried to create a Aggregate device in the Midi tool as suggested online but that hasn't worked. I've rebooted the machine several times, tried different USB ports but still no luck. It appears to be a specific issue with FaceTime as the other apps I've used have worked great.

I'd really appreciate any kind of suggestions to help resolve the issue.

Creating APFS external USB thumb drive with macOS 10.12.6 Sierra

2022-08-11T01:28:15Z

Trying to create an external USB thumb drive to run macOS Monterey from but first needs to be APFS, using macOS 10.12.6 Sierra; I don't have an option from Disk Utility to format with APFS. I followed instructions using this code:

diskutil apfs createContainer /dev/nameofmydisk

but I got an error:

diskutil: did not recognize APFS verb "createContainer"; type "diskutil apfs" for a list

I did type list and got:

Usage:  diskutil [quiet] ap[fs] <verb> <options>
        where <verb> is as follows:
     list               (Show status of all current APFS Containers)
     deleteContainer    (Delete an APFS Container and reformat old disks to HFS)
     deleteVolume       (Remove an APFS Volume from its APFS Container)
     unlockVolume       (Unlock an encrypted APFS Volume which is locked)
diskutil apfs <verb> with no options will provide help on that verb

I am not sure what to do from then on and what this all means.

Basically, I do not want to update my OS on my computer, I want to run Monterey from an external drive USB thumb since it'd be easier to transport, and basically, because this is what I have at the moment because I don't actually care about having a new version of OS except for the fact that there are some tasks I can't perform on my Mac because of the OS is too old, and those tasks are not as relevant to me as it is to preserver my current system as it is.

As an example, I can't connect/transfer files to my new iPhone 13 through the Mac because the iPhone 13 requires to have at least a specific version of iTunes that I can't install on Sierra and a few other ones.

My machine is a MacBook Pro 2016 15".

Bluetooth keyboard connecting to MacBook Pro even though Bluetooth is disabled

2022-07-09T00:59:12Z

I have an Apple Bluetooth keyboard and trackpad that I share between two MacBook Pros (one personal, one from my employer).

I keep Bluetooth disabled on whichever laptop I'm not using, and the keyboard and trackpad will usually automatically connect to the other laptop.

However, some days the keyboard (and the trackpad, on rarer occasions), still re-connects to my personal MacBook Pro (MacBookPro11,4 on macOS 12.4), even though Bluetooth is disabled. System Preferences, Control Center, and running bluetoothd all show that Bluetooth is disabled, yet the phantom connection persists.

This behavior started occurring after I did a clean install of macOS Monterey in October 2021, and has persisted across subsequent updates (currently running macOS 12.4).

I solve this by toggling Bluetooth on and back off, after which the keyboard is disconnected (and will connect to my other MacBook Pro). But I'm baffled by this "phantom" Bluetooth connection, and would love ideas on how to investigate this further.

External Keyboard Layout does not match shown on System Preferences

2022-06-26T17:24:20Z

I have a MacBook Air M1 2020 on Monterrey 12.4.

I've just bought the Logitech ERGO K860, which has an ISO layout.

I had a problem that was recognized as ANSI, but I could solve that.

I could set it with the layout I wanted (Latin America), but I am having the problem that the shown layout at the configuration does not match with the expected when using the keyboard.

Particularly, the keys <, > and |, ° are swapped.

The first one works when pressing the key next to 1 (ie, the first key of the number rows) and the other with the one between the Z and the left Shift. This should be the other way around.

How to make links open in a virtual desktop browser instead of the second screen?

2022-04-12T20:03:58Z

When I use a monitor with my Mac, it's to watch videos and multitask. I'd have a Chrome window open on my main screen in a virtual desktop and another Chrome window open on the monitor. When I switch to another virtual desktop on my main screen, then open a web link, OSX always opens it in the monitor instead of the other virtual desktop. I interacted with the virtual desktop Chrome window last. How can I choose to open links in the virtual desktop?

How can I use my SSH key with TouchID so that don't have to type in my passphrase each time, but still required my finger print at each log in?

2021-12-05T07:47:04Z

I am trying to use my ssh key with touchID. As others suggested here, I ran ssh-add -K ~/.ssh/[my-private-key] and modified my .ssh/config with

 Host *
   UseKeychain yes
   AddKeysToAgent yes
   IdentityFile ~/.ssh/id_rsa

which works and makes my key available from the Keychain however it doesn't force me to provide my fingerprint. I would like to force the usage of TouchID to unlock my key every time when I try to ssh in, or at least once after opened the terminal client.

How to set several Siri triggers for the same action (automation)

2021-02-22T11:02:04Z

I am someone that is pretty forgetful and have the tendency to not remember exact sentences that trigger automations on the Shortcuts App.

This leads to me having to open the app every time I want to trigger an automation to see what's its name. Since I have to open the app and see the actual sentence, I often just click it instead of just telling Siri the sentence.

I would like to set several sentences as the triggers for Shortcuts actions so that I can associate more generic sentences to the correct action.

Example:

I want to preheat the car.

- "Hey Siri, preheat the car."
- "Hey Siri, warmup the car."
- "Hey Siri, I'm going to drive."
- "Hey Siri, heat the car."
- "Hey Siri, cooldown the car."

All of those sentences should trigger the same action. So can I define several sentences as a trigger for the shortcuts when interacting with Siri?

Or, is the only input going to be exactly what you type in the name of the shortcut action?

"Your computer restarted because of a problem" when installing macOS Big Sur in external SSD?

2021-01-11T04:58:31Z

I have a 21.5 inch retina iMac (2017) which has a malfunction internal SSD, so Ive been using it with a SAMSUNG external SSD connected via USBC/Thunderbolt port to the iMac.

This has been working for a couple of years now, the problem is that I was on Mac OS Mojave and when I want to update either to macOS Sierra, HighSierra or Big Sur, the installation process fails and enters in one of the following scenarios:

Message "Your computer restarted because of a problem" when installing, this generates an infinite loop and the installation is never finished.
Just a infinite loop, for example when is in "Installing software update X%" it restarts and enters in a infinite loop.

I've tried installing macOS with a Bootable USB and with a Software update from Mac OS Mojave, none of this works.

Is there anything that I can do? If I go and install Mac OS Mojave, everithing goes well.

Also is important to mention that anytime I try to do a bootable USB installation, I erase the SSD to "AFPS" and rename it to "Macintosh HD".

Thanks in advance

Green and white lines on screen of a macbook pro

2020-12-30T19:53:50Z

my Macbook pro 13inch, Early 2015 has the problem you can see in the picture

I take that to the support, they told me the screen was broken, so they replaced it, but the problem is still there. Now the weird side of the story, that issue is there just after the login screen. If I connect the macbook to an external display, both the internal and exernal starts to be well visible again!

Another strange thing is that I tried to wipe everything, formatting the entire disk and installing a brand new Catalina os (I had Sierra before). All the installation went smootly in the recovery suite (without the external display connected), and the initialization of the os as well. But, after the desktop appeared, the problem was back there.

When the hdmi cable is connected, the screen works perfectly fine, as you can see here

I tried to reset NVRAM with the P R option cmd combination I tried also to reset the SMC with shift ctrl option combination

Nothing seems to have any effect.

Any idea? Thank you

Can I search for my library in Apple TV app on macOS?

2020-12-17T23:56:46Z

In Apple TV app on my Mac I have a number of my video files in the library area for quick access (more than 50) but when I go to search in the search bar I immediately get taken to what Apple has for download.

I don’t understand why I can’t search my content first or exclusively.

Is it possible to find what I have in the library section?

How to Map f2 to Ctrl u in Excel (to make cell editing easier)

2019-09-08T04:26:12Z

Just upgraded to High Sierra on my MacBook air 2011. Unfortunately my Excel keyboard shortcuts have stopped working - I was using Karabiner to map F2 (usual windows edit key) to use ctrl u, which makes it easier to use excel. I had to also move to Karabiner-elements, as the version I was using isn't compatible with High Sierra. I have attempted to write a .json file to setup a complex_modification, but it doesn't seem to work - the event viewer just shows the f2 key Im using MacOS 10.13.6 Excel for Mac 2011 version 14.7.7 Karabiner Elements 12.6.9

The code I wrote is:

{
    "title": "F2 change to Ctrl U",
    "rules": [        
        {
            "description": "F2 change to Ctrl U",
            "manipulators": [
                {
                    "type": "basic",
                     "from": {
                        "key_code": "2",
                        "modifiers": {
                            "mandatory": [
                "fn"
                ],
                "optional": [
                         "any"
                        ]
                        }
                    },
                     "to": [
                        {
                          "key_code": "u",
                          "modifiers": [
                            "left_control"
                          ]
                        } 
                    ]
                }
            ]
        }
    ]
}

What am I missing? Thanks,

Is there any difference between Macs sold in China and US except the Taiwan flag?

2018-08-10T07:58:00Z

I wonder if there is any more difference between the Macs sold in China and USA, except that Chinese models don't show the Taiwan flag (🇹🇼), as explained in this question.

I'm in China and am considering buying it, but wonder if it is fine to buy it here or move to another country (not necessarily USA; countries not having such restrictions such as Japan are fine) to buy it. I would not like to find any regional restrictions only after I purchased it.
