Boot into Safe Mode

Restarting your Mac into Safe Mode can troubleshoot whether other third-party apps are interfering with your app's functionality. It uses the bare minimum of your Mac's resources, loading with only the files and apps it needs to run. Therefore, no login items, extensions, or apps that aren't essential will be started.

Boot into Safe Mode to fix app crashing

Note that the way to enter Safe Mode is different on Intel and Apple Silicon Macs. Here's how to do it.

On Apple Silicon (M1 & M2) Macs:

  1. Turn off Mac and wait for 10 seconds.
  2. Press and hold the power button until the startup volumes and Options icon appear.
  3. Select your startup disk.
  4. Press the Shift key and click "Continue in Safe Mode."

On Intel-based Macs:

  1. Shut down Mac and wait for 10 seconds.
  2. Turn on your Mac, then immediately press and hold the Shift key.
  3. Release the key when seeing the login screen.
  4. Log into your Mac.

Once in Safe Mode, check if the app runs well. 

If your app no longer quits unexpectedly, reboot your Mac normally and disable your login items and maintenance apps like VPN, anti-virus, etc.

If the "App quit unexpectedly" issue recurs, continue reading the next fix.

Clear app caches

Another way to fix "MacBook Air applications quit unexpectedly" is to clear the cache files of the crashed app. These cache files contain temporary data saved to help your apps load faster in the future, including HTML files, images, videos, java scripts, etc. It's safe to delete them, as they will be regenerated the next time you use the app.

  1. Open Finder.

  1. Launch Finder.
  2. Select Go > Go to Folder from the menu bar.
  3. Paste ~/Library/Preferences into the search box and hit Return.
  4. Delete the preference file regarding the app that quit unexpectedly.
  5. Empty the Trash.

Free up memory resources

Running out of memory is also a common reason behind the issue of "App quit unexpectedly" on macOS Ventura, Monterey, etc. So, it's worth trying to free up your memory space. You can use the built-in app Activity Monitor to check and close the unnecessary processes that are eating up your memory resources.

Fix application quit unexpectedly on macOS Big Sur and others:

  1. Open Activity Monitor from the Applications > Utilities folder.
  2. Select the memory tab.
  3. Locate the processes that are using the most memory space.
  4. Select one and click the ( ⤬ ) button.

Update or downgrade macOS

Sometimes, app crashing is rooted in the bugs in your current operating system and it may have been addressed in a newer point release. Therefore, you should check whether there's a new update available to your Mac.

If the app quits unexpectedly on macOS Ventura or later, install the available release from System Settings > General > Software Update.

If the app quits unexpectedly on macOS Monterey or earlier, update macOS from System Preferences > Software Update.

Suppose you find no new update or the app keeps crashing after the update, consider downgrading macOS to a stable version where your apps work properly.

Reinstall macOS

If it's still impossible to use your Mac without apps crashing on Sequoia or earlier, try reinstalling macOS. To get the job done, you need to restart your Mac in Recovery Mode and click the "Reinstall macOS" button. This should not erase data on your Mac unless you choose to do a clean reinstall with all data wiped.

Hopefully, your app no longer quit unexpectedly on Mac. Please share this post if you find it helpful.
