Brother iPrint&Scan App Crashing on MacBook Air M2 (macOS 14.5)

That cleaner app might have caused a problem.

Unfortunately, resolving corruptions can sometimes involve a reinstall.

I’d get a backup here first, if there's not a complete and current backup already available.

I’d next boot into Safe Mode, test the scanning, then reboot normally, and test again. This to see if the app starts working. This sequence can un-do damaged caches.

If not… Please download and run (free) EtreCheck, and share the results to the clipboard. Then open a new reply here, and press the Additional Text button that looks like a printed page, and paste and post the hardware and software configuration report here. From that, we can get a little more detail about what is installed and what is running here.

Remove the add-on security apps, remove the add-in battery tool, and remove the cleaner apps (I don’t see anything called PrettyClean, but I do see CleanMyMac), all per the vendors’ instructions, restart, and test again.

Given what is installed, this may well be headed for a backup and reinstall.

This is with the app from the app store? Or the app downloaded from Brother website?

Any add-on VPN apps, add-on security apps, add-on anti-malware apps, add-on cleaners, or similar add-ons?

Which model Brother printer?

Is the Brother printer firmware current?
