MacBook Pro M1 apps (Safari, Slack, Trello, Apple Mail, Adobe CC) keep quitting unexpectedly all the time

Hi carl-m,

Welcome to the Apple Community.

Big Sur was a major upgrade.

Sometimes non-Apple software can cause issues.

Unnecessary anti-virus software is a major offender.

Seems that Chrome has been found to cause issues, too.

Wondering if you have updated all necessary non-Apple apps to versions that are compatible with Big Sur.

(To get rid of any unnecessary apps, it is best to use the uninstaller from the app's developers.)

Cheers :)

I have been having this same exact issue and it's causing me to restart every time it happens. When one of the apps 'quit unexpectedly', it seems to have a knock-on effect on other apps (eg Safari, Firefox, Chrome -I've been trying a few different browsers independently to try to pinpoint the problem) and makes other apps crash as well.

I don't think it's a memory/storage issue as I literally don't have anything else installed; and the problem was there within the first week or so.

All my apps and Big Sur are up to date. Safari was one of the apps that crashed so I wouldn't expect this given it's an Apple app.

I need all the apps I have so not sure how else to deal with it, it's clearly an issue with other people reporting the same thing.

I'm having this exact same issue, Mail just quit on me for no reason. Lots of different apps are doing it, definitely a Big Sur issue.
