Facebook messenger does not work on Macbook Air M1

Hey IJudeR,

We'd be happy to help point you in the best direction for support. With no details on how Facebook Messenger isn't working on your MacBook Air M1, it's difficult to say whats going on here from your initial post. If this is the app from the Mac App Store you're having issues with, try deleting it and reinstalling it. To delete, drag the app to your Trash and then redownload it using these steps: Redownload apps and games from Apple - Apple Support

If this is the function of their website you're having issues with or reinstalling the app doesn't help out, you'll want to contact their support team for support on this matter using this link: Messenger Help Center

We hope this helps out.

Take care!
