User level: Level 1 (4 points)After installing Tahoe last month, iMessage requires me to log in regularly. However, the login doesn't work and it says "an unexpected error has occurred". I've tried changing my password, no help. I uninstalled iMessage and reinstalled and it worked for a day, then back to the same problem. What else can I do?

Re: "iMessage not working with new update"
If you haven't already:
You might want to try restarting your Mac (Apple menu > Restart) as that will often restore order if something is not working s expected.

Else: Wondering whether Apple Support's trouble-shooting articles (links below) can help:
See what to do: If you can’t turn on or sign in to iMessage or FaceTime on iPad, Mac, or Apple Vision Pro - Apple Support
and
If you can’t send or receive messages using Messages on Mac - Apple Support

If needed: Apple provides a Messages Support website:
(info. / support / contact options etc.)
Messages for iPhone, iPad, Apple Watch, and Mac - Official Apple Support
