TRY TO LOGIN TO IMAC WITH APPLE ID AND IT JUST FLASHES
I have an imac18. Yesterday everything was working fine but then I updated to macOS Monterey and now I can't login to ANYTHING. Try to login to imessage, facetime, anything and it says unknown error. Tried going into the keychain and deleting the auth token but it asks for my keychain password. I type it in and it flashes and says its wrong. Reset my computer login, shut down computer and did the option+command+p+r until the second chime. relogged in tried everything again and it still wont do it. even when i try to go into my keychain and restore to defaults it asks for a password. This update literally screwed everything up and I've tried everything online and can't fix it. AND I would just erase the whole system but I don't even have erase all contents under my system preferences. ANYONE able to help??
