I cannot send messages on my iMac15,1, and cannot sign out of iCloud to try and fix it.
Hello.
I have tried updating to Big Sur on a couple of occasions, but as I've had issues doing so I've had to restore backups.
After doing this a few times, I've started having this issue where I cannot send messages from my computer. I hear the sound to say I sent it, but I don't get a delivered indicator. I have tried restoring again, but no luck. I've also tried signing out of iMessage and back in, still no luck. I'd like to sign out and back in from iCloud, but even that won't work. Upon me clicking to keep a copy of my content, it just redirects me to the iCloud page of my Apple ID preferences, without signing me out of anything.
Could I possibly have some help with this? It's starting, sadly, to get rather annoying.
