iMessage on Mac stopped working, but FaceTime still works
I'm seeking some help on what I can do to get iMessage to work on my Macbook Pro again. They stopped syncing with my computer about a month ago and I get errors when trying to send messages from my computer (everything is working fine on my phone). I've gone through the checklists of fixes that usually work to solve this issue (restarting iPhone/Mac, software updates, force quitting messages, signing out/signing in, ensuring text message forwarding is on, etc), but nothing seems to help. I also noticed that FaceTime from my Mac is still working fine, so the problem is limited to iMessages on my computer. Thanks!
MacBook Pro with Retina display, iOS 11.2.6
