Q: Late '11 Macbook Pro iMessage won't sign in
As of 2 days ago, iMessage on my Late 2011 Macbook Pro running 10.11.6 won't sign in. I keep getting "An error occurred during activation. Tray again." message. I have signed out of both my iPad and iPhone and messed with making sure the time zone is correct. I have messed around with deleting a couple of supposedly related .plist files that I found in suggestions here on the boards.
My iMessage still remains to work just fine on my iPhone and iPad. I was using iMessage fine on my mac until I noticed my responses to messages were only going out as SMS and not as iMessage. But the responses back from the other person came in as iMessage. I tried signing out thinking that might help and now I can't sign back in. I am getting very frustrated with this. This is also affecting FaceTime on my Mac, I get the same error message but FaceTime still works fine on my iPhone and iPad.
OS X El Capitan (10.11.6)
