Cannot log in to iMessage on Macbook Air
I am trying to log in to iMessage on my MacBook Air however the following error message (screenshot attached) appears. I have troubleshooted the following:
- Changed network and tried to connect via 2 alternate internet sources via Hotspot.
- Followed the steps at this URL: https://www.saintlad.com/error-occurred-during-activation-for-imessage-or-facetime-on-mac/
I can log in to iCloud on this device, however iMessage and Facetime (from everything I've read they seem to be linked) refuse to log in.
MacBook Air 13", OS X 10.11
