"An error occurred during activation. Try again"
When I try to log into my iMessage on my Macbook Pro, an error message pops up and reads, "Could not sign in. An error occurred during activation. Try again." This won't allow me to log into my iMessage, and it has been repeatedly popping up for about a week. Anybody know how to fix this issue?
