Cannot login to imessage on Mac
Hello,
I got a new phone and my imessage was working fine until today my apple ID was signed out so I signed in no problem and am unable to sign into iMessage.
When prompted to sign in I put the correct Apple ID and password and no reaction, no message or anything. So I changed the password. Prompted again I login to with new password and imessage prompts: The user name or password was incorrect. Try again. Now both old nor new password work. When I put the old password "an error occurred during authentication appears in red.
Please advise.
Thank you,
