Hi All,
I have a question on contacting Apple Support regarding the You cannot sign in to iMessage on this Mac at this time. Please contact Apple support.
I tried to contact them via the Apple web site and one of the first things they ask for is your serial number. Entering the generated serial number returns that it is invalid and then you are stuck. Has anyone called Apple lately with a non-valid serial number and what happened. I have read older posts where support tries to validate the number and then gives up and resets the account. Are you screwed contacting Apple without a valid serial number.
Also when trying to log into iMessage, it does not prompt for the validation number, I have 2 factor validation turned on. I am wondering if this might be part of the problem, though I did turn on 2 factor validation after I initially tried to log into iMessage.
As for my Apple ID and system settings they should be good. I have a credit card associated with my Apple ID and iMessage Debug shows the same values across reboots and the customer code generated is always the same.
Thanks for your help.
