Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

Has your iMessage app ever worked before this? if so, for how long?

Is there any error code or error number in the error message given from iMessage?

And, does iMessage close at that point, or does it merely fail to log in ?

Customer: replied 9 months ago.

Hi there - yes the iMessage used to work perfectly - than just stopped.

There is no number / code.

Expert:  Russell H. replied 9 months ago.

Thanks for the screen-shot you posted.

And that error comes up when you try to sign in, correct? signing in, to iMessage?

Is your iMessage program on an Apple computer, I presume? if so, what changes/updates happened on that computer lately?

And, what is the current MAC OS X version on the computer that iMessage is on, please?

Customer: replied 9 months ago.
