I have tried even deleting and re-adding my account to no avail. MEssages will not connect with my Apple ID, period. The other accounts (AIM, GTalk, etc.) work fine. It seems to be a mac + Messages isolated issue and not related to my Apple ID (as both my iPhone and iPad are working fine with it) or the iCloud as a whole since all the other services (Calendar, Notes, etc.) are working/syncing just fine. This is what I get when I try to make it go "active"/login: Ideas?
