A few months back, Apple announced that it would stop supporting .me and .mac AIM accounts on OS X 10.7.1 and earlier starting June 30th. The company has put this change into effect, but it appears that the service is discontinued all versions of OS X users, not just ones running older versions.
Apple’s support article, first posted in April, and later updated in June, says:
To ensure a secure and reliable experience, customers using a mac.com or me.com ID to login to the AIM service via iChat must upgrade their Mac to OS X version 10.7.2 or later by June 30, 2014 to continue using the AIM service.
The folks at AppAdvice report that they’re not able to log in to their AIM accounts on OS X Mavericks and OS X Yosemite. The service appears to be broken not just on the OS X Messages app, but even with third-party clients like Adium:
I was using an old .mac address for AIM. Messages on my Mac were sent and received through the third-party Adium application. On July 1, the service was no longer operational on either of my two Macs. Currently, my iMac has OS X Yosemite installed, while my MacBook Air has OS X Mavericks.
Apple says the change is because the company is upgrading the security and stability of the service behind the scenes. It hasn’t however commented on the disruption in service for all OS X versions, leaving them in the dark.
