AOL Instant Messenger (AIM) users should use a current version of AIM software for compatibility with iChat users who are using a .Mac account name.
Symptom
Online users of iChat and AIM cannot communicate.
Solution
Affected AIM users should update to a later version of AIM software.
Visit the AIM Web site to download new software (http://www.aim.com/).
Note: Third-party AIM clients may not work as expected. For best results, both parties should use either AIM or iChat.
