The instructions for MacO X Mail are very similar. However, I believe that AOL no longer supports IMAP even though it still works in a fashion. I can receive, but not send AOL mail via MacOS X Mail. My guess is that the system was overwhelmed by SPAM. At any rate, you might consider using AOL's AOL Communicator as an alternative to Mail. It fully supports POP3 and IMAP in addition to full support of AOL mail. I don't use it, but it is the best option for unifying your AOL mail with your other accounts.
