huh, isn't there a mac version of gaim?
edit: can't see one, but you could get the source package and compile it on your OSX machine for X.
http://gaim.sourceforge.net/it will handle your msn and your aim and a lot of other protocols with no intervention from microsoft and their thrustworthy computing.
edit: and anyway why are we talking about macintosh versions in the windows section?
