I use 3 different Macs for work - MacBook, MacBook Pro, and an 24" iMac. I recently moved and never bothered to unpack my PC gaming machine...which is over 4 years old now and really lacking compared to my work computers.
I'd be interested to see how many other people out there run AH2 on a Mac and what problems (if any) you've run into.
I have AH installed on a 24" iMac, runs under Leopard/Bootcamp/WinXP..only problems I HAD was with a bogus sound file, (removed same) and the Clipboard spin. After I installed the following Hotfix : "Windows XP Hotfix Patch: KB896256 " issue with the Clipboard disappeared.
