I bought a gamepad to use with Halo, and found after I got home with the game that Halo doesn't support a gamepad on the Mac. This stinks. Slightly less annoying: I bought a Dual 2GB G5 and a 23" Cinema display so I could do things like playing games in high-res, but Halo only supports up to 1280x960. I'm disappointed. This game would be a lot more fun if it were not crippled in these ways. I hate to say it, but due to these limitations, this game was a lot more fun on my buddy's XBox.
