After downloading the Mac player, all of the service's games will be available to you, with the exception of the "Windows" games (duh). By going to the "search games" area and clicking the "playable on Mac" box on the right side, you'll see a list of titles available for Macs specifically. Although a significant portion of the GameTap catalog gets lost here (including marquee games like Sam & Max), it seems Mac owners will have to take what they can get. The Apple core here at Joystiq is just excited to be in on the gaming smorgasbord.
