The PC versus Mac debate has now become a full fledged war, on Team Fortress 2. Valve Software has announced that Team Fortress 2 is now playable on the Mac starting today and is free to play until June 13th. Mac users and PC users will be able to face off against each other in 2Fort, Badlands, and other great Team Fortress 2 maps. However, Mac users who log in before the free weekend is up will get one thing the PC users will never see, earbuds to put on any of the classes in the game. So get out there and fight for your side, Red versus Blue and Mac versus PC!
