With Steam for Mac set to debut tomorrow, we’ve got a little last minute information for you, thanks to the press release. The good news will come in the form of Steam Play, which allows users to purchase a game once and play it on all Steam supported platforms, ensuring that you won’t have to purchase the game multiple times. One of the more noticeable games that will be available on Wednesday will be Runic Games’ critically acclaimed Torchlight. Finally, Valve will be making its Steamworks suite of publishing and development tools available on the Mac platform. Features include product key authentication, copy protection, auto-updating, social networking, anti-cheat technology and more. Are you looking forward to getting Steam on your Mac?
