Steam for Mac launches tomorrow with Portal leading the line

Whoa, just got some more Steam for Mac details to share with y’all. It comes out tomorrow, as you well know, but did you know that Portal will be the first game available for the Mac platform? Well now you do!

Valve calls the ability to buy and play games on one platform (Mac or PC) then be able to play it on the other (PC or Mac) “Steam Play.” Of course, not ever game supports Steam Play, so this is a case-by-case basis.

Portal will be the first such game. That should mean that if you already own the Steam version of the game for the PC (like me!) then you’ll be able to play it on Steam for Mac, too. Neat.

Games will be released for Steam for Mac on a weekly basis. Also released tomorrow: Torchlight.
