Valve's Steam gaming service rolls out Mac version, with free Portal!

Mac gaming comrades, the day is upon us! Valve's awesome Steam gaming service has arrived on OS X, allowing Mac game junkies to finally play titles like Portal without running Boot Camp or setting up a Windows partition. You can grab the Mac client from and start downloading games right away.

Steam's Mac library is kicking off with Valve's own Portal -- available for free until May 24th! -- Sid Meier's Civilization IV, and Runic Games' highly-acclaimed Torchlight. More titles will be added each week, including Team Fortress 2 and Left 4 Dead 2. Also, Portal 2 will launch simultaneously on the Mac and PC versions of Steam. Beyond that, the selection of upcoming games is only speculation at this point.
