Yesterday, we weren't sure if the list of Mac games in the Steam for Mac beta client were going to be available - not to mention functional! - for today's launch, but it appears our skepticism was misplaced. With the Steam for Mac service now live [DMG download] we were heartened to find that the list of 50 games, which you can read after the break, were still there and, even better, able to be downloaded! In this writer's case, games I had purchased on Steam for Windows previously (hello, The Dig!) downloaded just fine for me on Mac OS.

Like we said yesterday, many of Valve's other games, including the Half-Life and Left 4 Dead series, while still promised for the Mac platform are currently unavailable. We expect them to arrive in the subsequent weeks, as "additional collections of Mac titles will become available, each designed to highlight specific functionalities of Steam on the Mac." For now, you'll have to settle for Portal and Team Fortress 2 ... or one of the other 48 titles available today. We've bolded some of our picks after the break.

First, a word of warning to would-be Mac gamers: You don't need to download every game right away. They're not going anywhere! Just take it easy, one game at a time, and soon enough playing "games" on your Mac will feel just right as rain.
