Steam for Mac is 100 percent official. Valve just released a statement saying it plans to launch it this April. The first games available will be Left 4 Dead 2, Team Fortress 2, Half-Life (and expansions), Counter Strike, and Portal. Portal 2 will be the first game released for Mac and PC simultaneously. Pretty big news, yes.
Steam will be fully native on the Mac, that is, not some rubbish emulation—it uses WebKit (“Safari”). That makes me jealous: Steam for PC uses Internet Explorer, and it gar-bage. It’s the worst part about Steam.
Valve bigwig Gabe Newell said, “As we transition from entertainment as a product to entertainment as a service, customers and developers need open, high-quality Internet clients. The Mac is a great platform for entertainment services.”
Welcome to Steam, Mac users! I look forward to sniping you all in Team Fortress 2 over and over again until you accuse me of using an aiming bot, the quit in a big huff. Mwahaahaa~!
