Steam and Source for Mac arrive in April, Valve confirms

Valve has made its support for the Mac official. Starting with the releases of Left 4 Dead 1 & 2, Team Fortress 2, Counter-Strike, Portal, and the Half-Life series, both Steam and the Source engine will be fully compatible with Macs starting next month.

In addition, Valve is introducing a new feature, called Steam Play, “which allows customers who purchase the product for the Mac or Windows to play on the other platform free of charge,” explains Jason Holtman, Director of Business Development at Valve. “For example, Steam Play, in combination with the Steam Cloud, allows a gamer playing on their work PC to go home and pick up playing the same game at the same point on their home Mac.” Valve expects most developers and publishers to take advantage of this.

According to Director of Steam Development John Cook, Valve is treating the Mac as “a tier-1 platform” and will be releasing all of their future titles, including Portal 2, simultaneously on Windows, Mac, and the Xbox 360.

“Furthermore, Mac and Windows players will be part of the same multiplayer universe, sharing servers, lobbies, and so forth.”
