Valve announced today it will bring Steam, Valve’s gaming service, and Source, Valve’s gaming engine, to the Mac.

Steam and Valve’s library of games including Left 4 Dead 2, Team Fortress 2, Counter-Strike, Portal, and the Half-Life series will be available in April 2010.

The importance of this news is that it will bring gaming to the Mac platform, something that Mac users have long awaited for years. Valve will have a major hold into the Mac market with this move, and will prompt other game makes to consider the Mac a solid gaming machine.

“As we transition from entertainment as a product to entertainment as a service, customers and developers need open, high-quality Internet clients,” said Gabe Newell, President of Valve. “The Mac is a great platform for entertainment services.”

“Our Steam partners, who are delivering over a thousand games to 25 million Steam clients, are very excited about adding support for the Mac,” said Jason Holtman, Director of Business Development at Valve. “Steamworks for the Mac supports all of the Steamworks APIs, and we have added 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. 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. We expect most developers and publishers to take advantage of Steam Play.”

“We looked at a variety of methods to get our games onto the Mac and in the end decided to go with native versions rather than emulation,” said John Cook, Director of Steam Development. “The inclusion of WebKit into Steam, and of OpenGL into Source gives us a lot of flexibility in how we move these technologies forward. We are treating the Mac as a tier-1 platform so all of our future games will release simultaneously on Windows, Mac, and the Xbox 360. Updates for the Mac will be available simultaneously with the Windows updates. Furthermore, Mac and Windows players will be part of the same multiplayer universe, sharing servers, lobbies, and so forth. We fully support a heterogeneous mix of servers and clients. The first Mac Steam client will be the new generation currently in beta testing on Windows.”

Portal 2 will be Valve’s first simultaneous release for Mac and Windows. “Checking in code produces a PC build and Mac build at the same time, automatically, so the two platforms are perfectly in lock-step,” said Josh Weier, Portal 2 Project Lead. “We’re always playing a native version on the Mac right alongside the PC. This makes it very easy for us and for anyone using Source to do game development for the Mac.”

Many Mac users have already started complaining about the “ribbon” menu feature of the suite, but at the same time praising that Microsoft is finally releasing a new version of the Office suite for the Mac.

Microsoft is investigating reported issues with Windows 7 and notebook battery life. The issue seems sporadic, but fairly widespread. It is unclear whether affected systems are simply misreporting the battery life, or if the battery capacity is actually being permanently affected.
