VALVE TO DELIVER STEAM & SOURCE ON MAC
 Leading Gaming Service Expands to Mac Platform
 March 8, 2010 - 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.
 "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.
