It's also not surprising that the integrated Intel GPUs won't see official support - a beta tester noted that he was able to get Portal running on his MacBook with integrated Intel graphics, but the frame rate was only 10-15 FPS on the lowest settings.Ĭounter-Strike, 'The Half-Life Series,' Left 4 Dead, Left 4 Dead 2, Portal, Portal 2, and Team Fortress 2 have all been confirmed for release on OS X, with presumably more games on the way later on. Those still using PowerPC Macs may cry foul, but I imagine the work it would have taken to get Steam running properly on PowerPC would have been both difficult and expensive, with little payoff for Valve. Some of these details are not at all surprising, particularly the minimum requirements of having a 10.5 install and an Intel CPU.

Steam and Source will run natively in OS X - no emulation whatsoever One purchase will work on multiple platforms You will not be required to purchase separate versions of Windows and Mac games. Source games require 10.5.8 or 10.6.3 or higher, and are not supported on the X3100 or 900-series Intel chipsets (the integrated graphics chipsets in older MacBooks) Considering the first act ends with a cliffhanger and many questions to be asked, to see the second half explain almost none of it makes for a frustrating story. Forum sleuths at Steam's site have put together a list entitled ' What we think/know about Steam for Mac' that gives us some information about the forthcoming release of Steam for OS X. The second act of the game has an increasingly incoherent story that explains very little of what is going on. Details have emerged regarding Valve's release of its Steam games platform for the Mac.
