In my last post about MacOSX gaming, I mentioned I like to play Counter Strike / Left 4 Dead, and how I attempted to run it via Parallels virtually etc etc etc. Well, yesterday, Valve announced some AWESOME news for us Mac owners… I can’t wait to try this out 
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.
