Steam for Mac has launched and with it comes dozens of games for the Mac. Valve has even made Portal free for Mac and PC until May 24.

Surprisingly, I’ve never played Portal before. But, I did manage to have a little bit of time with it today on my iMac. Needless to say, it’s a great game, anyone with an Intel Mac that has anything higher than Intel integrated graphics should head over and grab it, it’s worth your time.
