Gaming?  On a mac?  The words Mac and Gaming used to be mutually exclusive.  Today things have changed with the official launch of Steam for the Mac.  The best part?  Just for downloading Steam (on a Mac at least), you get a free, awesome game, Portal! Yessiree, Valve is giving you a copy of Portal just for getting on Steam!  All you have to do is get the Steam client, signup if you still don’t have an account and download the game.

The best part, you’ll be able to play your copy of Portal on your Mac or on your PC (just not simultaneously :)).  Just look for the Steamplay logo to see if the game you want is available for both versions of Steam.

Personally, I’d recommend that you get Portal, Torchlight and Civ IV!

If you think Portal is the only game coming to the Mac then you’re wrong, there’s a total of 63 games currently listed as FOR MAC on the Steam Store.

Putting off your download of Portal?  Don’t wait for too long since it’ll only be free until the 24th.  After that you have to pay for the game in full (or in a sale if you’re lucky).  What?  Portal is only free to play until the 24th? Is the question that probably popped into your mind right now.  Portal is free for life so long as you download it on a Mac on or before the 24th of May.  After that period, it’s no longer free.  Get it?  Good, now download it now.

As for the Linux version?  Sit tight guys.  It’s coming and soon.
