Valve's PC gaming platform and online store, Steam, is coming to Apple's Mac. And while it's not yet available to Joe Everyman, some people are already messing around with it, giving us our first look at it in action.

And, surprise! It looks just like it does on PC. Only, it's running on a Mac desktop, instead of a PC.

The settings and options all look as you'd expect, but the one thing we really want to see - the full list of games available at launch - isn't there. Bummer.

Oh, and some advice: hit mute before watching.
