Mac version of Steam on the way?

Members of the Steam community, digging through the code of the recently-released new beta version of the client for the download service, have uncovered evidence of plans for Mac support.

A thread on the Steam forums spotted by Kotaku uncovered a bunch of tell-tale Mac OS X files in the code, like the open, maximise and minimise icons, system dock graphics and menu files.

Whilst Valve's download service is mostly populated with Windows-only PC games, Kotaku points out that several publishers on the service including EA, PopCap and id Software do offer Mac versions of some or all of their games. Many of the indie games available on Steam also have Mac versions available elsewhere.

Valve has yet to comment on whether it's officially bringing Steam to Apple computers.
