If you believe the posters in one forum thread, Valve's content delivery service Steam could soon be making its way to Apple's Mac platform. But rather than the typical rumours from a friend of a friend who knows somebody that works for the company, graphics and files specifically referencing Mac OS X have been discovered in the current PC version. A file known as C: Program FilesSteam
esourcemenusosx.menu contains definitions for OS X menus, as well as a form of platform checking in the file SteamPublicsteamui_english.txt with the line:
"steam_welcomeaction_platformwrong" "%gamename% is not available on your current platform."
