Valve launched a new Beta of its Steam platform for Windows PCs on Tuesday, bringing with it a range of funky new UI changes. Generating the most attention however, are hints that the Left 4 Dead developer could be adding Mac OS X support to the client.The move from Microsoft's Internet Explorer and the adoption of a Webkit-based rendering engine had already raised suspicions. But
hawk-eyed Steam forum members believe they have found substantial evidence of Apple support, after digging into the source code.
Images for Mac OS X window functions – such as the Zoom, Minimise and Close buttons – sit alongside images named “steam_cloudsync_osx.tga”, an icon for the operating system's dock and menu files.
It is believed that Valve is making a more concerted effort to support Macs, due to the latest Source engine apparently supporting the Apple hardware.
Postal III will be using the Valve-created engine for release on Windows, Linux and Mac as well as the Xbox 360 and PlayStation 3.
