semthex from Hackint0sh.org, in collaboration with AppleTVHacks.net has done it again! A complete replacement to the Mac OS X kernel has been built which allows the full version of Mac OS X to be run on an Apple TV.
Semthex wrote a processor emulation for the kernel, to sidestep the hardware restrictions that previously disallowed Mac OS X from running on the Apple TV. AppleTVHacks.net was only too happy to help out, and when it turned out we needed more testers we launched a competition to get some. Within hours we had hundreds of eager Apple TV hackers submit entries.
Several hours of testing and refining later and our tester, gimli, managed to follow the steps (included below) to get Mac OS X booting on his Apple TV (click to enlarge):
The Apple TV running Mac OS X can use the mouse and keyboard normally, and you can run regular OS X apps easily. You can use either Front Row or Back Row (or Joost, or VLC, orů) to watch content, and can use it for most things you would use a Mac for.
