A collection of tools to run newer OS versions on Macs that don't officially support them
All of these patchers support GPU acceleration!
NexPostFacto 10.7 - install OS X 10.7 Lion on Early 2006 Macs which have had their CPU upgraded to a Core 2 Duo
NexPostFacto 10.8 64-bit - install OS X 10.8 Mountain Lion in full 64-bit mode on Macs with ATI X1300/X1600/X1900 GPUs
NexPostFacto 10.8 32-bit - install OS X 10.8 Mountain Lion in 32-bit kernel mode on all unsupported Macs with a Core 2 Duo or Xeon. Many fewer bugs than MacPostFactor.
NexPostFacto 10.9 - install OS X 10.9 Mavericks with GPU acceleration on Macs with ATI X1300/X1600/X1900 GPUs
Why the name? An homage to XPostFacto, which did the same thing for OS X 10.0-10.4.
