NexPostFacto

A collection of tools to run newer OS versions on Macs that don't officially support them

As of 2021-12-23, NexPostFacto is no longer supported and will receive no further updates. It has become much less useful as the OS versions it supports age, and I no longer use it myself.
All of these patchers support GPU acceleration!
NexPostFacto 10.5 (ATI Rage GPUs) - enable hardware OpenGL acceleration, as well as DVD playback, on unsupported Macs with ATI Rage GPUs running OS X 10.5 Leopard; the first patch tool to provide graphics acceleration for unsupported GPUs on OS X 10.5
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 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; has many fewer issues than MLPostFactor and MacPostFactor
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; has many fewer issues than MLPostFactor and MacPostFactor
NexPostFacto 10.9 - install OS X 10.9 Mavericks with GPU acceleration on Macs with ATI X1300/X1600/X1900 GPUs; the first patch tool to provide graphics acceleration for unsupported GPUs on OS X 10.9
Why the name? An homage to XPostFacto, which did the same thing for OS X 10.0-10.4.
