Here we provide guides in Post 1 and 2 and support for Installing OS X Yosemite on your Unsupported Mac. When Apple dropped the 32-bit kernel entirely from OS X, starting with OS X 10.8 Mountain Lion, EFI32 Macs no longer had an Apple-supported mechanism to boot newer OS X versions.įortunately, we have found a work around for these version of OS X. However, Apple did not support booting the 64-bit kernel in Macs that shipped with EFI32 firmware, even if they had 64-bit processors capable of running the 64-bit kernel. OS X 10.6 Snow Leopard was the first OS X version with optional support for a 64-bit kernel, allowing booting either with a 32-bit or 64-bit kernel. Please do not hesitate to post if you have questions. This thread consists of members prominent in these patches that can help you solve your issues. Kexts are provided to help a little bit.OS X Extractor is somewhat for more advanced users and should only be used as an alternative to MacPostFactor.
Installing on these models may cause them to have graphical issues as stated in these pages. Please note that older GPU (GMA 950, X3100, X1600, X1300, X1900, 7300gt, etc.) Graphics Acceleration on Mavericks and Yosemite is not supported yet but this thread consists of many graphical workarounds.
MacPostFactor works for Mountain Lion, Mavericks, and Yosemite (certain Models). OS X Extracter and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks(10.9), or Mountain Lion (10.8) on your older Mac.
