Don't mind me. Just copying a thread from an awesome developer, TMRJIJ. I didn't claim that I made this guide of the patch. Don't tell him if you contact him

Apple History
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. 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. 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.
Fortunately, we have found a work around for these version of OS X. Guides and support for Installing OS X Yosemite on your Unsupported Mac can be found at MacRumors web site.
