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. OS X 10.11 El Capitan includes rootless security. It makes sure that System file permissions are automatically protected, and updated during Software Updates. 
The Repair Permissions function is no longer available and access to system files that we need to use in this guide may be locked. Fortunately, we have found workarounds for this version of OS X. Here we provide guides in Post 1 in support for Installing OS X El Capitan on your Unsupported Mac.
This first post is usually updated with recently summarized information, updates, and more solutions. For those who have 2006/2007 Mac Pros, you may be best suited to using.
The MCPF and macOSE projects are not affiliated with them. We will not contact them for you either, that's your responsibility. Some confrontation has occurred both publicly and privately in MacRumors, the site, and other forms of communications and we don't want anything to do with them and their Mac Models. Its simple, don't ask Mac Pro questions to people who don't have Mac Pros. Your post will be requested to be moved to their thread.
