Introduction
This project is a new and updated branch of the Yosemite tree and is targetted at OS X 10.11 El Capitan with SIP support, automatic installer detection and fake board-id injection for unsupported models of the MacPro and MacBook Pro.
Os X El Capitan Update
- Personally, I did it on my Mac Pro ’08 (MacPro3,1), which officially supports only OS X 10.11 „El Capitan“. With the „macOS High Sierra Patcher“ I managed to install the latest macOS (10.13).
- The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion or has a Mac preloaded with OS X Mavericks, Yosemite, El Capitan, or macOS Sierra. Download the Application from the Mac App Store using your Apple ID on any Mac or functional computer running OS X 10.7.5 or later.
Download
All downloads of boot.efi should be done from this project page. All other sources are unsupported.
Jul 18, 2016 This update is recommended for all OS X El Capitan users. The OS X El Capitan v10.11.6 Update improves the stability, compatibility, and security of your Mac, and is recommended for all users. This update: Resolves an issue that may prevent settings from being saved in accounts with parental controls enabled. Download Mac OS X El Capitan 10.11.6 for all Mac users. This is latest version DMG image iso file OS X El Capitan 10.11.6 (bootable) for Mac users. Again in the left side of TransMac, right click on your USB drive and this time select “Restore with Disk Image” and then select the copy of the “EL Pwn Version.dmg” file you should have.
Download your copy of the prebuild (32-bit) version of boot.efi for El Capitan (compiled on Microsoft Windows 10 with Microsoft Visual Studio 2015) with a black background and white Apple logo now, and verify the download by entering (either one) in a terminal window:
Or download the one for legacy hardware, with a grey background and logo for your Mac Pro and verify the download by entering (either one) in a terminal window:
Note: If the output is different, then your copy of boot.efi should not be used!
Compilation
Don't want a prebuilt copy of boot.efi then compile the source code yourself, with either Microsoft Visual Studio 2013 or 2015. The latter requires you to update the solution files, but that should be done automatically in the MS Visual Studio IDE.

Thanks To
This project would not have been possible without the help of Peter Holbrook, Mike Boss and a number of other people. Peter did all compiling and Mike ran dozens of test builds that Peter pushed out over at forums.macrumors.com Awesome work guys. Job well done!
I'd also like to thank everyone else whoh helped with testing our nightly builds. Thank you so much!
Help
Os X Yosemite
If you need help with the setup then please visit this macrumor thread. Developers, or people who need help with compiling boot.efi themself, can visit this macrumors developer thread.
Note: I myself don't own any unsupported Apple hardware with a 32-bit EFI implementation, so I can probably do not much for you, but there may be others to help you.

Dosdude1 El Capitan
This article is about macOS High Sierra – but the newer versions are working the same way.
There is a way to install newer versions of macOS on older unsupported Macs. The tool is called „macOS High Sierra Patcher“ and can be found on this website with instructions:
Personally, I did it on my Mac Pro ’08 (MacPro3,1), which officially supports only OS X 10.11 „El Capitan“. With the „macOS High Sierra Patcher“ I managed to install the latest macOS (10.13). Now I have Siri and many other new features on this computer. The usage is still very good.
