Oh no! a lot of text. Well, luckly half of the post is troubleshooting. EFI development setup is easy :)

Okay, before starting this guide you should have some tools installed already.

Mac OS X. For this guide I run version 10.12.5 (16F73)
Xcode 8. For this guide I run version 8.3.2 (8E2002)
Homebrew. A package manager for Mac OS X. https://brew.sh

First of all visit https://opensource.apple.com/release/developer-tools-821.html

You need to download the cctools package. This package contains various tools to deal with Mach-O files, which is the default binary file format used by the XNU kernel. It is an equivalent to the GNU binutils package on the GNU OS. (directlink)

Introduction to XNU compiling

From version to version, I always love to play around with the kernel. And it has always been a great lack in guides and documentation on how to build Mac OSX’s kernel, XNU. For those of you that already have tried compiling XNU for Mac OSX 10.12 (Sierra), you probably noticed that earlier build guides like ssen’s blog - Building xnu for OS X 10.11 El Capitan don’t work anymore. However, many thanks to ssen to put in time to write a guide.
