macOS Mach-O format resources?

[DeathChill]

I was trying to find information about the Mach-O format that wasn't related to OS X. Every reference to Mach-O is talking about OS X's use of it and since OS X uses some of its own conventions with sections and segments and all that I was wondering if anyone knew of any sites with information about the Mach-O format not related to OS X.

OS X seems to be the last (only) operating system that uses Mach-O. [Wikipedia]

If you can be more specific about what information you are looking for I may have some relevant documentation I could send you from back in my Mach kernel hacking days.
