So you can't boot OS X by taking stock Darwin/XNU and recompile? If so that is kind of disappointing. I understand they have private code that they don't want to open up but it would be nice if you could still boot with a self-compiled kernel.
Glad to hear. It was suspect. "I can't be bothered to figure out how to build so I guess we'll patch the binary."
I guess Apple doesn't exactly shout from the rooftops how to do this but I see now that this is the top Google hit for "building xnu". So it's not too hidden.
