> A decent chunk of the kernel was directly lifted from FreeBSD
Sure, just as we already discussed at the very beginning of our exchange. Glad you able to learn something from our discussion, even if it has taken you an astoundingly long to time to get there. Here I was starting to think you were one of those who reject learning. I am happy to learn that you're just slow.
I've learned you are rude and presumptive. I was previously aware of the provenance of macOS's kernel.
