Seriously though, I tried putting FreeBSD on my Linux laptop a few years ago and it was not a fun time. Reminded me a lot of running Linux on desktop in the 2000s when I first discovered Linux.
I'm rooting for them though. I like the idea of keeping development and documentation so tightly integrated and maintained by a single dedicated company.
MacOS is actually not a BSD as some people like to think.
It is Unix, it used to be posix tested but it has never, ever been a BSD.
MacOS is based on the mach kernel, a kernel that was intended to replace the BSD kernel for a GPL licensed Unix. Most of the people who wanted a GPL Unix just went with Linux in the end. We are still waiting to see what Hurd has to off though.

Your point is well taken and I appreciate expanding my knowledge on this a bit, but I don't think that it is that cut and dry. Mach, the kernel from which both is not Unix. Mach is basis for XNU (X is not Unix, sound familiar). From the screenshots from Wikipedia, pretending that BSD is not embedded within MacOS is just trying to obfuscate things. The Mach virtual memory manager for instance is in FreeBSD, so it goes the other way around as well.
