> They took a robust kernel, FreeBSD, and created a GUI and tools on top of that. I think they also essentially took over FreeBSD or at least forked it internally. They used NeXT’s XNU kernel which was a merger between CMU’s Mach and Berkeley’s 4.3BSD. They later refreshed it with code from OSF’s MK derivative of Mach (which also incorporated some code from the University of Utah) and code from FreeBSD, and have added a huge amount of new code of their own. They continue to pull new code from FreeBSD every now and again, but it isn’t so much a plain fork of FreeBSD as a merger between parts of FreeBSD and a lot of other stuff with a completely different heritage |
