Unix vs Mac OS X, Notable Difference

Regarding an explanation of the explanation:See the FreeBSD forum. Basically the OS X userspace is essentially FreeBSD (with small elements of NetBSD) but the kernel itself is a fork of the MACH Kernel that makes it more monolithic in nature (like the network stack and process model are in line with FreeBSD). For a technical description, you'll probably have more luck googling Darwin than OS X since the latter has a lot of noise in it from people uninvolved with the project.
