Mac OS X is really not hardly anything at all like FreeBSD. The Apple marketing is talking about "the experience" or something and not the technical issues. Unfortunately this has caused quite a bit of confusion on the net and some of the brightest people are being duped into thinking that Mac OS X is actually based on FreeBSD. Many of the userland utilities are brought over from FreeBSD but I assure you the kernel, which is mostly Mach based with BSD stuff thrown in for filesystem and process management. [which of course needs to be glued to the Mach primitives to work]. All pthreads in Mac OS X end up being mach_threads at the lowest level, all BSD processes are mach_tasks. This is nothing like FreeBSD. It's also probably why you do not see tons of cross pollination of FreeBSD taking things from the Darwin XNU kernel. Once you start poking around on Mac OS X's Open Source bits you can see it's quite different.
