	This has been mentioned quite a few times on this list.
	The kernel is a Mach kernel, conceptualized by a professor and
his research group out at Carnegie Melon some years back (I want to say
7-8 years), and the userland for the OSX operating system is FreeBSD based.
	Hunting around Wikipedia a bit will most likely facilitate any
answers you may have about Mach (and micro) kernels, OSX, and FreeBSD.
