"XNU's Mach component is based on Mach 3.0, although it's not used as a microkernel. The BSD subsystem is part of the kernel and so are various other subsystems that are typically implemented as user-space servers in microkernel systems."
"XNU's BSD component uses FreeBSD as the primary reference codebase (although some code might be traced to other BSDs)."
