Mac OS X uses their own kernel and userspace, but with some system software from FreeBSD. To FreeBSD they've contributed (still copying from unverified source) to the USB stack, SMP code that removed the giant kernel lock, filesystem journaling came from darwin, superpages, dtrace support, ARM support, support for more than 16TB of ram, pure 64 bit support.
