Mac OS X is bsd.
Apple retains two versions of Mac OS X, both the server and the client.
The server is based on NextSTEP.
The client is based on Mach.
However it should be noted that both use the Darwin subsystem and have
become such hacks together that the client and the server are rarely
The Mach Kernel is based off of bsd 4.2.
Then the Mach Kernel progressed into Mac OS X (developer release 1).
This then progressed into the base of Darwin 1.0
The beta test program was then merged into Darwin.
Then OS X 10.1 of the Mach Kernel line merged into Darwin's current
Where as NeXTStep came from 4.3BSD and Mach. It then became OpenStep,
then it became Rhapsody. Rhapsody then branched out into two different
products, Max OS X Server 1.0 and Darwin 0.1. The Mach Kernel version
began to filter into this as well and this Mac OS X server version
continues to gain from its Darwin core.
>From here Darwin is still being developed and has been ported to intel,
but aqua has not.
