I think that it is more clearly expressed as MacOS X has a BSD interface to the Mach VM.
Mach has always had this sort of relationship with BSD and it still exists.

I looked, and it too says next to nothing about
Unix (which it describes as a
"programming language" - pg. 346). Oh well.
Pretty funny, or sad, depending on your viewpoint!
This is really a pretty serious omission, given
that the vast majority of
mobile devices now run Android, which is a Unix derivative (Linux). So just
about everyone has a Unix-derived thing in their pocket.
To hear some people talk, everything started with Linux, and Torvalds
is a god. Nonsense.
Even iOS and MacOS are derived from BSD, I believe. I know that MacOS
is (or has been until relatively recently, at any rate) derived from
BSD.
MacOS X is derived from BSD + Mach VM, with lots of infusions from BSD and other
projects. iOS is derived from MacOS.
