The core of OS X is highly BSD-based and was released independently as
Darwin. Apple ceased releasing complete sources to Darwin when they
switched to x86.

For an example, when you boot OS X in single user mode (at least in the
past, I don't know about x86), the first message you see is the
copyright "The Regents of the University of California" stuff.
