Specifically, it is based in part on BSD 4.4 Lite. On a system
level, many of the design decisions are made to align with
BSD-style UNIX systems. Most libraries and utilities are from
FreeBSD (http://www.freebsd.org/), but some are derived from
NetBSD (http://www.netbsd.org/). For future development, Mac OS X
has adopted FreeBSD as a reference code base for BSD technology.
Work is ongoing to more closely synchronize all BSD tools and
libraries with the FreeBSD-stable branch..
Your statements applied to the original OSX. It has shifted to 4.4BSD,
Mach 3, and FBSD during the course of development, with lots of
contributions from Net and OpenBSD. The changes didn't happen in the
last few weeks. They happened continuously during the system's
