No it isn't.
The Open Group which does the official UNIX certification would beg to differ:

<http://www.opengroup.org/homepage-items/c399.html>
It's a heavily modified Mach single-server kernel with a
partial BSD userland. And Apple contributes little or nothing back.
<http://www.apple.com/opensource/>
lists scores of open source components that form part of Mac OS X and
to which Apple contributes its enhancements.
The market reality is that many programmers work on projects that are,
at least in part, closed source. Open source licenses other than the
GPL allow these programmers to use and contribute to open source
projects.
