Don't 100% accurate. The Darwin kernel comes with a BSD licence and can be considered free. Also a lot of tools are the usual suspects: Apache, Postfix, Perl, etc. All free (as in speech). The GUI part is proprietary though.
Last I knew the Darwin base was _not_ under the BSD license, but was relicensed from the BSD license to Apple's APSL license (which is considerably more restrictive).
