You heard wrong, Mac OS X is not running a FreeBSD kernel.
well, not to say your wrongs or anything, but your wrong and so was I. It uses A BSD kernel and a MACH kernel (remember, it's kernel is BASED of these, not using the exact one)
It is not a BSD kernel. It is based on MACH 3.0. It is a BSD userland (with some gnu), like I said.
and I quote from the Mac OSX website...
"Beneath the easy-to-use interface and rich graphics of Mac OS X is <a href="/macosx/features/darwin/">Darwin</a>, an open source UNIX-based foundation built on technologies such as <STRONG>FreeBSD</strong>, <STRONG>Mach</strong>, <a href="/macosx/features/websharing/">Apache</a>, and GCC. Darwin provides a complete UNIX environment, with <a href="/macosx/features/x11/">X11</a> and POSIX services comparable to Linux or FreeBSD, including familiar kernel, libraries, networking and command-line utilities."
So if you take this to mean that FreeBSD and MACH both make up the kernel (beyond the typical code sharing in open source (if we want to include that we can say that Linux is a mix of Linux and FreeBSD technologies), then Apache and GCC are somehow parts of the kernel?
if you care to know it's at the bottom of <a class=ftalternatingbarlinklarge href="

The most widely-distributed UNIX-based operating system, Mac OS X offers a unique combination of technical elements to the discerning geek, such as the fine-grained multithreading of the Mach 3.0 kernel, tight hardware integration and SMP-safe drivers, as well as zero configuration networking. Panther integrates features from state-of-the-art FreeBSD 5 into Darwin, the Open Source base of Mac OS X, to provide enhanced performance, compatibility and usability.
p.s. If I am comming of like a jerk, I'm not trying to. Just a little friendly debate
Less of a jerk than I was. I can diggit.

BSD Component Version 5.5:
Mac OS X 10.1.5. Not the latest and greatest, but I doubt they did a complete kernel switch. Remember that Mac OS X is not a new OS really, it is built on NeXT technologies too. NeXT didn't run on FreeBSD's kernel, I think it was an earlier MACH
(not positive about the kernel origins odd NeXT, I haven't gotten a working NeXT machine yet
)
I don't have a FreeBSD machine, but I'll substitute OpenBSD instead (FreeBSDers or Mac OS X 10.3.xers can prove me wrong, or right by posting):
