To my understanding, Kernel = no, userland = yes.

The MacOS X Kernel is a modified Mach kernel.  Much of the non-gui part of
OS X was borrowed from either FreeBSD or NetBSD according to who you ask.

I don't know about current versions (I'll check my MacBook tonight) but in
the first versions of OS X you could go to a bash prompt and go peeking in
/etc and find config files that still had Net and/or FreeBSD headers and
version dates.  I was in a basic OS class at that time and we did a section
on MacOS X and I got in (a very little) trouble for cheating because one
quiz question asked us to find some network config settings and while
everyone
else was looking through their GUI, I was pulling the info directly from the
config files.  The Prof. didn't even know you could get a command prompt on
MacOS X and thought I had installed something.  He probably would have been
right except that I didn't need to, it's built in.
