AFAIK, Mac OS X is quite Unix-like, being based on
Darwin, which is Mach, BSD, etc.
It has chmod, chown and all.

:
"Mac OS X and the Power of UNIX
Beneath the appealing, easy-to-use interface of Mac OS X, you'll find an 
industrial-strength, UNIX-based foundation called Darwin. This open 
source core of Mac OS X is highly stable and built on mature technology:

     * A Mach 3.0 kernel with support for symmetric multiprocessing.
     * Based on 4.4BSD with networking from FreeBSD 3.2.
     * Support for most POSIX APIs.
     * Popular UNIX development tools such as gcc, gdb, vi, emacs, pico,
        Perl, etc.
     * Popular UNIX shell tools such as grep, chmod, ps, crontab, top,
        tail, etc."
