I don't know hat version of UNIX OSX is based on in X.5.
But up to .5 it was first based on BSD licensed from Berkly University.
Then later and up to and including x.4.11 its based on FreeBSD.
with the advent of Intel Macs I'm wondering whether they switched Xfree
based Unix (UNIX type that is used on PC's)
but OSX is a three layer system.
the GUI what you see is Apple's Mac style interface Mac users are used
to the second lay is or was FreeBSD Unix what the Mac Finder actually
manipulates and then at the core it has what is called a Mach or Mock
kernel. This was a system create after Jobs left Apple and started a
another project using Motorola based o40 processors I've forgotten what
the machines were named but the had one of the most tough and stable
Operating systems ever know they surpassed even UNIX or Linux for
stability and reliability. Since steve Jobs own the right to that
technology he used that as the center core of OSX's three layer Technology.
And as for UNIX power in you go into single User mode or use the Console
you can use any FreeBSD UNIX command you want. You even have the ability
to destroy the System if you don't know what your doing. Just like in UNIX

This isn't Unix, it's OS X - which is Unix-*based*. The 3 A.M. cron-romp
went out circa 10.2 (IIRC). The maintenance scripts run on startup as
needed.
