here's what an actual OS X/Darwin machine has to say about itself.

Darwin purple 1.4.1 Darwin Kernel Version 1.4.1: Sun Sep 30 
20:54:21 PDT 2001; root:xnu-201.roots/xnu-201.obj/RELEASE_PPC 
Power Macintosh powerpc

dmesg stuff:

Copyright (c) 1982, 1986, 1989, 1991, 1993
         The Regents of the University of California.  All rights 
reserved.

and the console prompt says "Darwin/BSD" if that helps.

The only possible interpretation of any research whatever in the
`social sciences' is: some do, some don't.
