MacOSX is closer to real Unix (BSD derived flavor IIRC, aka Darwin), not Linux....

Ahh UNIX - what is "real UNIX"? Many years ago I was employed to develop and port a virtual run time system and compiler (written in C) between various flavors of Unix. Nowadays UNIX is pretty ubiquitous, but back then (in the 80's) UNIX came in all shapes and sizes (both SYS-V and BSD). They were not particularly compatible at the processor/machine architecture level. And some were not even compatible at the system utilities level (i.e. lp, cron etc)
I ported the virtual run time to these systems: XENIX, HP-UX (PA-RISC 32bit and Itanium 64bit), DG/UX, DEC OSF1 (Alpha 64bit), AIX, Solaris, UniSys Unix and a few other ones I can't remember.
