You might find the below link interesting. Zoom in.

Thanks, dhs12345, it is quite interesting. As I said, Mac OS X, soon to be called AppleOS, is one of the few UNIX™ that is fully POSIX® certified UNIXes left.

i had no problem zooming in or downloading. The Macs use display PDF so it makes things much easier to handle PDFs. Again, thanks for that quite interesting overview of the UNIX development and family tree.

I was able to view it as a link but when I tried to download and view it, it lost its formatting. Might be a setting in acrobat — if printed out it would be several feet wide. Lol.

Anyway, it is clear that Linux and BSD diverged and are not directly compatible versions of Unix. As I read on the Internet, Linux and BSD are distant cousins; related but different. A lot of complaints about wifi drivers, etc. which is typical of Linux. Been there done that.

Also, Linux users tend to be tinkerers and roll your own types and Mac users don't care what is going on behind the GUI — just make it simple and easy to use.
