So what is a derivative of AT&T UNIX? Is it the codebase that makes it a derivative? BSD was rewritten to remove almost all AT&T code so that only a small fraction of one percent of the files had any AT&T (actually USL) copyright as of 14 years ago. On top of that, OS X doesn't even use the BSD kernel, but Mach. It contains the BSD userland and many utilities, but remember, BSD started as Berkely-written utilities for AT&T UNIX.
There is barely any, if any, codebase lineage to AT&T from OS X, yet somehow we refer to it as UNIX.
And if you sell your "Unix" without it being certified UNIX then you may be sued for trademark infringement even if it is an AT&T derivative. The people who own the name consider "UNIX" to be conforming to the standards, nothing to do with lineage. Or don't you believe they have the right to enforce their trademark?
I’d recommend just keeping quiet on the matter to you finally figure it out, should that day ever come.
No thanks. I'll stay and keep injecting facts into your fantasies.
Anything that was derived from or resulted from that code, duh.
BSD was rewritten to remove almost all AT&T code
So what? It's still a derivative.
OS X doesn't even use the BSD kernel, but Mach. It contains the BSD userland
Clearly making it a derivative. OSX is certified UNIX now too.

Sure they do, but BSD was "Unix" before they even existed, and trademarking the name isn't going to stop it from being generally referenced as such. No different than if Linus Torvalds suddenly decided he was going to revoke Novell's rights to use the Linux trademark, SuSE woud still be generally considered part of the Linux family, since that is/was its development base and remains it's technical bloodline. Simple to most, you'll no doubt still be confused though.
