Livecode server UNIX version (not Linux).

Not very sure, but months ago I read this (but he seems to talk about 
BSD user utils more than the Kernel).

Yes, Apple’s macOS can be considered to be a BSD UNIX.

    1) Apple’s macOS is an officially certified UNIX, that takes care of 
the UNIX part of the question.

    2) NeXT was created by using BSD OS, the Mach microkernel and then 
modifying those with new modules created by NeXT.

    3) Today's macOS is descended from NeXT (which Apple acquired and 
transitioned macOS to in 1999)

    4) Apple replaced the NeXT user interface with the world famous 
Macintosh user interface

    5) Apple, slowly over the years removed the NeXT modules and 
replaced them with pure BSD modules and some Apple custom modules

    6) The Mach microkernel was replaced with the Appel XNU hybrid kernel

    7) As of macOS Catalina 10.15, there is no longer any NeXT modules 
in macOS, macOS is now mostly BSD with a few custom Apple modules and of 
course the Macintosh user interface, which has been polished over the years

    8) So yes, macOS is BSD and at the same time it still is Apple Macintosh

    9) If you go to the command line you will see that it is almost 
completely BSD with a few Apple commands for security, file system, etc.

    10) If you are using it normally, then what you see is a pure 
Macintosh user experience.
