You mean NeXTSTEP, all that makes it unique isn't part of POSIX, and Steve Jobs had a quite clear position on UNIX value for desktop computing.

macOS is not a UNIX-based operating system. It used to be marketed as "UNIX" but only because it met the Open Group's POSIX standards.

Not only does macOS comply to the POSIX standard, it also is a fully certified UNIX system.
