    Nice to know, I’ve always thought BSD is actually UNIX.

    The BSD variants are descendants of UNIX developed by the University of California at Berkeley, with UNIX source code from Bell Labs. However, the BSD code base has evolved since then, replacing all the AT&T code. Since the BSD variants are not certified as compliant with the Single UNIX Specification, they are referred to as “UNIX-like” rather than “UNIX”.

      UNIX™ is a trademark name (Think of e.g. IBM AIX, HP-UX, SunOS). Linux and BSD are Unix alike. I believe that Apple has made an effort to be entitled to call an OS of theirs UNIX, not sure whether it’s Darwin or something else.

        UNIX is trademarked by ‘The Open Group’, Unix is not. 🙃

        To make things more confusing, according to German Wikipedia, Unix is used for Unix-like OSes which are not officially UNIX-certified. 😵‍💫
