Not quite. MacOS is a certified UNIX system, but Android is Linux which is a UNIX derivative clone. At this point, in sheer numbers there are more Linux servers than there are UNIX ones.

Linux was built to be a UNIX clone by Linus Torvolds and a host of open-source developers, and has no direct links to UNIX, which was developed originally by AT&T. Linux is a fully open-source OS, while UNIX is a mix (BSD is partially open-source, but as far as I know none of the others are).

Edit: Okay, this isn't a debatable point. Only systems certified by The Open Group are UNIX. Others can be similar to UNIX, or clones of UNIX, but they are not UNIX. Linux has never been certified as UNIX, and even if they requested certification they would not pass the requirements because while Linux is very similar to UNIX, it doesn't meet the benchmark requirements. Downvoting me doesn't change reality.

To further drive your point home, Linux is technically just the kernel which is pretty useless by itself, because there's no built-in way to interact with it.

The standard set of tools for interacting with the Linux kernel are the GNU utilities.

GNU stands for "GNU is Not Unix."

Linux is UNIX based and uses POSIX, it’s essentially a. GUI extension ontop of UNIX. We wouldn’t have it without UNIX. *NIX machines perhaps is more accurate than UNIX, but that’s just semantics. At its core LINUX is UNIX on crack. Obviously it’s come leaps and bounds away from UNIX in this age but it’s built ontop of it.

It's really not though. It shares no actual code from proprietary UNIX, and UNIX is an actual certification which Linux doesn't have. If anything, calling Linux UNIX takes away from all the work that Linus and the others did; they didn't simply repackage UNIX code, they wrote it from scratch and did an amazing job.
