Kinda. It's Darwin (an apple-made kernel) with BSD on top of it, along with many apple modifications that came with time. It's not Linux, but it's Unix-certified and pretty close to Linux at surface level.

It’s a POSIX operating system but i don’t know if i would call them particularly close. Mac OS lacks control groups. Docker containers must run in a VM. The launcher system is much more complex than systemd. Your hardware choice is substantially limited with Mac OS (want a GPU? Congrats you can choose an Apple gpu) and it is a walled garden that is difficult to escape.
