WSL is such a pain compared to just using a unix os from the get, which is of course what macos is. People forget that it is in fact a unix distro.
So no. The MacOS you use is not Unix.
It's just that mishmash of OSFMK (with BSD APIs of 1991 or so) with random additions of newer APIs does not necessarily make it a great Unix to work with in 2026

As for tmux, I know UNIX since 1993, went through Xenix, DG/UX, Solaris, NeXTSTEP before GNU/Linux started to take off, worked across Solaris, HP-UX, Aix, OS/X before GNU/Linux really took off.
To this day I don't care tmux exists, just open a couple of terminal windows.
If you are going to mention jobs across sessions, nohup does the job.
They buy macOS and then complain macOS isn't Linux, duh!
