You might be wrong about "The Year of Linux on the Desktop"

> macOS, unlike Windows, is a Unix OS, which means that all the key benefits you will find in Unix-like Linux apply to it too.

macOS, as shipped, is not a UNIX OS. You must manually modify the system in extreme ways to comply with the bare minimum of 2004's UNIX certification. Quoting OSNews: https://www.osnews.com/story/141633/apples-macos-unix-certif...

  So, if you want your installation of macOS 15.0 to pass the UNIX® 03 certification test suites, you need to disable System Integrity Protection, enable the root account, enable core file generation, disable timeout coalescing, mount any APFS partitions with the strictatime option, format your APFS partitions case-sensitive (by default, APFS is case-insensitive, so you’ll need to reinstall), disable Spotlight, copy the binaries uucp, uuname, uustat, and uux from /usr/bin to /usr/local/bin and the binaries uucico and uuxqt from /usr/sbin to /usr/local/bin, set the setuid bit on all of these binaries, add /usr/local/bin to your PATH before /usr/bin and /usr/sbin, enable the uucp service, and handle the mystery issues listed in the four Temporary Waivers.
