MacOS didn't go so far as =E2=80=A2removing=E2=80=A2 their legacy = backwards compatibility with legacy Unix antiquity. But so much of MacOS i= s Unix-esque reinterpretation. MacOS still has the ghost of Unix-past anti= quity, but not of the ghost of Unix/Linux present, and likely not the ghost= of Linux future (because even Linux is charting an overtly divergent cours= e from Unix (e.g., systemd)). Take for example launchd in https://developer.apple.com/library/archive/doc= umentation/MacOSX/Conceptual/BPSystemStartup/Chapters/DesigningDaemons.html= #//apple_ref/doc/uid/10000172i-SW4-BBCBHBFB=20 launchd daemon is unique to MacOS: https://en.wikipedia.org/wiki/Launchd Note that launchd is Unix-esque in its general look & feel, but launchd is = not any of {systemd, cron, init scripts} that are accepted in Unix/Linux ca= nnon. Another 1 of the 4 categories is XPC. XPC again is very Unix-esque but has= no direct equivalent in any other flavor of Unix or Linux, because XPC is = bolted deeply onto Grand Central Dispatch (which again is vaguely Unixy* bu= t unique to MacOS and iOS). * Had Grand Central Dispatch appeared in BSD-world or SystemV-world during = the 1980s or early 1990s, it would be part of the Unix-world cannon, but it= didn't so it isn't.
