...by which is meant, "Some differences between macOS, a certified Unix™, and systemd/Linux". Which is fine and valuable! But macOS is the most common Unix™, so the title as written is... entertaining.

I mean, I guess it's at least true that it's "based on Unix" through its BSD lineage, but still an odd turn of phrase as, as you note, macOS has been an actual, registered, UNIX 03 system since 10.5.

Interesting post; not sure I agree with all of it, though.

For example, I would not say /Library is equivalent to /usr/lib. /Library has lots of things that are not libraries as in .a or .so (actually .dylib) files and that would be in various different subdirectories somewhere on Linux.

Also, it’s a bit deceptive to show how you need 10 commands to add a user before saying you can do it all at once with a tool that was introduced 6 years ago.

And I’ve never had to use -isysroot with GCC from MacPorts, though I can believe that it is necessary in some special cases.

I think the post articulates well the issues with Homebrew, though.

Particularly as the reference UNIX seems to be a Linux with systemd, which isn’t UNIX.

De facto or de jure? Linux isn't technically one, sure, but given that Linux is where the OS hot-shit is now (e.g. eBPF, although I think FreeBSD has the basics - no idea whether it got merged but I saw a student project) is it not fair to say it's where Unix would've been had things been different?
