Parts of it are. The kernel is derived from a Mach microkernel (an experimental kernel in the 80s, which was theoretically supposed to allow different OS personalities to coexist in the same system, sharing resources; macOS’ Darwin/XNU kernel doesn’t implement this capability in full, but you do get the Mach Ports interprocess communication mechanism, and a BSD UNIX personality permanently attached).
Yes, and the FreeBSD kernel is also derived from it, but they both formed out of that. One to form NeXT mach and the other Net, which forked to NetBSD and FreeBSD. But macOS Mach isn’t derived from the FreeBSD fork.
It’s also the only desktop OS that’s actually Unix. MacOS gets official Unix certification with every major release. All other “Unixy” OSes are just “Unix-like”.
Really? They might use some GNU programs, but I’m sure the default user land for OpenBSD is all theirs. Just because you know cp etc. as GNU utils doesn’t mean the BSDs use the same ones. They are just part of the operating system. https://github.com/dcantrell/bsdutils tried to collect various BSD implementations for example
The “coreutils” that macos uses by default are all older shitter bsd versions. I discovered this when half of my scripts and commands didnt work properly.
Silly me thought I could just bring my cash scripts over and not have any major issues (I’m not doing anything crazy). But even something as simple as grep didn’t work right because it could recursively search directories in the old bad version Mac comes with.
All of the gnu versions are much better and you can install them with homebrew.
People used to care a lot. The GNU utils absorbed everything all the old Unix vendors did. This made them comparatively heafty back when a high end workstations might have had 64MB of RAM.
Now that Chrome takes up gigabytes per tab, nobody cares except a few old Unix curmudgeons.
Shouldn’t it then be the Linux triplets? Linux, OpenBSD and macOS?
macOS is the bastard evil child given for adoption that no one in the family will ever acknowledge.
So Wario, then? Maybe that makes Android Waluigi.
I’d say it’s more like Toad. Overly simplified, weirdly smooth and shiny.
If macos is Wario, surely iOS is waluigi?
Also, macOS is derived from FreeBSD.
It’s derived from BSD 4.3, which predates and is one of the ancestors of FreeBSD

Meh. It’s a nice bragging right, but that’s all it is at this point. Linux killed off almost all the old Unix vendors for a reason.
They’re not Linux though?
BSD/openBSD ain’t either.
I’m sorry you feel that way about fish Linux
That’s the joke.
I know, it just seems like we’re moving in the opposite direction of correctness.
They can, and often do, use GNU tools and binaries underneath.
But do not run Linux, the kernel.

Yeah, I had a few scripts just act weird on osx. The parameters were different and some of them just behaved differently. It was oddly frustrating.

Wahhhhh this tool can’t do two things well, it should only be doing one thing well! 😭😭😭
GNU+XNU
Or as I’ve started to call it, GNU minus Linix
That’s the joke.
