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".

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 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.

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

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.

Wahhhhh this tool can't do two things well, it should only be doing one thing well! 😭😭😭

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.

I for one prefer demon linux over fish linux. In fact, that's how I first dipped my toes into the world of unix-ish OSes with FreeBSD 3.3.

I always figured BSD should lean into the daemon imagery with a full heavy-metal branding: a suite of wallpapers with decidedly less cuddly daemons, a succubus OS-tan character... make it the go-to Edgelord Desktop.

Then FreeBSD introduced that stupid sphere logo. No sense of branding. :P
