Whilst BSD isn’t linux per se, it still has a lasting legacy in the unix like space and notably has been used in game consoles like the PS4.
For you in your personal use case, have you tried a bsd distro? What was better compared to the average linux distro?
Apparently BSD is more modular with its jailing system and seems to have a lower resource usage.
I look at ones like NETBSD and FreeBSD and think, "what exactly do I get out of them that I wouldn’t with Linux say, Ubuntu or Void as an example?
What are your thoughts on BSD, you use FreeBSD before?
MacOS is actually not a BSD as some people like to think. It is Unix, it used to be posix tested but it has never, ever been a BSD. MacOS is based on the mach kernel, a kernel that was intended to replace the BSD kernel for a GPL licensed Unix. Most of the people who wanted a GPL Unix just went with Linux in the end. We are still waiting to see what Hurd has to off though. https://en.m.wikipedia.org/wiki/Mach_(kernel)
Your point is well taken and I appreciate expanding my knowledge on this a bit, but I don’t think that it is that cut and dry. Mach, the kernel from which both is not Unix. Mach is basis for XNU (X is not Unix, sound familiar). From the screenshots from Wikipedia, pretending that BSD is not embedded within MacOS is just trying to obfuscate things. The Mach virtual memory manager for instance is in FreeBSD, so it goes the other way around as well.
