I think you are making a unsubstantiated claim. Linux may be more popular than Unix, but I definitely would not call it superior. I believe it gets it's popularity because it has a lot of developers and thus supports more hardware. Apple makes their own hardware, so they have no reason to use a kernel that supports lots of hardware that they are not going to sell. I think they made the correct choice in using BSD Unix over Linux - they get a very stable kernel and don't have to deal with Linus's ego.Linux is far more popular and superior than unix
OS X itself has much more (exclusive) features than an Unix-like OS or a 100% Unix certified OS needs and I don't think that strict Unix conformity is a must. But depending on who you ask you will get different opinions about this.There's a reason why systemd is more powerful than other init systems:
we don't limit ourselves to POSIX, we actually want to give the
user/administrator the power that Linux can offer you.
Neither does OS X.Actually UNIX is an OS. And Linux is UNIX-like, but does not use any UNIX source code.
There is no "BSD UNIX" in OS X. It is based on the opensource BSDs.I think they made the correct choice in using BSD Unix over Linux
It's not "built from UNIX". It incorporates code from the opensource BSDs (which are NOT UNIX).Linux and Unix are very similar and Iam aware that OSX is built from Unix
See this thread for a recent discussion: https://forums.macrumors.com/threads/1681424/Linux and Unix are very similar and Iam aware that OSX is built from Unix
but my question is that if Linux is far more popular and superior than unix, then why couldnt Apple built OSX from linux instead of Unix?
