Both Linux and macOS are UNIX{,-like}. Implementation may differ between the two, but they share the same core interfaces and concepts. macOS, though, is far more user-friendly. I mean how many people would even look at macOS compared to Linux, a BSD, or something like AIX and guess they share very similar internals?

Of course, this isn't to say that those internals necessarily need to be as locked-away as those on macOS, but it is possible to hide them away and have a system far easier for the average person.
