SUS is “Single Unix Specification” or “Single Unix System,” I can’t remember which (I think the former). It’s the name of the certification that MacOS actually has.
I do have to say, I didn’t realize that they were close enough as to be co-portable. That’s really interesting.
Well, I don’t know the details about portability, but there are a couple of pages in their documentation where they straight up say they keep the tools updated, and the APIs are the same except <a list of maybe ten low-level differences> (which differences are in such areas of which I have never heard even with some rudimentary understanding of what Unix syscalls look like and what some parts of a kernel are).
Yeah, those details are firmly in the “deep magic” realm for me. I suppose I could figure them out if I wanted to spend the time trying, but I’d rather just assume that Apple’s engineers know what they’re doing. (And know that it really doesn’t affect me either way if they don’t)
Lol, nice.
