It means nothing, it’s just a paycheck you sign and then you get to say “I certify my OS is Unix”. The little bit more technical part is POSIX compliance but modern OSs are such massive and complex beasts today that those compliances are tiny parts and very slowly but very surely becoming irrelevant over time.
Apple made OSX Unix certified because it was cheap and it got them off the hook from a lawsuit. That’s it.
Yup. It is all about paying the price, Microsoft could technically get Windows certified as UNIX. IBM did just that with its mainframe OS. Here’s a list of certified UNIX systems: https://www.opengroup.org/openbrand/register/
Microsoft could technically get Windows certified as UNIX.
I don’t think they could now that the POSIX subsystem and Windows Services for UNIX are both gone. Don’t you need at least some level of POSIX compliance (at least the parts where POSIX and Unix standards overlap) to get Unix certified?
But OS X, macOS, and at least one Linux distro are/were UNIX certified.
