I got a chuckle out of that for my own reasons as a long time Mac user as “Mac OS X is Unix” was the brand back in the 10.0-10.3 days, to the point I believe they got a Unix certification by someone, and then again with macOS 15 they got an Open Group UNIX certification.

I can’t say this affects me in any way I’m aware of, but the perception presented here is interesting.

Funnily enough, they had no certification and weren’t compliant in 10.0-10.3 days, so what they were doing was trademark infringement, hence the lawsuit from the Open Group. 10.4 was the first compliant version. And oh boy they really milked it for several years afterwards.
