Tahoe was Unix 03 certified, and is still listed on that page if you filter by standard and choose Unix 03.

Perhaps Golden Gate simply hasn't yet passed certification.

I swear I've seen these "[Latest macOS release] does not appear in UNIX certification site" threads every year since the release of Big Sur in 2020.

It takes several months for the certification to appear on the site. What would be newsworthy is if we see a release next year without this release getting certification.

Apple originally certified Mac OS X as a UNIX because they used the word UNIX all over their website and the Open Group came knocking; they decided it was cheaper/better for goodwill to do the conformance and pay the license fee than to fight the case in court.

Looking now, I see almost no uses of the word UNIX on the website except the docs archive, so I guess they’ve decided to abandon both the certification and the use of the UNIX trademark in macOS.

		Maybe. But I don't remember seeing them use the word for the last decade, and the last-but-one release was certified. My first guess would be that it's too new, and hasn't passed certification yet.

Indeed. And, weirdly, there are items that show up by that 03 standard alongside macOS 26 (e.g. "HP-UX 11i V3 Release B.11.31") that also show on the front page. Is it a latest version kind of thing?

		Yea — said as much in another comment. That looks like it could be the rule — for example your HP-UX version there appears to be the latest, final HP-UX.

		Yep linked page is active certification rather than historical.
