I see macOS 26 listed under the Unix 03 standard. Was macOS 27 listed and then removed? The submission title + site contents combined do not give enough info to assess what exactly was silently removed.

macOS was listed on the main register (the link in this submission).

It was Tahoe, it’s since been removed.

The UNIX03 page still lists it, but I believe that’s a mistake.

macOS has been removed from the main register/list.

The index page seems to only list the status of current OS versions.

Perhaps Golden Gate simply hasn't passed certification yet? It's less than a month old.

macOS Tahoe was certified on launch (September 14th 2025)

		Yes, that is interesting and certainly lends credence to the OP’s interpretation.

The this is much ado about nothing. Every single entry on the page you linked goes to its product page with the exact Unix standard it is certified as. Once you select a filter, you cannot get back to unfiltered list without the back button on the browser.

This is just a site rendering issue. Rather than silently removed, it's more like some bug was introduced. macOS 26 is still Unix 03 certified.
