Apple/macOS removed from official Unix registry

nsagent

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.

Better for both sides. They clearly have different visions for what an OS should do.

If true, a better title would be "macOS is no longer UNIX certified".

Well Unix as a standard is completely dead. macOS as a Unix is completely dead. I expect another branch in the already complicated as hell tree of Unixes.

It could be that macOS 27 never got Unix certified. Wayback Machine on Oct 7th only shows macOS 26 being Unix certified. https://web.archive.org/web/20261007103902/https://www.openg...

I could see this being corporate incompetence or a genuine deviation. I wonder which one it is.

I never quite understood what the point of this was beyond marketing. Linux is also not listed probably because no one ever paid to have it listed

And does this have any actual impact on either the OS itself or its users?

If this is an intentional move, Apple is just acknowledging reality. UNIX(tm) is no longer so relevant compared to the early days of OS X, when Linux was still in its infancy and the Unix certification gave Apple street cred among developers. Most developers these days target Linux for production. That's why Microsoft developed WSL, not WSU.

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.

The certification was always a bit odd, applying only to a configuration nobody would run in practice: https://www.osnews.com/story/141633/apples-macos-unix-certif...

Xnu’s Not Unix!

I won't be surprised if you will have to boot into recovery, disable SIP, come back to user-space and run those unsafe 'ls' and 'cat' commands you were trying to live dangerously with on '~/Library', and then go back to recovery again to renable SIP to stay safe . You may also have to do that to install every software you want to install and use on your (is it?) mac other than the ones that are from companies that had tied up with and signed Apple's USA certificaiton (i.e User Safety Alliance™; involving non-publicly disclosed deals), or from the smaller devs who were not small enough and could pay a few thousand dollars annually and sent Apple 3 kidneys annually to publish softwares with very reduced scope and access on the device/OS. The data transfer between your mac and those app endpoints will be so protected that even your own self-destructive hands and insufficient intellect won't be able to gather what is happening beneath the Apple's hardware hardcoded encryption. All for safety beyond the UNIX way. So not all surprising.

They used to marketing Mac OS X around Unix, but not anymore.

Solaris as well, apparently

It saddens me to think of all the CPU cycles spent on hosting online discussions that mention the fact that MacOS officially licenses the UNIX brand.

unix registry silently removed from relevance. linux compatibility is way more relevant now.

throw0101a

"Silently removed" meaning Apple probably did not bother going for certification of macOS 27. And I'm not sure why it would be non-silently/loudly removed: is there an expectation of a press release or weblog post about non-certification?

pjmlp

It is still there. For those that don't know how to use a filter drop down, check UNIX 03 version.
