For those that don't know how to use a filter drop down, check UNIX 03 version.
Developed WSL and discontinued SFU (Windows Services for UNIX), which they had since NT 4 days.
The original POSIX Subsystem (psxss.exe) was Cutler's team who implemented a minimal POSIX.1 subsystem server alongside Win32 and OS/2. This was done primarily to satisfy US Federal Government procurement requirements (FIPS 151-2).
In these efforts they also tried to create successor languages to C, Alef and Limbo (for userspace), and never cared that much about anything past C89.
He has settled with Linux because that is the winner of UNIX wars, which predated Linux wars on Distrowatch.
As for the original UNIX,

Perhaps Golden Gate simply hasn't yet passed certification.
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?
I just wonder if macOS will stop being UNIX like.
That is, whilst it still has home brew and a BSD core it’s great. If that goes away it’s no longer a viable alternative to Linux.
It’s insanely common.
Given that Windows made WSL in an attempt to capture developer mindshare, that tends to support his comment
The remaining differences are related more to systems stuff - managing daemons with launchd for example. These aren't really a distraction day-to-day.
Developers and operations people are already starting to move to Linux. More and more I see colleague either switching to Linux, or have a mac laptop for administrative tasks and then a Linux workstation, or VMs, where they do their actual work.
I’ve been in this industry for a long time now. Linux always had more credibility among devs and ops folk. This “starting to move” view is weird.
My view is that OS X was acceptable by these teams because it was close enough to Linux and corporate could deal with it.
When I worked in corporate IT Linux was simply not an option for a primary workstation because there was no standard configuration or management tooling that made everyone happy. Macs were an easy compromise.
Neither Apple nor NeXT had a UNIX culture, and efforts like A/UX and mkLinux were never that much serious.
Had they acquired Be, BeOS was even less UNIXy than NeXTSTEP.
Edit: love how I get downvoted for facts?! They literally broke Cocoa so it was throwing hopeless useless exceptions at the bottom of the stack when they changed the native file open boxes to run in another process. Two bits of software I use couldn't raise an open file dialog window any more.
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.
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.
Perhaps Golden Gate simply hasn't passed certification yet? It's less than a month old.

It was Stallman who came up with the name POSIX by the way.
linux compatibility is way more relevant now.
