Open Group
A standards organization responsible for UNIX trademark certification, which registers and renews systems that conform to the standards through the Open Brand certification program.
Timeline (last 90 days)
Apple failed to renew the UNIX certification that expired on August 29, and starting August 30, macOS is officially no longer a UNIX system by definition.
On the Open Group's UNIX certified products page, Apple's entry has disappeared, leaving only IBM, Hewlett-Packard and SCO Group systems listed, about nine products in total.
The Open Group's UNIX certification is a commercial model in which each product version is registered individually and renewed periodically; vendors must submit test suite results and pay a fee, and the certificate lists the specific product version and validity period.
Historically, Apple repeatedly renewed certificates for different macOS versions, and in 2018 negotiated with the Open Group to adjust testing requirements to accommodate macOS's differences.
FreeBSD, NetBSD and OpenBSD, systems directly descended from UNIX lineage, are not certified as UNIX by the Open Group.
Linux is a UNIX-like system, but it likewise has not obtained UNIX certification from the Open Group.
The POSIX standard and UNIX trademark certification are two separate systems: the former is a technical specification, the latter a commercial trademark license.
