Apple/macOS silently removed from official Unix registry

Apple and macOS have reportedly been dropped from the official Unix registry, according to recent reports. The Single UNIX Specification serves as the governing standard for systems that aspire to use the UNIX® trademark. Compliance with this specification is crucial for systems seeking to display the UNIX® trademark. The Open Group's UNIX standards are renowned for their stability, portability, and cost-effectiveness across a multitude of platforms, ranging from mobile devices to mainframes.

UNIX certification functions as a widely recognized and open industry standard, guaranteeing that products adhere to stringent criteria concerning portability, compatibility, and global interoperability.

This facilitates procurement processes through the specification of UNIX conformance and bolsters the perception of UNIX systems as consistently stable, flexible, and dependable operating systems.
