An analysis reveals that Apple's macOS UNIX certification is misleading, as macOS 15.0 only conforms to the outdated SUS version 3 from 2004, not the latest SUS version 4 required for the UNIX V7 trademark. The article argues that the certification holds little practical meaning despite Apple's long-standing tradition of obtaining it. This highlights the gap between marketing claims and technical compliance in operating system certifications.
Background
The Open Group manages the UNIX trademark and Single UNIX Specification (SUS), with certification requiring compliance with specific SUS versions. Apple has historically certified macOS releases as UNIX-compliant.
