Apple's upcoming operating system, Mac OS X version 10.5 “Leopard” has qualified UNIX 03 certificate by The Open Group. This means Leopard is conforming to the SUSv3 and POSIX 1003.1 specifications for the C API, Shell Utilities, and Threads. There are UNIX pretenders, and there is the real thing. Apple is to be commended.

Besides Apple, only Sun, IBM and HP are officially certified.

Art Technica has a report, Mac OS X Leopard receives UNIX 03 certification.

Art Technica wrote:
It may all sound like semantics, but the certification is actually quite important for Apple and for the OS. The UNIX 03 certification means that Leopard conforms to the Single UNIX Specification Version 3 (SUS), a specification for how things like the shell, compiler, C APIs, and so on should work.
(...)
The fact that Apple can use the UNIX name more freely is cool, but the certification will have a far bigger impact on enterprise customers. Any software written for the SUS specification is easily portable to a UNIX 03 operating system, meaning that enterprise customers who need a "real" UNIX for their applications can now use Leopard servers if they so desire.


Mac OS X is not just UNIX-based or UNIX-like, it is a true UNIX operating system.
