I don’t know how I missed Apple saying that they have submitted Leopard for UNIX certification and branding.
OS Foundations
The heart of Mac OS X, the Open Source Mach- and BSD-based UNIX layer known as Darwin, continues to see improvements in Leopard. The latest Mac hardware brings more processing power, more cores, and more memory than ever before. The kernel in Leopard has been updated to take advantage of this new hardware.
Leopard certainly won’t be UNIX in name only. Apple will submit Leopard and Leopard Server to The Open Group for certification against the UNIX ‘03 product standard.
FWIW, any os that cares to take the time and effort to pass the certification suite of tests and of course pay for the certification testing by The Open Group can become UNIX branded.
There’s only a few players that meet the latest certification process.
Interestingly enough, right now that’s just Solaris on various platforms, and AIX 5L. Nobody else from the old UNIX wars is left standing on firm enough ground to try for the UNIX 03 branding. Not even HP, who’s HP/UX was branded at the previous level (UNIX98).
Most interesting.
I wonder why Apple is bothering. Perhaps they are going to make a stronger push into big business, aka Enterprise. Hmmm.
