Here is a quote from this (http://news.com.com/2010-1071-1015624.html?tag=nl) CNET news article:
Apparently, Apple's Mac OS X is not UNIX certified.
This looks really bad for Apple and Mac OS X.
The quote is from The Open Group. The Open Group owns the trademarks related to UNIX. They have a program to certify systems for UNIX compliance.At this time we do have a legal case of our own against Apple Computer. Apple has been using the Unix trademark on and in connection with its OS X product. This constitutes an infringement of our trademark since OS X is not certified under our Unix system certification program, and Apple has refused to use that program to obtain certification. Apple is obviously a valued member of The Open Group, and we have tried to reach an arbitrated settlement. However, all of our offers have been declined, so we have had no choice but to fulfill our duty to our customers and the industry as a whole to protect the Unix trademark.
