Over twenty years ago, a number of companies came together to acknowledge the value of the UNIX® platform, but more importantly, the need for all UNIX® implementations to be interoperable.
 

 

The Single UNIX Specification provides a level of openness which those without the standard cannot, ensuring compatibility across platforms.
Read the blog.

Focus is on open standards for operating systems, including the UNIX® system, POSIX®, open source operating systems such as Linux® and BSD, real-time systems and network computing. The Forum is also the specification authority for The Open Group UNIX certification program.  Find out who our members are.

Apple, Inc. has achieved UNIX® certification for its latest operating system – Mac OS X version 10.11 known as “El Capitan.” El Capitan was announced on September 29, 2015 following it being registered as conforming to The Open Group UNIX® 03 standard on the September 7, 2015.

The Open Group works closely with the community to further the development of standards conformant systems by evolving and maintaining the value of the UNIX standard. This includes making the standard freely available on the web, permitting reuse of the standard documentation in open source projects, providing test tools, and developing the POSIX and UNIX certification programmes.
