Xinuos is an American software company that was created in 2011 and creates and sells operating system software. It was first called UnXis until assuming its current name in 2013. Its headquarters are in Berkeley, California.[1]


UnXis was formed when the operating assets of The SCO Group, which had been in bankruptcy for several years, were acquired in a public auction in April 2011 by Stephen L. Norris and a Middle East private equity group for the price of $600,000.[2] In particular, the company took over the product names, ownership, and maintenance of The SCO Group's flagship operating system products, OpenServer and UnixWare.[3][4]

The SCO Group's litigation rights against IBM and Novell did not transfer to UnXis, and The SCO Group subsequently renamed itself to The TSG Group.[2][4] UnXis, and later Xinuos, indicated in 2011, and again in 2013, that it has no involvement in any ongoing aspects of that litigation.[3][5]

Initially, UnXis was headquartered in Nevada and its CEO was Richard Bolandz.[2] In June 2013, it changed its name to Xinuos.[6] By then its President was Sean Snyder.[6] The company has facilities in California, Europe and Asia.

In June 2015, Xinuos announced OpenServer 10, which is based on the FreeBSD operating system. Simultaneously, Xinuos introduced a migration path for existing customers using older OS products. In December 2015, Xinuos released "definitive" versions of OpenServer 5, OpenServer 6, and UnixWare 7, which are upwardly compatible with newly released Definitive 2018 versions.[7][8][9]

In December 2017, Xinuos released "Definitive 2018" versions of OpenServer 6[10] and UnixWare 7[11]. In October 2018, Xinuos released "Definitive 2018" version of OpenServer 5. [12]


The main products of Xinuos are the following:

  • OpenServer 10 is an x86-64 operating system based on FreeBSD, which was announced in June 2015,[13][14] and released in January 2016.[15]
  • OpenServer 6 Definitive 2018 is an IA-32 Unix operating system based on the SVR5 kernel in an environment to maintain compatibility with OpenServer 5.
  • OpenServer 5 Definitive 2018 is an IA-32 Unix operating system which was originally developed by the Santa Cruz Operation. OpenServer 5 was a descendant of SCO UNIX, which is in turn a descendant of Xenix (SVR3.2).
  • UnixWare 7 Definitive 2018 is an IA-32 Unix operating system descending from AT&T UNIX System V. UnixWare 2.x and below were direct descendants of SVR4.2, and was originally developed by Unix System Laboratories (USL), Univel, Novell, and later the Santa Cruz Operation. UnixWare 7 was sold as a Unix OS combining UnixWare 2 and OpenServer 5 and was based on SVR5. UnixWare 7.1.2 was branded OpenUNIX 8, but later releases returned to the UnixWare 7.1.x name and version numbering
