• AIX
  
• "AIX (Advanced Interactive eXecutive) is the name given to a series of proprietary operating systems sold by IBM for several of its computer system platforms, based on UNIX System V with 4.3BSD-compatible command and programming interface extensions."
  
• HP-UX
  
• "HP-UX 11i (Hewlett Packard UniX) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on System V"
  
• Mac OS X
  
• "Mac OS X is based on the Mach kernel and is derived from the Berkeley Software Distribution (BSD)"
  
• OSF/1
  
• "OSF's standard Unix implementation was known as OSF/1 and was first released in 1992.^[2] For the most part, it was a failure; by the time OSF stopped development of OSF/1 in 1994, the only vendor using OSF/1 was Digital, which rebranded it Digital UNIX (later known as Tru64 UNIX after Digital's acquisition by Compaq)."
• Solaris
  
• "On September 4, 1991, Sun announced that it would replace its existing BSD-derived Unix, SunOS 4, with one based on SVR4."
  
• Tru64 UNIX
  
• "Tru64 UNIX is based on the OSF/1 operating system. DEC's previous UNIX product was known as Ultrix and was based on BSD UNIX. It is unusual among common commercial UNIX implementations, as it is built on top of the Mach kernel developed at Carnegie Mellon University."
  
• UNIX
  
• "Unix (officially trademarked as UNIX, sometimes also written as Unix with small caps) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations."
