Apple canceled the unstable and unfinished Copland project in August 1996, which had already been presumptively renamed "Mac OS 8", again leaving only a System 7 legacy. Apple's own book "Mac OS 8 Revealed" (1996) had been the definitive final roadmap for Copland, naming the platform's competitors and allies, and yet its 336 pages contain no mention of Pink or Taligent. In late 1996, Apple was ever more desperately scrambling to find any operating system strategy whatsoever beyond System 7, even after having already planned its upcoming announcement of it to be made in December 1997. The company had failed to deliver even a functional developer preview of Copland in two years; and it discarded the successful A/UX and PowerOpen platforms in 1995, and the new AIX-based Apple Network Server of 1996-1997. To build the future Mac OS, the company seriously explored licensing other third party OSes such as Solaris, Windows NT, and TalOS.
