Jobs started the company called NeXT focus on computer develop. NeXT started work on its computer in early 1986, after Apple dropped its lawsuit. Steve aimed at the highest possible standards for his new machine: he wanted the best hardware, built in the world’s most automated factory, and running the most advanced software possible. He decided the computer’s operating system, NeXTSTEP, would be based on UNIX, the most robust and most complex system in the world — but that it would also be as easy to use as a Macintosh, thanks to its own graphical user interface. However great it was, the NeXT Cube didn’t sell. By 1993, NeXT had to give up its hardware business and focus only on promoting its advanced software technology.
NeXT Software, far from beating Apple, had turned into a niche software development business. Steve was devastated, until 1996, Apple acquired NeXT company. The MacOS X system which we are so familiar with nowadays was just developed basic on NeXT's works.
