Editing NeXTSTEP (section)

==History==
NeXTSTEP was built upon Mach and BSD, initially [[4.3BSD-Tahoe]]. A preview release of NeXTSTEP (version 0.8) was shown with the launch of the [[NeXT Computer]] on October 12, 1988. The first full release, NeXTSTEP 1.0, shipped on September 18, 1989.<ref name="osxbook">{{cite web|last=Singh|first=Amit|title=What is Mac OS X?|url=http://osxbook.com/book/bonus/ancient/whatismacosx/history.html|work=osxbook.com|access-date=April 18, 2011|date=December 2003|archive-date=May 14, 2012|archive-url=https://web.archive.org/web/20120514135706/http://osxbook.com/book/bonus/ancient/whatismacosx/history.html|url-status=dead}}</ref> It was updated to [[4.3BSD-Reno]] in NeXTSTEP 3.0. The last version, 3.3, was released in early 1995, for the [[Motorola]] [[68000 family]] based NeXT computers, [[Intel]] [[x86]], [[Sun Microsystems|Sun]] [[SPARC]], and [[HP PA-RISC]]-based systems.

NeXT separated the underlying operating system from the application frameworks, producing [[OpenStep]]. OpenStep and its applications can run on multiple underlying operating systems, including OPENSTEP, [[Windows NT]], and [[Solaris (operating system)|Solaris]]. In 1997, it was updated to [[4.4BSD]] while assimilated into Apple's development of [[Rhapsody (operating system)|Rhapsody]] for x86 and PowerPC. NeXTSTEP's direct descendant is Apple's [[macOS]], which then yielded [[iPhone OS 1]], [[iOS]], [[iPadOS]], [[watchOS]], and [[tvOS]].
