Also known as OPENSTEP

NeXTSTEP is a discontinued object-oriented, multitasking operating system based on the Mach kernel and the UNIX-derived BSD. It was developed by NeXT, founded by Steve Jobs, in the late 1980s and early 1990s and was initially used for its range of proprietary workstation computers such as the NeXT Computer. It was later ported to several other computer architectures and was later bought by Apple Inc. to replace the older Classic Mac OS with macOS.
