NeXTSTEP

NeXTSTEP is an operating system developed by NeXT Inc. Some of it elements were borrowed to the modern macOS. It wasn't successful as the Macintoshes at the time.
NeXT Inc. was started by Steve Jobs in 1985, after when he left Apple. The OS was developed in 1985. The first preview was released in October 12, 1988. It is initially released in 1989. NeXTSTEP continues to be developed by NeXT Inc. until the Apple-NeXT merger in 1997. NeXTSTEP would become Rhapsody. Rhapsody would later become Mac OS X.
NeXTSTEP was forgotten by the OSM community. NeXTSTEP was so obscure, mostly no one heard of it.
