OSOpinion has published a fascinating article that describes the journey from NeXT to Mac OS X.
The report looks at how Apple began the hunt for a new operating system in 1996, and its move to acquire NeXT, which also saw Apple founder, Steve Jobs, hired as a consultant.
Jobs, of course, eventually ousted then CEO Gil Amelio to regain the Apple throne and turn the company around.
The report is an interesting history lesson for new Mac users, and a valuable reprise for those who need a reminder of the events in Apple's OS past.
It also reveals that initial development of the OS was made on PCs, "the first developer's preview still only ran on PC's", the report explains.
