That family tree is wrong, right? 1. Unix was first, then BSD came from Unix... then Mach was built quite a bit later. 2. NextStep was then built by jobs after he was let go from apple by Mr. Soda man. 3. Jobs comes back to apple, brings NextStep- reads the tea leaves with OS7-9 and sets up NextStep as the successor with OSX. Apple branded NextStep becomes OSX. Is my chronology correct?

I think so. OSX was bought, NT was bought, Android was bought. Which big OS vendor build their own OS? Maybe Google with Fuchsia?

  NT wasn't bought.

    Maybe a shortcut of Dave Cutler plus what Wikipedia said "While creating Windows NT, Microsoft developers rewrote VMS in C. Although they added the Win32 API, NTFS file system, GUI, and backwards compatibility with DOS, OS/2, and Win16, DEC engineers almost immediately noticed the two operating systems' internal similarities; parts of VAX/VMS Internals and Data Structures, published by Digital Press, accurately describe Windows NT internals using VMS terms. Instead of a lawsuit, Microsoft agreed to pay DEC $65–100 million, help market VMS, train Digital personnel on Windows NT, and continue Windows NT support for DEC Alpha" Also https://www.itprotoday.com/compute-engines/windows-nt-and-vms-rest-story https://www.itprotoday.com/compute-engines/windows-nt-and-vm...

      Using VMS in the 80s at my university, it was a solid foundation for creating a proper OS that NT became.

    It's a charitable gloss. One can argue that it was bought since DEC accepted compensation in the form of a ‘strategic alliance’ rather than go to court.

  OS X was bought from a co-founder in exile to revive the hardware platform championed by said co-founder, so the situation is a fair bit more complicated than most acquisitions.

Excepting a minor detail - NextStep brought Jobs to Apple rather than vice versa. Gil Amelio chose NextStep rather than Apple's own Copeland as the successor to System 7, bought NeXT, and never knew what hit him.

I think your chronology is correct, yes. The family tree in the article is not a chronology, I think, so your chronology augments it with useful information.

I believe your chronology is correct, but I don't see how it differs from the (primarily hierarchal) family tree given in the article.

The family tree is slightly off, but it’s not completely chronological. A 40 year old man might still marry a 25 year old woman and have children with her and the tree would put them on the same line. Your chronology is correct though. I think it was an aesthetic choice to make the grandparents symmetrical, but the only relation the Macintosh has to any other prior system is the Lisa, you could say the Lisa was influenced by the Xerox Alto. The Macintosh Project was founded by Jef Raskin and his vision for the Macintosh was entirely different before Jobs essentially pushed him out. A lot of the Lisa influence comes via Bill Atkinson who designed both QuickDraw and the Lisa user interface and worked on both Lisa and Macintosh. The tree discounts both Copland and Rhapsody as well. While Copland never shipped, much of the tech developed for it did, and while Rhapsody never shipped, Mac OS X Server 1.0 did. The only relation the Apple II has to any of this is they’re computers.

  I read somewhere that nobody had ever identified a technical person who had worked on Rhapsody. Now that's vapourware.

    It was realized more or less in Mac OS X Server 1.0, which despite its name is more Rhapsody than Mac OS X, and enough people bought it to complain when Apple quickly moved ahead with Mac OS X as we know it and didn’t offer any kind of discount on Server 10.0. EDIT: Not the best quality, but here’s a demo I found on YouTube for those interested: https://youtu.be/HrHNub_vJtA https://youtu.be/HrHNub_vJtA Basically imagine NeXTSTEP/OPENSTEP, but with a Platinum skin, the window server is still a Display PostScript interpreter, there is a Classic Environment in the Blue Box, and instead of the Finder you have NeXTSTEP’s Workspace Manager and its still App Kit and Foundation Kit. Carbon isn’t a thing yet, or it’s in early development and hasn’t been announced yet. I don’t recall if the kernel had replaced Driver Kit with IO Kit yet though.
