Sure, but given the timeline, it’s unlikely the decision came about simply because he was influenced by “the Pixar guys”. I pointed out that the goal for the first NeXT computers was to be able to do wet lab simulations, and this was due to a conversation Jobs had with Paul Berg while Jobs was still at Apple. They met again after Jobs founded NeXT before drawing up the initial spec in September 1985. More likely the decision to use Mach/BSD was because Avie Tevanian was the project lead for the operating system. 4Sight also didn’t debut until IRIX 3.0 (1987, also when it picked up the IRIX name), prior to that they used mex which I traced back as far as 1985 and prior to that I’m not sure, but I don’t think they had a window manager and it seems unlikely they would prior to 1985.
