In a lengthy interview with Slashdot, Kottke and Fernandez discuss various scenes in the movie and reveal what really happened. Fernandez hasn't seen the movie because he considers it a work of fiction and it would likely upset him to watch it.
V.A: There’s also the big dramatic scene where Woz quits Apple.
Daniel Kottke: Yeah. That never happened at all. At all. That was complete fabrication.
V.A.: Really? His lines there are some of the most poignant phrases in the movie.
Daniel Kottke: Yes, it is poignant, and so I think it makes sense in the film, even though it never happened. So, I don’t know, the reality was that Woz was welcomed and encouraged to be part of the Macintosh project, but then he had his plane crash and so he was out of commission.
V.A.: Which I don’t think is even mentioned in the film, is it?
Daniel Kottke: No, it’s not. Bill Atkinson put it very well—he said Woz’s sense of humor is completely missing. Which is a big part of his life.
Bill Fernandez: That would be really bad if that were true, because a big part of Woz’s personality is his sense of humor.
