Nope. Used to be competitors. I thought Apple owned Pixar, originally, but it was actually Steve Jobs. I thought there was some relationship between Quicktime (Apple's old media software if you are old enough to remember) and the Luxo Jr. lamp character from Pixar's logo screen, but my Googles didn't turn anything up.
Another bit of trivia: so the worst-rated Disney animated movie of all time, there,
Wild, was actually directed by and made under the studio founded by Steve "Spaz" Williams, the legendary computer animator who leapt animal motion capture animation years ahead with his work on
Jurassic Park. He was acknowledged as the genius wunderkind who made the impossible possible even by the other nerd legends who were responsible for pulling off the special effects in that movie that dazzled the world. I still remember the first time I watched it in the theater and the scene came where you look out at the Brontosauruses in the valley. It's part of the magic of that movie. Because the way Sam Neill reacted as his character seeing live dinosaurs after a lifetime of digging them up perfectly encapsulated how we, the audience, felt looking at those computer models in the movie for the first time. We'd never seen anything like it. Their realism was breathtaking.
But I guess there's a difference between being that nerd genius who helps Spielberg enchant an audience with your tech wizardry, and being the wizard Spielberg himself.
