Pixar Animation Studios, Apple CEO Steve Jobs' "other company", is relying more and more on Mac OS X, according to Pixar's "problem solver" Dr Micheal Johnson. As Jobs is Pixar's CEO, the Mac faithful often criticized the company's reliance on powerful Unix and Linux-based workstations, as well as Windows PCs, to coordinate the creation of its animated motion pictures. However, according to Apple's Web site, this has changed. Dr Johnson led a lunchtime session at last week's Apple Worldwide Developers Conference (WWDC) in the US. Johnson was there to talk about the increasing role of Mac OS X systems at Pixar, whose past credits include Monsters Inc, Toy Story and Toy Story 2, and A Bug's Life. Linux, Sun and Windows-based systems are being replaced by Mac OS X, according to Apple. "The studio's entire team uses Mac OS X not only for creative work, but for workflow and custom application development," the company claims. "We are looking to OS X for the future," Johnson says. He relays his own efforts to use Mac OS X's Cocoa development environment to create a custom software tool to animate the storyboarding process. "The first evening, I basically made it work," says Johnson. Within a week, it was complete enough to begin using on a new animated film project. "I could not have done this in Linux, not to mention Windows. This is the kind of thing that gets us excited," Johnson claims.
