Apple’s Operating System Chief Quits

Apple Computer Inc. said the head of its computer operating system division, Isaac Nassi, resigned from the company to pursue other interests. Nassi headed the Applesoft Division of the Cupertino, Calif.-based computer company for the last two years. Apple declined to elaborate on Nassi’s reason for leaving, including whether it was the result of disagreements over the company’s direction under Chairman and Chief Executive Gilbert Amelio. The company said Nassi’s duties will be assumed by Ellen Hancock, Apple’s new chief technology officer. Apple has been widely rumored to be interested in buying Be Inc., a start-up firm founded by former Apple executive Jean-Louis Gassee, a move that could allow Apple to improve its operating system. Apple’s stock lost 25 cents to close at $24.75 on Nasdaq.
