Apple has issued an update for its Mac OS X operating system. The update addresses issues related to reliability for built-in applications and services, and more. It’s available for download through the Software Update system preference pane. According to Apple, Address Book, Classic compatibility, the Finder, FireWire, graphics, OpenGL, and Sherlock all feature improved functionality and reliability under this release. AFP and Windows file-service improvements have been made, and audio, disc recording, graphics, and printing improvements feature. Apple currently has approximately 5,000 native Mac OS X applications available for the reported five million Mac OS X users that have switched to the next-generation operating system. Apple CEO Steve Jobs said during last month’s Macworld Expo keynote address that the company is hoping for nine to ten million users by the end of 2003. Several applications have been recently released specifically for Mac OS X, including iLife, Keynote, Final Cut Express, and the company’s newest Web browser, Safari.
