NEW YORK - July 18, 2001 - Quark Inc. today announced that QuarkXPress, the industry-leading page layout software, will be built natively for Mac OS X. Quark executives previewed the carbonized version of QuarkXPress, dubbed version 5.x, as part of Apple's keynote address today at Macworld Expo in the Jacob K. Javits Convention Center in New York. "Quark stands strongly behind Mac OS X and we're working diligently to make QuarkXPress run natively on Apple's next generation operating system," said Juergen Kurz, Quark's vice president of product management. "Since a significant number of Quark customers are also Apple customers, Mac OS X is an integral part of Quark's future." "Featuring unprecedented power, speed, and graphics capabilities, Mac OS X provides tremendous business opportunities for developers that need a robust and flexible platform to create software," said Ron Okamoto, Apple's vice president of Worldwide Developer Relations. "The migration of Quark's flagship QuarkXPress page layout software to Mac OS X offers Mac users another great application for our state-of-the-art platform." A pre-release version of QuarkXPress 5.0 that runs in the Classic environment for Mac OS X is currently being tested by hundreds of businesses with demanding print and Web design workflows. Quark will apply the same rigorous standards to the version of QuarkXPress that will be native to Mac OS X.
