Quark has announced that QuarkXPress 7 will be the first major publishing application to run natively on both Power PC and Intel-based Macs.

A beta Universal Binary version that supports both processor architectures will be available by the end of January and the production version will ship later this year.

Beta versions of QuarkXPress 7 for Power PC-based Macs and Windows are now available for public beta testing. The software is available for free download from the company.

"The availability of this software shows that we're serious about delivering on our commitment to become a more open and customer-focused company," said Jürgen Kurz, senior vice president of desktop products.  "With Universal Binary support in QuarkXPress 7, cutting edge creative teams will be able to work together on the most up to date Apple hardware to make the creative process faster and even simpler."

"We're thrilled that Quark is one of the first major Mac developers to deliver a beta Universal Binary version of its software," said Ron Okamoto, Apple's vice president of Worldwide Developer Relations.
