In June 2005 at Apple’s Worldwide Developers conference, Apple announced its transition from the PowerPC to the Intel x86 architecture. As part of its plan to ease the migration to the new platform, Apple unveiled its Rosetta technology. This technology ensures full functionality of software applications compiled for the PowerPC ™ architecture running on the Intel-based Macs.

> News on QuickTransit® and Rosetta.

In January 2006 at Apple’s MacWorld, Apple announced the immediate availability of their first Intel-based computers and their intention to have all their computer offerings transitioned to Intel processors by the end of 2006. The new Intel-based computers will all be deployed with Rosetta as a standard component, enabling users to run most applications that were compiled for the Mac OSX/PowerPC on their Mac OSX/Intel computers. The transition to Intel-based computers has gone extraordinarily well thanks in large part to the effectiveness of the Rosetta technology. According to Apple:

"Most existing applications will run on your Intel-based iMac, too. Simply launch them as always. Thanks to Rosetta technology in Mac OS X, they look and feel just like they did before.”

"Rosetta dynamically translates most of your PC-based applications to work with your Intel-based Mac. There’s no emulation. No second, class status. It looks and feels just like it did before.”

"Mac OS X Tiger includes an innovative software translation technology called Rosetta that lets customers run most Mac OS X PowerPC applications seamlessly.”

> Apple supplied information on Rosetta.

At this time, Transitive can only acknowledge that it has supplied the technology for Apple’s Rosetta capability. Transitive will update this Apple Success Story when these restrictions are removed.

“ Transitive has successfully solved an age-old problem that software engineers have been trying to solve for years. This technology, which for the first time provides true instruction set architecture (ISA) independence, has tremendous potential to impact the entire computing industry, and its synergies with other emerging virtualization technologies are very exciting indeed. ”
