Rosetta is a lightweight dynamic translation emulator for Mac OS X distributed by Apple. It enables applications compiled for the PowerPC family of processors to run on Apple systems that use Intel processors. It is based on Transitive Corporation's QuickTransit technology. It is a key part of Apple's strategy for the transition of their Macintosh line from PowerPC to Intel processors, enabling pre-existing Mac OS X software to run on the new platform without modification. The name is a reference to the Rosetta stone, whose discovery made it possible to comprehend and translate Egyptian hieroglyphs.
