Need to run your PowerPC Applications ?
Mac OS X 10.6 Snow Leopard
- run PowerPC Applications on fast processors (eg. FreeHand)
Rosetta is a dynamic binary translator for Mac OS X that allows many PowerPC applications to run on certain Intel-based Macintosh computers without modification. Apple released Rosetta in 2006 when it transitioned the Macintosh platform from the PowerPC to Intel processor instruction set architecture. The name "Rosetta" is a reference to the Rosetta Stone, the discovery that made it possible to comprehend and translate Egyptian hieroglyphs.
Mac OS X v10.6 "Snow Leopard" does not include Rosetta by default but retains an option in the installer for the user to include it. It can also be automatically installed by the system if needed at a later time.
Mac OS X v10.7 "Lion" and OS X v10.8 "Mountain Lion" neither include nor support Rosetta at all. Therefore, with Lion and Mountain Lion, the current Macintosh platform does not support PowerPC applications.
