PowerPC application (Microsoft Word for Mac 2004) running on OS X for Intel 10.4.4–10.6.8 (Intel) Website Rosetta is a discontinued for that allowed many applications to run on certain -based computers without modification. Released Rosetta in 2006 when it the of the Macintosh from the PowerPC to the Intel processor. The name 'Rosetta' is a reference to the, the discovery that made it possible to comprehend and translate. Rosetta is based on technology. It has no, which led Apple to describe Rosetta as 'the most amazing software you'll never see.' Rosetta was initially included with 'Tiger', the version that was released with the first Intel-based Macintosh models.

Rosetta is not installed by default in 'Snow Leopard', but can be retained as an option via the installer or for users who need to run PowerPC. Rosetta is neither included nor supported in 'Lion' or later. Therefore, with Lion and later releases, the current Macintosh platform does not support PowerPC applications.

As the others have said, a 'Windows' emulator on a PPC Mac is a lot of work, as the entire CPU archetecture must be emulated and every single instruction converted. That is why it is painfully.

• • • Rosetta is part of Mac OS X for Intel operating systems prior to Lion. It translates,, and instructions; however, it does not translate instructions.

Therefore, applications that rely on G5-specific instruction sets must be modified by their developers to work on Rosetta-supported Intel-based Macs. According to Apple, applications with heavy user interaction but low computational needs (such as ) are well suited to translation via Rosetta, while applications with high computational needs (such as, games, or ) are not. Pre-existing PowerPC versions of Apple 'Pro' media-production applications (such as, Motion, Aperture, and Logic Pro) are not supported by Rosetta and require a to a version to work on Rosetta-supported Intel-based Macs.
