The Classic environment, and thus any non-Carbon application built for Mac OS 9 or earlier.Pre-existing PowerPC versions of Apple 'Pro' media-production applications (such as Final Cut Pro, Motion, Aperture, and Logic Pro) are not supported by Rosetta and require a 'crossgrade' to a universal binary version to work on Rosetta-supported Intel-based Macs. According to Apple, applications with heavy user interaction but low computational needs (such as word processors) are well suited to translation via Rosetta, while applications with high computational needs (such as AutoCAD, games, or Adobe Photoshop) are not. Therefore, applications that rely on G5-specific instruction sets must be modified by their developers to work on Rosetta-supported Intel-based Macs. It translates G3, G4, and AltiVec instructions however, it does not translate G5 instructions.

Rosetta is part of Mac OS X for Intel operating systems prior to Lion. Rosetta Mac transition to Intel processors
Rosetta 2 is included as of macOS Big Sur to aid in Apple's transition to ARM processors from Intel processors. Joined Messages 8,619 Motherboard Z370N WIFI CPU Core i7 8700K Graphics Radeon RX Vega 56 Mac Classic Mac, Mobile Phone. Therefore, with Lion and later releases, the Intel Macintosh platform does not support PowerPC applications. Rosetta is neither included nor supported in Mac OS X v10.7 'Lion' or later. Rosetta is not installed by default in Mac OS X v10.6 'Snow Leopard', but can be retained as an option via the installer or Apple Software Update for users who need to run PowerPC applications.
It has no graphical user interface, which led Apple to describe Rosetta as 'the most amazing software you'll never see.' Rosetta is based on QuickTransit technology. The name 'Rosetta' is a reference to the Rosetta Stone, the discovery that made it possible to comprehend and translate Egyptian hieroglyphs. It was initially included with Mac OS X v10.4.4 'Tiger', the version that was released with the first Intel-based Macs, and allowed many PowerPC applications to run on certain Intel-based Mac computers without modification. for macOS.Īpple released the first version of Rosetta in 2006 when it changed the instruction set architecture of the Macintosh platform from the PowerPC to the Intel processor. Rosetta is a dynamic binary translator developed by Apple Inc.
