This allows lines of 68k and PPC code to be interspersed within the same fat binary. By contrast, the 68k emulator accesses the very lowest levels of the OS by being at the same level as, and tightly connected to, the Mac OS nanokernel on PPC Macs, which means that the nanokernel is able to intercept PowerPC interrupts, translate them to 68k interrupts (then doing a mixed mode switch, if necessary), and then execute 68k code to handle the interrupts. Rosetta is a user-level program and can only intercept and emulate user-level code. The reason for Rosetta's reduced compatibility compared to Apple's earlier 68k emulator for PPCs lies within its implementation.

Applications that require precise exception handling.Code that inserts preferences into the System Preferences pane.The Classic environment, and thus any non-Carbon application built for Mac OS 9 or earlier.Rosetta also does not support the following: Apple advised that applications with heavy user interaction but low computational needs (such as word processors) would be best suited to Rosetta, while applications with high computational needs (such as AutoCAD, games, or Adobe Photoshop) would not.

Although most commercial software for PowerPC-based Macs were compatible with these requirements, any applications that relied on G5-specific instruction sets had to be modified by their developers to work on Rosetta-supported Intel-based Macs. Rosetta translates G3, G4, and AltiVec instructions, but not G5 instructions. Rosetta is neither included nor supported in Mac OS X v10.7 'Lion' or later, which therefore cannot run PowerPC applications.

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. 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. It was initially included with Mac OS X v10.4.4 'Tiger', the version that was released with the first Intel-based Macs, and allows many PowerPC applications to run on certain Intel-based Mac computers without modification. Rosetta Mac transition to Intel processorsĪpple released the first version of Rosetta in 2006 when it changed the instruction set architecture of the Macintoshplatform from the PowerPC to the Intel processor. The name 'Rosetta' is a reference to the Rosetta Stone, the artifact which enabled translation of Egyptian hieroglyphs. The second version, introduced in 2020, is a component of macOS Big Sur to aid in the Mac transition to Apple Silicon from Intel processors. The first version of Rosetta, introduced in 2006, allows PowerPC applications to run on Intel-based Macs.

It gives developers and consumers a transition period in which to update their application software to run on newer hardware. for macOS, an application compatibility layer between different CPU architectures. Rosetta is a dynamic binary translator developed by Apple Inc.

As a result, many 'old school' Mac users officially will have to upgrade - or find replacements for - some applications should they be interested in running the. Consequently, no PowerPC Mac OS X applications will operate on Mac OS X Lion. Unfortunately, Mac OS X 10.7 'Lion' does not support the 'Rosetta' environment for PowerPC applications.Publisher's note: When Mac OS X 10.7 Lion ships later this year, Rosetta, which has allowed Intel-based Macs to run PowerPC (PPC) software since 2006, will no longer be part of the Mac OS.This will not only render apps written prior to the Intel switch unusable - it will also prevent software installers and application updaters that depend on PPC code from running.PowerPCbinary translation (original version) PowerPC application (Microsoft Word for Mac 2004) running on OS X for Intel in Rosetta
