It started out on PowerPC processors but later transitioned onto Intel processors with Mac OS X Leopard (10.5) the last to natively support the PowerPC architecture and Snow Leopard (10.6) the last to support PowerPC applications on Intel-based Macs. The first generation Intel-based Macintoshes were released in January 2006 with Mac OS X 10.4.4 Tiger, and Steve Jobs announced the last models to switch in August 2006, the Mac Pro available immediately and with the Intel Xserve available by October 2006. The Xserve servers were available in December 2006.

Rosetta is a dynamic binary translator developed by Apple Inc. for macOS, an application compatibility layer between different CPU architectures. It gives developers and consumers a transition period in which to update their application software to run on newer hardware.
The first version of Rosetta, introduced in 2006, allows PowerPC applications to run on Intel-based Macs. 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.[1] The name 'Rosetta' is a reference to the Rosetta Stone, the artifact which enabled translation of Egyptian hieroglyphs.[2]
Rosetta[edit]
Mac transition to Intel processors |
---|
Apple 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. 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 is based on QuickTransit technology.[3] It has no graphical user interface, which led Apple to describe Rosetta as 'the most amazing software you'll never see'.[4] 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.[5] Rosetta is neither included nor supported in Mac OS X v10.7 'Lion' or later, which therefore cannot run PowerPC applications.[5]
Rosetta translates G3, G4, and AltiVec instructions, but not G5 instructions. 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. 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.[6]
Rosetta also does not support the following:[7]
- The Classic environment, and thus any non-Carbon application built for Mac OS 9 or earlier
- Code that inserts preferences into the System Preferences pane
- Applications that require precise exception handling
- Screen savers
- Kernel extensions and applications that depend on them
- Bundled Java applications or Java applications with JNI libraries that cannot be translated
- Java applets in Rosetta-translated applications, meaning that a native Intel web browser application, rather than a legacy PowerPC version, must be used to load Java applets
The reason for Rosetta's reduced compatibility compared to Apple's earlier 68k emulator for PPCs lies within its implementation. Rosetta is a user-level program and can only intercept and emulate user-level code. 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. This allows lines of 68k and PPC code to be interspersed within the same fat binary.
Rosetta 2[edit]
Mac transition to Apple Silicon |
---|
Rosetta 2 is included as of macOS Big Sur to aid in the Mac transition to Apple Silicon from Intel processors.[1][8] In addition to the just-in-time (JIT) translation support available in Rosetta, Rosetta 2 includes support for translating an application at installation time.[9]
