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.

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. SheepShaver started as a commercial project in 1998 but is now open source since 2002. What is SheepShaver PPC emulator (for Windows + Mac OS X)? SheepShaver is a PowerPC (PPC) emulator which allows you to run Mac OS 7.5 up to Mac OS 9.0.4 on various platforms, such as on Windows.
