Open source PowerPC Apple Macintosh emulator From Wikipedia, the free encyclopedia
Remove ads
SheepShaver is an open-source PowerPC Apple Macintosh emulator originally designed for BeOS and Linux. The name is a play on ShapeShifter,[1] a Macintosh II emulator for AmigaOS (made obsolete by Basilisk II). The ShapeShifter and SheepShaver projects were originally conceived and programmed by Christian Bauer. However, currently, the main developer is Gwenolé Beauchesne.

History
SheepShaver was originally commercial software when first released in 1998, but after the demise of Be Inc., the maker of BeOS, it became open source in 2002.[1] It can be run on both PowerPC and x86 systems; however, it runs more slowly on an x86 system than on a PowerPC system, because of the translation between the PowerPC and Intel x86 instruction sets.[2] SheepShaver has also been ported to Microsoft Windows. [citation needed]
As a free software, a few variants exist to simplify the installation process on Intel-based Macs:

Features
SheepShaver is capable of running Mac OS 7.5.2 through 9.0.4[1] (though it needs the image of an Old World ROM to run Mac OS 8.1 or below[5]), and can be run inside a window so that the user can run classic Mac OS and either BeOS, Intel-based Mac OS X, Linux, or Windows applications at the same time.
Although SheepShaver does have Ethernet support and CD-quality sound output,[1] it does not emulate the memory management unit.[2] This precludes support for versions 9.1 through 9.2.2, the final release. While adding MMU emulation has been discussed, the feature has not been added because of the time and effort required in implementing it.
