SheepShaver – a Mac OS run-time environment that allows you to run classic PowerPC Mac OS applications on a different operating system, such as Mac OS X, Windows, Linux or BeOS. If you are using a PowerPC-based system, applications will run at native speed (i.e. with no emulation involved). There is also a built-in PowerPC emulator for non-PowerPC systems.
SheepShaver began life in 1998 as a MacOS emulator for BeOS. At that time, SheepShaver was a commercial product developed by Christian Bauer. In 2002, following the commercial decline of Be, SheepShaver was released as an open-source application. Development at that time was driven by Gwenole Beauchesne, who ported the emulator to Windows, Linux and Mac OS X.
Beauchesne suspended his work on SheepShaver in April of 2008, although volunteers have contributed bug fixes and features since that time. Builds based on those contributions are listed on this site and in the SheepShaver forum.
The name of the emulator is a reference to ShapeShifter, a Mac II emulator for AmigaOS.
SheepShaver is distributed under the terms of the GNU General Public License (GPL). However, you still need a copy of MacOS and a PowerMac ROM image to use SheepShaver. If you’re planning to run SheepShaver on a PowerMac, you probably already have these two items.
