Then there was the time when OS6x decided to delete half of my overheads for a class that I was teaching that evening. I still remember trying to work out how to eject the OS floppy after it got stuck in the drive on my Mac Plus. The interface is like a step back in time. The name of the emulator is a reference to ShapeShifter, a Mac II emulator for AmigaOS. Builds based on those contributions are listed on this site and in the SheepShaver forum. Development at that time was driven by Gwenole Beauchesne, who ported the emulator to Windows, Linux and Mac OS X.īeauchesne suspended his work on SheepShaver in April of 2008, although volunteers have contributed bug fixes and features since that time. In 2002, following the commercial decline of Be, SheepShaver was released as an open-source application. At that time, SheepShaver was a commercial product developed by Christian Bauer. SheepShaver began life in 1998 as a MacOS emulator for BeOS. SheepShaver is considered a good replacement for the Classic Environment which is not available in the most recent versions of Mac OS X….

Builds of SheepShaver are available for Mac OS X, Windows and Linux. Using SheepShaver (along with the appropriate ROM image) it is possible to emulate a PowerPC Macintosh computer capable of running Mac OS 7.5.2 through 9.0.4. SheepShaver is an open source PowerPC Apple Macintosh emulator.
