As of 2014, even OS X 10.9 is supported as the host system. There is an active developer community at E-Maculation who provide the latest builds for various operating systems. The last version from 2008 is also on the Gwenolé Beauchesne homepage, which is no longer available. The original developers, Christian Bauer and Marc Hellwig, only make very old versions available on their homepage.

Compared to a Power Mac G4 running at 400 MHz, Mac OS runs a little faster on an x86 system running at 3.2 GHz. With the JIT emulation, SheepShaver achieves an acceptable speed of about one eighth of the host system on non-PowerPC systems.

SheepShaver closes this gap: It is currently (as of 2014) the only way to use programs written for Mac OS on Intel-based Macs as well as on all Macs running Mac OS X 10.5 and newer. On Intel-based Macs, the first Mac OS X version for this architecture, 10.4 "Tiger", no longer had a Classic Environment. With the removal of the Classic environment in Mac OS X 10.5 "Leopard", Apple has taken away the built-in option of using old Mac programs on new Apple hardware, including on PowerPC Macs. On December 20th, PearPC version 0.4.0 was released with AltiVec support. SheepShaver was the first and until the end of 2005 the only available PowerPC emulator with G4 processor and AltiVec support. In 2008 he stopped working on SheepShaver. Gwenolé Beauchesne, a developer at Mandriva Linux, who had already contributed to Basilisk II in 1999, expanded the PowerPC-G4 emulator from 2003 to include “ Just-In-Time translation” and ported the emulator from BeOS to Linux, Mac OS X and Windows. ShapeShifter as well as Basilisk I and Basilisk II are largely made by Christian Bauer.Īfter BeOS was unsuccessful, SheepShaver was released as open source under the GPL in 2002. The name is an allusion to SheepShaver Shapeshifter, the 68K - Macintosh emulator for the Amiga.

Together with parts of the program code of Basilisk II, SheepShaver was created for BeOS in 1998, first as shareware, later as part of BeDepot. In order to be able to emulate newer versions of Mac OS, a PowerPC emulator was required. The last Mac OS to support this computer architecture is Mac OS 8.1. Since Shapeshifter and its further Basilisk II than 68k - Macintosh are designed emulator can use it only Mac OS run as guest operating systems for 68k Macintosh computers.
