SheepShaver is an open source PowerPC Apple Macintosh emulator. 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. Builds of SheepShaver are available for Mac OS X, Windows and Linux.

SheepShaver is considered a good replacement for the Classic Environment which is not available in the most recent versions of Mac OS X.

Important:
SheepShaver requires users to supply a ROM image and a copy of Mac OS.

If you have an existing SheepShaver setup, you can simply replace the application with the new application.
If you use an older keycodes file, you will also need to replace that file with the new one: https://ronaldpr.home.xs4all.nl/sheepshaverforum/keycodes.zip

For a new setup, also download the SheepShaver folder.
For more information see the revised setup manual
