Qemu is a versatile open source emulator capable of emulating various guest systems on various host systems. This description will only cover Qemu's capabilities with respect to the emulation of the PowerPC versions of Mac OS and OSX on the Intel archictecture. By running Qemu on Linux, MacOS, or Windows, users can currently emulate PowerPC Mac OS 9 up to Mac OSX 10.5 (including the classic environments in PPC OSX). Community-provided Qemu builds for OSX and Windows are available through our forum. These include builds from both the official source and experimental builds.
Work-in-progress setup guides for the Mac OS X and Windows builds of Qemu are available.
We also host a busy Qemu support forum.
For those so inclined there is this forum thread, in which the development history of Qemu's capability to run Mac OS and OSX can be retraced. Be warned, it is the longest thread in the forum…
