Basilisk II is an Open Source 68k Macintosh emulator, that is, it enables you to run 68k Mac OS software on you computer, even if you are using a different operating system.

The latest version of MacOS that can run on Basilisk II is MacOS 8.1. PLEASE NOTE that Basilisk II does not include a copy of MacOS or a Macintosh ROM. You will need to supply your own copy of the operating system or installation disk as well as a ROM file extracted from a 68k-based Macintosh computer (not a PowerPC one!)
