However, you still need a copy of MacOS and a Macintosh ROM image to use Basilisk II. That is, it enables you to run 68k MacOS software on you computer, even if you are using a different operating system. Either drag or add to the list of hard drives and see if it mounts OK. Basilisk II is an Open Source 68k Macintosh emulator.

Basilisk II: An emulator targeting the Mac Classic and Mac II lines. In order for image files to mount, they need to be in a suitable format, i.e. A quick way to distinguish an Old World from a New World Mac is that all New. If your B-II session is windowed and not full-screen you can also drag an image file from your host computer into the B-II window and it will mount as a disk drive this way, too. This way large image files will mount on the emulated desktop as a hard drive disk and you can access the contents that way, negating the need to create a drive for it. You can also, mount large image files in the emulator by adding them to the list of drives before starting an emulated session. You can easily create further classic Mac 'hard disk' image files much larger than 500 MB and mount them in the same emulated session. It is very dangerous to work with files in the 'unix' drive other than as a 'go-between' as classic Mac files can be made unusable if run from within this drive. The 'unix' drive should only be used to transfer files between the emulated hard drive and the host computer. 'cannot be mounted from the disk it is currently on'
