one of my fellow Rebel brothers posted that on our web-site for another member having computer problems also:
The sheep saver section in oberin holds one OS 9 called Sheep saver disk image. Works in Yosemite so i guess it should work in your computer as well.
and since he is IG, I think that works. Hope it helps
just to bump my first post
you will need to download it via the mega.co.nz download link i posted. Should be in one of the sticky threads regarding sheepshaver. I was in the process of making a better method of emulation, but things became busy for me.
