– This is an odd resolution but does work, again an extra step but a simple fix. The procedure to get it running is simply to copy the program (only the SheepShaver application itself!) to the desktop, remove the old program in the SheepShaver folder and move the new copy from the desktop to the SheepShaver folder.

There is an issue with macOS 10.12 Sierra (in fact with an additional new security feature in Sierra) that prevents a newly installed SheepShaver to run.It is not overly complex and should not be a barrier to use. – Basically you need to make disc images or download disc images for OS 9 install or any other CDs you wish to use. Compressed and read-only formats will not work. Make sure you choose either “read/write” (.dmg) or “DVD/CD Master” (.cdr) for the format. You can create an image from a CD with Disk Utility. OSX 10.8 and later prevents mounting of physical CD-ROMs in SheepShaver but images created from CD-ROMs still work fine.With this assumption I can point out some relevant quirks with SheepShaver that could trip you up but are easily resolvable.

Sheep Shaver running OS 9.0.4 Classic on High Sierra Having read around the subject of running OS 9 in an emulator I settled on using a free piece of software called SheepShaver this allows you to emulate up to OS 9.0.4 (anything above this will not run). So there is a nostalgia in running Mac OS 9 again and having easy (possibly not fully legally) access to a slew of old Mac software. This harps back to my introduction to Macs, when I was first fiddling about with them the only ones I could afford were second hand Performa 6300 or early Power Mac G4s (that I wish I still had now, glances at eBay watch list).

I will focus on Classic Mac emulation in this article as the Amiga side is a bit more involved and I am still learning the ropes on that (look out for a followup post later). I have been working on Classic Mac and Amiga emulation, with a slew of great guides and excellent free software. Giving me the opportunity to play about with some emulation options without disturbing my main work Mac. Classic Mac Emulation On macOS, having just resurrected my 2008 Mac Pro from the doldrums, it has now become a permanent feature in the office / retro basement.
