Follow the install and setup guide of Sheepshaver here. In summary:
- Download SheepShaver latest version zip
- Download the ‘SheepSaver folder’ zip that contains required scripts
- Move the SheepSaver.app into the SheepShaver folder
- Download a Mac OS 9 install cd iso (e.g. from Machintosh Garden) – 9.0.4 works with SheepShaver – place in SheepShaver folder
- Download a ROM (e,g. ‘New World PPC ROM’), unzip, move into SheepShaver folder and rename it ‘Mac OS ROM‘
Start SheepShaver, you’ll get the missing startup disk:

Open Preferences:
- Create a disk
- Point ROM file to the ROM you downloaded
- Change the Unix root to point to a shared folder
- Add the ,toast file for the OS 9 install cd and select ‘cdrom’
- Update the RAM
- Set the video to Windowed

Save and Quit, and then restart!
If the .toast file is not bootable it might be compressed. Use MacOS Disk Utilities, Image/Convert, select ‘DVD/CD Master’ as the format, and save it as a ‘.cdr’ file. When done, rename the file to ‘.iso’ and add that as a cdrom disk in SheepShaver Preferences instead of the ‘.toast’ file.
Restart!
Format the empty disk when prompted:

Double-click the ‘Mac OS Install’ app to start the install from the mounted cd iso image, to the disk:


If the installer gets stuck here:

… quit and start the install again, press the Option button and uncheck the ‘Update Apple Hard Disk Drivers’ option (mentioned in the Sheepsave install guide, and on the forum here)
