Mac OS 9 install on Sheepshaver (MacOS)

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)
