Install Mac OS 9 Using SheepShaver
May 04, 2019 With the old world rom file SheepShaver can run System 7.5.3 through Mac OS 9.0.4, with the new world rom file SheepShaver can run Mac OS 8.5 through 9.0.4. If you want to install 8.6 through 9.0.4, best use the new world rom. SheepShaver does nasty things when trying to allocate memory. If you search Emaculation.com SheepShaver forum for 'Cannot map second Kernel Data', you will find threads going back to 2009. Try different values for ram (like 128MB or 256MB or 512MB).
- Feb 12, 2008 As you know, PowerPC emulation of Mac OS/OS X is a pain in the butt. Sheepshaver only emulates up to Mac OS 9.0.4, while PearPC only emulates Mac OS X 10.1 and up. While looking on the Internet to find a way to emulate those version in between, I came across 'QEMU on Windows'. Normally, this an Intel X86 virtualize program.
- Jan 06, 2008 If you make a copy of a disk image say, from Toast 8 and create an.iso file, is there a way to make Sheepshaver believe that that.iso file is a disk that has been mounted? I know that folks can install Mac OS 9 from a disk image, and I'm attempting to mount multiple disks so I can play a multi-disk game without having to switch disks.
- SheepShaver is an open source emulator of PowerPC based Macintosh computers. Using SheepShaver it is possible to emulate a Macintosh computer capable of running Mac OS 7.5.2 through 9.0.4.
Alex walks you through this on YouTube.
Get the Files
- Download and install SheepShaver in a directory called “SheepShaver”.
- Download and unzip “New World PPC ROM“
- Download “Apple Mac OS 9.0.4 (ISO)” version 9.0 (and not 9.1 or 9.2)
- Download “gtk2-runtime-2.24.10-2012-10-10-ash.exe” – you will need these.
- SheepShaver comes with MAC OS 9 ROMs that don’t work. You can delete those.
- Copy the newworld86.rom to the SheepShaver directory.
- Rename the newworld86.rom to “Mac OS ROM” with no extension.
- Use 7zip to unzip the Apple Mac OS 9.0.4.7z file. It creates a Apple Mac OS 9.0.4.ISO file.
- Copy the Apple MacOS 9.0.4.ISO file to the SheepShaver directory.
- Make the Apple MacOS 9.0.4.ISO file read only: Right mouse click > Properties > Read Only. The Mac checks to see if the ISO is read only and errors if it is not.
- If you try to run SheepShaverGUI.exe without the GTK Runtime files, it will error with “The program can’t start because libgtk-win32-2.0-0.dll is missing…” So install these files by running gtk2-runtime-2.24.10-2012-10-10-ash.exe.
