PowerPC Macintosh Emulator
Description
This page is about qemu-system-ppc: An emulator of the Apple Beige Power Mac G3 and Sawtooth Power Mac G4.
Note: Information below true for qemu-system-ppc builds as of 05-01-2019
Hardware options
Recent builds of qemu-system-ppc default to emulating a PowerPC Mac G4, Mac Model PowerPC3,1.
The machine model selector on the command line (-m) has three options:
| Machine model selector | Provides |
| -m mac99,via=pmu | pmu power management, providing USB mouse and keyboard |
| -m mac99,via=pmu-adb | pmu power management with adb bus for older OSs not supporting USB |
| -m mac99,via=cuda | cuda power management with adb bus (this is the default) |
Optional commands:
| Optional commands | Default | Provides | |
| -prom-env "auto-boot?=true" | yes | Automatic boot at openbios prompt | |
| -prom-env "boot-args=-v" | no | Verbose start-up of OSX guests | |
| -prom-env "vga-ndrv?=true" | yes | On the fly resolution/colour depth switching for Mac OS/OS X guests | |
| -device VGA,edid=on | no | Provides additional screen resolutions for Mac OS/OS X guests |

Build directions
./configure --target-list=ppc-softmmu && make
Due to mouse issues when using the default GTK GUI in Windows, it is advisable to use the SDL-based GUI when compiling on that platform:
./configure --target-list=ppc-softmmu --enable-sdl && make
Pre-built binaries for Windows and OSX

Guest installation instructions
Mac OS/Mac OSX
Mac OS 9.x to Mac OS X 10.4
Command-line options to install Mac OS 9:
./qemu-system-ppc -L pc-bios -boot d -M mac99 -m 512 -hda <hd image file> -cdrom <iso file of installation media> -netdev user,id=mynet0 -device sungem,netdev=mynet0
Mac OS X 10.5
Command-line options to install Mac OS X 10.X:
./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu -m 512 -hda <hd image file> -cdrom <iso file of installation media> -netdev user,id=mynet0 -device sungem,netdev=mynet0
Mac OS X Server 1.2v3
Installation requires several steps:
Step 1: boot from installation CD, use disk utility to partition disk as Apple Server, start the installation and let it fail. Quit Qemu and reboot with command line in step 2.
./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu-adb -m 256 -net none -prom-env "auto-boot?=true" -prom-env "vga-ndrv?=true" -prom-env "boot-args=-v" -cdrom OSXServer1.2v3.iso -hda OSXServer1.2v3.qcow2
Step 2: initial installation (note machine and CPU, otherwise no desktop is shown).
./qemu-system-ppc -L pc-bios -boot d -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=false" -net none -hda OSXServer1.2v3.qcow2 -cdrom OSXServer1.2v3.iso
At the boot prompt enter "boot cd:9,\\:tbxi" Initial installation starts. Quit Qemu after completion.
Step 3: Installation continued. Boot with the following command line to complete the installation.
./qemu-system-ppc -L pc-bios -boot c -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=true" -net none -hda OSXServer1.2v3.qcow2 -cdrom OSXServer1.2v3.iso
Step 4: Boot the installed system:
./qemu-system-ppc -L pc-bios -boot c -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=true" -net none -hda OSXServer1.2v3.qcow2 -cdrom OSXServer1.2v3.iso
32 Bit PowerPC Linux
Lubuntu 14

Fedora 12
Installing:
./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu -m 1024 -net nic,model=sungem -net user -hda fedora12.qcow2 -cdrom Fedora-12-ppc-DVD.iso -g 1024x768x16

Debian 10 (Buster)
Note: To get a graphical desktop, at software selection, remove the default desktop environment and install only Xfce
Installing:
./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu -m 1024 -net nic,model=sungem -net user -hda debian10.qcow2 -cdrom debian-10.0-powerpc-NETINST-1.iso -g 1024x768x8
Running:
./qemu-system-ppc -L pc-bios -boot c -prom-env "boot-device=hd:,\yaboot" -prom-env "boot-args=conf=hd:,\yaboot.conf" -M mac99,via=pmu -m 1024 -net nic,model=sungem -net user -hda debian10.qcow2 -g 1024x768x32
At the Linux boot prompt enter "Linux modprobe.blacklist=bochs_drm"
Pre-installed images of Debian 6 (Squeeze) and 7 (Wheezy) (both minimal and with desktop) can be found here: https://people.debian.org/~aurel32/qemu/powerpc/
These images boot with:
./qemu-system-ppc -L pc-bios -boot c -M mac99,via=pmu -m 1024 -net nic,model=sungem -net user -hda debian_wheezy_powerpc_desktop.qcow2 -g 1024x768x32
OpenSuse 11
Installing:
./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu -m 512 -net nic,model=rtl8139 -net user -hda opensuse11.qcow2 -cdrom opensuse11.iso -g 1024x768x8
Once the license screen appears, press Ctrl-Alt-Shift-X to open a terminal. Follow https://en.opensuse.org/SDB:Install_openSUSE_on_an_Apple_PPC_computer to create partitions with pdisk. Write the map after partitioning and continue with Yast. Once Yast arrives at partitioning, select Expert partitioning, select the Hard disk and click Rescan disk.
Leave hda2 as it is.
Edit hda3 to format as Ext2, mount at /boot and set fstab option to: Mount in /etc/fstab by to Device Path (instead of Device ID)
Edit hda4 to format as Swap and set fstab option to: Mount in /etc/fstab by to Device Path (instead of Device ID)
Edit hda5 to format as Ext3, mount at / and set fstab option to: Mount in /etc/fstab by to Device Path (instead of Device ID)
Accept the partitioning and continue with formatting. Continue installing. There will be an error while the boot manager is being installed. Ignore it, do not retry and wait for the installation to finish and the system reboots. Quit Qemu at the openbios screen and edit your command line:
./qemu-system-ppc -L pc-bios -boot c -M mac99,via=pmu -m 512 -net nic,model=rtl8139 -net user -hda opensuse11.qcow2 -cdrom opensuse11.iso -g 1024x768x32
Debugging tips
Command line options
-d unimp,guest_errors
(logs unimplemented features and guest errors to stdout)
-trace 'pmu_*'
(logs all PMU accesses to stdout)
-trace 'usb*'
(logs all USB accesses to stdout)
Macsbug
Macsbug can be used to tell you what exactly stopped booting. The link for it is below.
Mac OS 9.2 comes with a built-in debugger. To use it, set the OpenBIOS variable “APPL,debug”:
Via QEMU's command-line options:
-prom-env aapl,debug=2000000
In OpenBIOS type:
dev /
2000000 encode-int *Note: the number can be replaced with the many options available
“ AAPL,debug” property
then to boot from a cd type:
boot cd:,\\:tbxi
To boot from a hard drive image:
boot hd:,\\:tbxi
Debugging qemu-system-ppc with GBD on an x86 Linux host
To build gdb-powerpc-linux on Linux, you need the normal build tools such as GCC installed. Download the GDB source code. Version 7.9 is reported to work: http://ftp.gnu.org/gnu/gdb/gdb-7.9.tar.gz Unpack it and cd into the dir, then build and install with:
./configure -target=powerpc-linux --enable-sim-powerpc make && sudo make install
Launch qemu-system-ppc(64) with -s and -S. Qemu will pause and listen on port 1234 for GDB. Set -prom-env "auto-boot?=false" --nographic on the command line for the Qemu instance to be debugged.
qemu-system-ppc -s -S -prom-env "auto-boot?=false" --nographic
Open another terminal and launch the GDB you just built:
gdb-powerpc-linux target remote localhost:1234 continue
You can set a breakpoint in GDB, like this:
break *0x20dccc
Type "boot" in the terminal running Qemu.
Emulated hardware issues
Mac OS
-Only Mac OS 9.x support sound well. Use an experimental build.
-Mac OS 9.x will not boot with 64 Mb or less memory. They will also not boot with more than 1024 Mb.

How do I help
QEMU has many systems that can always be improved. Here is a brief list of possible areas you may want to work on:
- Documentation
- Testing
- Fixing operating system compatibility issues
- PowerPC emulation
- User interface
- OpenBIOS (firmware)
- Implement a 3D video card
- Improve various hardware (via-cuda, ata controller, etc..)
Knowledge in these areas could help:
- PowerPC Assembly
- 68K Assembly
- Embedded Programming
