QEMU/Guests/Mac OS 9

Mac OS 9 is an operating system created and released by Apple in October of 1999. This was the final release in the classic Mac OS series. The OS was famously discontinued in 2002 with a mock funeral by Steve Jobs at the Apple Worldwide Developers Conference.

This article will describe in detail how to install Mac OS 9.2 with mouse drivers, sound, networking, and graphics. This tutorial should work with Mac OS 9.0 and 9.1 (which needs an additional flag; more details below).

Before you start
Versions of Mac OS prior to 10.4 (Tiger) did not run on x86 hardware. Instead, it used a PowerPC CPU. Because of this, it's not possible to run this OS with KVM, so we'll need to use pure software emulation, which may be a little slow but shouldn't be agonizing if you're on a newer PC.

You can grab a Mac OS 9.2.1 ISO from WinWorldPC.

Pre-installation
As always, the first thing we want to do is create the hard disk image by opening the Terminal or Command Prompt and typing this:

qemu-img create -f qcow2 macos9.img 2G

See this page for more information on how this command works.

You should see an output like this:



Now we're ready to go.

Starting up
Now, we'll start QEMU like this: qemu-system-ppc -M mac99 -m 512 -hda macos9.img -cdrom /path/to/macos-9-cd.iso -netdev user,id=mynet -device sungem,netdev=mynet -device usb-mouse -device usb-kbd -boot d

A breakdown of this command:  is the name of the QEMU emulator, of course. tells it to emulate a "Mac99" model (which is a G4 Mac). QEMU also supports a Beige PowerMac G3. You can type  for a full list. adds 512 MB of RAM to the machine. The system becomes really unstable with more than 1 GB of RAM so I recommend setting this to about 896 MB (the maximum supported by Mac OS 9) at most. is the hard drive. adds a CDrom drive, which needs to be changed to point to the Mac OS ISO. adds a virtual "user" network and sets up some network configuration. It'll also attach to your host's LAN. adds a virtual NIC (in this case, a SunGEM network card) and assigns it to the virtual network specified before. and  add a USB mouse and keyboard which will allow for much better input (especially if you are hosting this on CollabVM). And finally,  tells the machine to boot from the CD-ROM drive.

If you are installing Mac OS 9.0 or 9.1, you will also need to add  to the flags for it to work.

Installation
With all that done, we are now ready to start.

When you start QEMU, you should see a yellow screen with some details like this:



The system should begin starting up after a few seconds:



It usually takes around a minute to start, but if you're on a slower/older machine it may take several minutes. When it's done it should drop you into a live Mac OS 9 environment like this:



Click the "Utilities" folder. Open the "Drive Setup" utility and initialize the volume (labeled ).



It'll warn you that it will destroy all data on the volumes. Click Initialize and proceed. It will partition the disk, and then we can proceed with the installation. Go back to the root CD folder and click "Install Mac OS 9.2.1" (or whatever version). Click Continue, make sure the Destination Disk is the one you just initialized, accept the software license agreement, and click "Start" to begin the installation.



The system will now install. It will give an ETA of about 7 minutes usually but it might take longer to actually install. Just sit back, let it do its thing, go watch some YouTube videos or something while it does this.



When it's done installing you will get a message box asking if you want to exit or continue to install other software. Choose "Continue" and close out of QEMU (press Ctrl+ALT+G to release the mouse grab). Change the  flag to   so that it boots to the new image, like so:

qemu-system-ppc -M mac99 -m 512 -hda macos9.img -netdev user,id=mynet -device sungem,netdev=mynet -device usb-mouse -device usb-kbd -boot c

You may also remove the CD rom if you want. You will see the same yellow boot screen as before, and if all went well, you should see this (you may have to jiggle your mouse a bit to make it actually load):



And if all went well, you should be in the desktop! Hooray!



You may have a "Setup Assistant" appear. You can go through and set everything up or close it, it doesn't matter much, though it will help you set up some basic network functions like shared folders and the like, so I recommend it. It's a very simple wizard.

Sound
Unfortunately, the stock QEMU does not come with proper sound drivers for Mac OS 9, so we'll need to build a fork of QEMU that adds these sound card drivers. This section will be technically advanced and is only recommended for more experienced users. The instructions change depending on your OS.

Compiling on Linux
Clone the source code tree like so:

git clone --recursive -b screamer https://github.com/mcayland/qemu.git qemu-screamer

cd qemu-screamer/

Install the proper build dependencies. This varies from distro to distro, so I included a table with a few example commands:

into the folder. We'll configure the build here. We're only going to compile the PowerPC version of QEMU to save time, though if you want to build every version, just remove the  flag at the very end. Execute the following command:

./configure --target-list=ppc-softmmu

Finally, build QEMU:

cd build/ make -j$(nproc)

Afterwards, you'll find the proper  in the   folder.

Compiling on macOS
First things first, this requires Homebrew. If you don't have it, install it by following the guide on the official website.

Clone the source code tree like so:

git clone --recursive -b screamer https://github.com/mcayland/qemu.git qemu-screamer

cd qemu-screamer/

Then, install all the build dependencies through Homebrew:

brew install libffi gettext glib pkg-config autoconf automake pixman ninja meson gnutls jpeg libpng libslirp libssh libusb lzo ncurses nettle snappy vde

Now,  into the folder. We are going to configure the build. We are only going to compile the PowerPC version of QEMU to save time, though if you want to build every version of QEMU, just remove the  flag at the very end. Execute the following command:

PKG_CONFIG_PATH="$(brew --prefix)/opt/ncurses/lib/pkgconfig" ./configure --target-list=ppc-softmmu

Finally, build QEMU:

cd build/ make -j$(sysctl -n hw.ncpu)

Afterwards, you'll find the proper  in the   folder.

Compiling on Windows
We will need to download and install the latest version of MSYS2. Follow the instructions on the page.

A terminal should open when the installation finishes, if not just open it from the Start menu. When the terminal is open, we'll update MSYS2's packages by running:

pacman -Syu

When the updates are installed, the terminal will close. Open it again and run the following command to finish updating the packages:

pacman -Su

Now, install the build dependencies for QEMU:

pacman -S --needed base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-glib2 mingw64/mingw-w64-x86_64-gtk3 mingw64/mingw-w64-x86_64-SDL2 git python python-setuptools ninja

When this is finished, close the MSYS2 terminal and open the MinGW terminal (should be in the Start menu), and run the commands below to prepare the build environment for QEMU's build scripts:

cp -v /mingw64/bin/x86_64-w64-mingw32-gcc-ar.exe /mingw64/bin/x86_64-w64-mingw32-ar.exe cp -v /mingw64/bin/x86_64-w64-mingw32-gcc-ranlib.exe /mingw64/bin/x86_64-w64-mingw32-ranlib.exe cp -v /mingw64/bin/windres.exe /mingw64/bin/x86_64-w64-mingw32-windres.exe cp -v /mingw64/bin/nm.exe /mingw64/bin/x86_64-w64-mingw32-nm.exe cp -v /mingw64/bin/objcopy.exe /mingw64/bin/x86_64-w64-mingw32-objcopy.exe

Now it's time to clone the source tree like so:

git clone --recursive -b screamer https://github.com/mcayland/qemu.git qemu-screamer

cd qemu-screamer/

Now we'll configure the build. To save time we only build the PowerPC QEMU target, but if you want to build all of them, just remove the  flag from the end. Also, unlike with macOS/Linux builds, we'll be disabling the GTK UI since it has mouse input issues, as well as DirectSound audio backend because it results in audio issues with OS X (though not Mac OS 9).

./configure --cross-prefix=x86_64-w64-mingw32- --disable-gtk --enable-sdl --audio-drv-list=sdl --target-list=ppc-softmmu

Now we build QEMU:

cd build/ make -j$(nproc)

Afterwards, you'll find the proper  in the   folder.

Software
Now that we have our system set up, we'll probably want to install some software. Fortunately, a lot of it was preserved thanks to the efforts of Macintosh Garden, Macintosh Repository, and the Internet Archive. Pretty much every major software for OS 9 is on Macintosh Garden and Repository, so I recommend checking those ones out first. Some convenient and interesting software is listed below.

Note: You may have to right click some of the links and click "Save link as...". This is due to a recent change in policy in browsers such as Chrome regarding HTTP links.


 * Classilla (Firefox 2 fork)
 * Internet Explorer 5.1.7 (final version of IE for OS 9)
 * Official Macintosh Garden Sherlock Plugins
 * Virtual CD/DVD-ROM Utility
