Install Snow Leopard in Qemu and UTM

[startergo]

1. Install Qemu:

brew install qemu

If you want to install qemu with options:

brew uninstall qemu
sudo port clean qemu
sudo port install qemu +spice_protocol +spice +ssh +usb +vde +vnc

2. In terminal clone the repo:

git clone https://github.com/royalgraphx/LegacyOSXKVM

3. Modify all Snow Leopard .sh scripts by replacing accel=kvm with accel=hvf.
4. Replace /usr/share/edk2-ovmf/x64/OVMF_CODE.fd with ~/LegacyOSXKVM/ovmf/OVMF_CODE.fd (providing you cloned the repo in the ~ directory).
5. Download sl_utm.qcow2 to the ~/LegacyOSXKVM/osxinstaller/sl_utm.qcow2 directory.

6. Download the 1920x1080-OpenCoreSLeopard.img file to the ~/LegacyOSXKVM/opencore/1920x1080-OpenCoreSLeopard.img directory:

7. Open Terminal and navigate to the cloned repository and start Qemu:

cd LegacyOSXKVM && qemu-img create -f raw harddrives/macintosh.img 40G && ./SLeopard-Install-HiRes.sh

8. Disable debug logging in the Opencore by changing Target to 0 in the Config file

Spoiler: Target

Once installed you can use the other scripts like SLeopard-Boot-HiRes.sh for booting.
Caveat: audio: Could not create a backend for voice `adc'
Enjoy!

Now that you have the QEMU Snow Leopard you can create easily a UTM Snow Leopard. It provides 7MB Vram rather than 3MB from QEMU:

~/LegacyOSXKVM/harddrives/macintosh.img

Once you install the Virtual Machine you can add and install VMQemuVGA.kext to /Library/Extensions or the kexts in the OpenCore directory on the EFI drive which mounts automatically on boot. You can instal then Vmware tools attached.

sudo defaults write com.apple.loginwindow LoginHook /usr/bin/mDNSresponder_fix.sh

For Snow Leopard you have to fix the expired certificates as well:

A login hook tells Mac OS X to execute a certain script when a user logs in. Unlike Startup Items that open when a user logs in, a login hook is a script that executes...

Surprisingly Snow Leopard in UTM runs much smoother than in Parallels. I can access local networks and even copy/paste if I run Remote Desktop to the VM.
