macOS KVM

Background

The purpose of this repository is to share my personalized (i.e. cleaned up, streamlined) QEMU KVM Hackintosh configuration using libvirt and OpenCore. This is an updated snapshot of what I am currently running on my relatively simple mini-ITX build.

Like many people, I began with general purpose KVM Hackintosh repositories such as:

kholia/OSX-KVM: Run macOS on QEMU/KVM. With OpenCore + Big Sur support now! Only commercial (paid) support is available.
foxlet/macOS-Simple-KVM: Tools to set up a quick macOS VM in QEMU, accelerated by KVM.

However, in trying to be as universal as possible, these prebuilt options leave you with a lot of extra configuration that will not be applicable to any particular setup. This also makes it more difficult to maintain the build, and can lead to a slower and overall less stable setup.

I kept reading/learning, eventually coming across some of the excellent more targeted resources out there:

Starting from my initial bloated configuration, I have slowly been able to trim down the unneeded components, toward the goal of maintaining the bare minimum configuration sufficient to achieve a functional build. As such, this configuration will not work on your system out of the box. Instead, it is here to show examples of the possible changes you might explore for your own rig.

Optimizations

OpenCore

Remove tons of unneeded legacy drivers (HiiDatabase.efi, NvmExpressDxe.efi, OpenUsbKbDxe.efi, Ps2KeyboardDxe.efi, Ps2MouseDxe.efi, UsbMouseDxe.efi, VBoxHfs.efi, XhciDxe.efi, mXHCD.kext).
Remove tons of legacy quirks/workarounds from OC config.plist (many more can be cut out!).
Remove some OC bells/whistles that I don't need and therefore just cause clutter (AudioDxe.efi, OpenCanopy.efi, OpenShell.efi, CrScreenshotDxe.efi).
Remove SSDT-DTGP.aml (not needed; can use the PMPM method instead for enabling power management in SSDT-PLUG.aml).
Remove SSDT-EC.aml (not needed; AppleBusPowerController attaches fine without it under Catalina, and KVM OVMF firmware doesn't have a real EC that needs to be turned off).
Remove SSDT-USBX.aml (not needed; USB power properties can be added to USB port mapping kext (USBmap.kext).
Remove MCEReporterDisabler.kext (not getting kernel panics, so not needed).
Remove SSDT-PLUG.aml (not needed for CPU power management, which the hypervisor manages).
Personalized USBmap.kext created with USBMap.

Libvirt

Clean up the messy PCI configuration (can cut down on the number of controllers to what is needed, delete the PCIe to PCI legacy bridge, etc.).
Remove default emulated USB 3 controller.
Remove additional unneeded USB 1/2 controllers.
