Osx-kvm-gpu-passthrough Access

Modern macOS VMs use the OpenCore bootloader. You will need to configure a config.plist that includes the necessary "arguments" to handle a passed-through GPU, such as agdpmod=pikera for certain AMD cards.

Use lspci -nn to find the Vendor and Device IDs for your GPU and its associated audio controller. osx-kvm-gpu-passthrough

Instruct the kernel to use the vfio-pci driver for those IDs at boot. This prevents your Linux desktop from "grabbing" the card. 3. The OSX-KVM Setup Modern macOS VMs use the OpenCore bootloader

A GPU gives you a display, but you still need a smooth mouse and keyboard. Passing through an entire USB Controller is better than passing through individual HID devices for zero latency. 5. Why Bother? Instruct the kernel to use the vfio-pci driver

While setup is complex, the results are unmatched. You get the stability of Linux as a base OS with the ability to run a "Bare Metal" speed macOS instance. For developers who want to stay in the Linux ecosystem but need to compile iOS apps or use Final Cut Pro, this is the ultimate solution.

Edit your GRUB configuration ( /etc/default/grub ) and add intel_iommu=on or amd_iommu=on to the kernel parameters.

Getting native graphics performance on a macOS virtual machine via KVM is the "holy grail" of virtualization. It turns a laggy VNC window into a fully functional workstation capable of video editing, Xcode development, and even light gaming.
