Success starts with your hardware. macOS has very strict driver support compared to Windows or Linux. This is the most critical factor. AMD (Recommended):
However, it is not a "plug-and-play" process. It requires specific hardware and precise configuration of the Linux host. 1. Hardware Requirements & Compatibility 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 Success starts with your hardware
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. AMD (Recommended): However, it is not a "plug-and-play"
Some AMD cards (like the Vega series) don't reset properly when the VM shuts down. You might need the vendor-reset kernel module to fix this.
