Success starts with your hardware. macOS has very strict driver support compared to Windows or Linux. This is the most critical factor. AMD (Recommended): In virt-manager or your Libvirt XML, you must
Use lspci -nn to find the Vendor and Device IDs for your GPU and its associated audio controller. Common Pitfalls Some AMD cards (like the Vega
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
