The exact name and locations varies by vendor and motherboard. Provided you have hardware that supports this process, it should be relatively straightforward.įirst, you want to enable virtualization extensions and IOMMU in your uefi. Vega and Fiji seem especially susceptible) 300 series cards may also have Mac OS specific compatibility issues.
A card without the Reset Bug (Anything older than Hawaii is bug free but it’s a total crap-shoot on any newer card. AMD’s refresh cycle makes this a bit more complicated to work out, but generally pitcairn chips and newer work fine - check your card’s bios for “UEFI Support” on techpowerup to confirm. A google search to make sure your card is compatible with Mac OS on Macs/hackintoshes without patching or flashing. Cards older than the 700 series may not have UEFI support, making them incompatible. High Sierra works up to 10 series cards, but Mojave ends support for 9, 10, 20 and all future Nvidia GPUs. A second discrete GPU (HEDT and F-sku CPUs only). Mainstream and budget chipsets only, HEDT unaffected.) ACS patch (only needed if you have many expansion cards installed in most cases. A second discrete GPU (most AMD CPUs do not ship with an igpu). ACS patch (lower end chipsets or highly populated pcie slots). Most recent available bios (ThreadRipper). Bios prior to AGESA 0.0.7.2 or a patched kernel with the workaround applied (Ryzen). The most recent mainline linux kernel (all platforms). Recent versions of Qemu (3.0-4.0) and Libvirt. The guest GPU also needs to support UEFI boot. If you plan on passing multiple USB controllers or NVMe devices it may also be necessary to check those with a tool like lspci. You can work around this problem if you already have 2 of the same GPU, but it isn’t ideal. You can check here (or here for AMD) to confirm you have 2 different device IDs. Usually this means just 2 different models of GPU, but there are some exceptions, like the AMD HD 7970/R9 280X or the R9 290X and 390X. 
A CPU that fully supports virtualization extensions (most modern CPUs barring the odd exception, like the i7-4770K and i5-4670K. A motherboard that supports IOMMU (most AMD chipsets since 990FX, most mainstream and HEDT chipsets on Intel since Sandy Bridge). 
A working install from part 1 of this guide, set up to use virt-manager. The vast majority of laptops are completely incompatible with passthrough on Mac OS. If you’ve arrived here without context, check out part one of the guide here. With that out of the way, let’s talk about what you need to get 3D acceleration up and running: If you find glaring errors or have suggestions to make the process easier, let us know on our discord. We’ve made every attempt to make this as straightforward as possible, but there’s a lot more ground to cover here than in the first part of the guide.
