  > The big roadblock that we've hit is that arm64 macOS has no software rasteriser for rendering the GUI. The result is that unless you implement Metal and the paravirtualised GPU infrastructure, you're stuck in console mode. And this has been just as much of an issue for virtualizing x86 macOS… although it does have a software rasterizer, it's almost unusably slow. The only way you're going to get decent performance with that is with passthrough of a GPU that macOS has drivers for (which for modern GPUs, means some Radeon 500 series, Radeon 5000/6000 series, or Intel iGPU up through Coffee Lake). Since the early 2000s, real Macs have practically never been configured in such a way that there's no usable GPU, and so the software rasterizer never got any attention since it's an absolute-last-resort fallback. With ARM Macs, all models have some form of usable GPU available (presumably, even the forthcoming M-series cheesegrater tower will have a few GPU cores in its SoC) and they don't care to support virtualization on anything but macOS so they dropped the rasterizer entirely.
