I'm don't think you can do GPU or PCI passthrough on macOS. Not sure if/when Apple would consider adding that.

I'm glad the things I want to do on Linux are all terminal based. I used a tiling WM for years on Arch and don't miss it much with all the macOS WM extensions available now (Magnet, Rectangle, Moom, Hammerspoon, etc). Less themeable but perfectly functional.

With Big Sur, Apple now has paravirtualization support. It exposes Metal API to manipulate virtual display devices. See https://developer.apple.com/documentation/paravirtualizedgra...

I doubt Apple has any intention of publishing hardware documentation for someone to write a native driver, but there are behavioral reverse engineering efforts already underway.

Very nice. An advantage of paravirtualization is that compositing across the guest and host will work, unlike passthrough. Any rough indication of the level of performance?
