Hello peoples,

maybe I am in the wrong forum but I am frustrating about using a RX 6600 XT on a MacOS Sequoia. I can passthrough the GPU and I can start the boot of macOS where I will see the gray Apple logo boot screen but right after the loading bar processes the screen turns black and the VM hangs. I am using https://github.com/luchina-gabriel/OSX-PROXMOX to setup the VM and tried different variations of `-v debug=0x100 keepsyms=1 agdpmod=pikera` as args to make the GPU work. May config look

```yaml
# Hackintosh VM - Sequoia
