cloudstrife Posted January 14, 2022 Share Posted January 14, 2022 Hi! Im trying to passthrough a nvidia gpu to my MacOS High Sierra VM, but it only gives a black screen. Can anyone help me? I followed Spaceinvaders video several times but still no luck. I fixed the multifunction, added vbios etc, tried with and without topology, 3 and 4 cores (6/8 threads) I use the same GPU for a windows vm and a linux vm and it works perfect with the same settings (CPU pinning, RAM, vbios) Quote <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>Macinabox HighSierra</name>

ghost82 Posted January 15, 2022 Share Posted January 15, 2022 You need to install nvidia web drivers and enable them with a boot-arg (in opencore or clover). Boot arg is: nvda_drv_vrl=1 Quote Link to comment
