Hi,

I am trying to passthrough FirePro D700 gpu to MacOS Catalina VM in ESXi running on MacPro6,1.

I have tried normal MacOS VM with ESXi it didn't work. After deep inspection and research I found out that ESXi doesn't provide the VBIOS to MacOS VM and hence no way of MacOS to read information about the GPUs.

After researching more I found out that with SSDT i could inject VBIOS via "ATY,bin_image" property. I extracted VBIOS with DarwinDumper and created SSDT. I installed OpenCore to add this SSDT and enabled WhateverGreen and Lilu. Now IORegistry shows that I have bios for my GPU but still there is no output on any of my ports.

I am trying to inject more properties but no luck.

I have attached my OpenCore folder below.

Has anyone ever attempted something similar? Any help or pointers how can I implement this?

PS : Just to let you know I can make this work with Proxmox as it allows an option to inject GPU vbios but need ESXi for compatibility purposes.

while I don’t have the answer to PCIe pass through for esxi
I do have some questions ...
is ESXi booting in EFI or BIOS CSM mode?
what benefit do you get from using a VM of Catalina on the trash can vs running natively?

ESXi is booting in EFI mode.

Booting VM enables testing with multiple configurations much easier for my development projects. I could boot any VM quickly for needed configuration.

someone can correct me, but assuming you're doing it so a guest OS can have a separate, dedicated GPU to that used by the Host OS, the 2013 handles all its display duty from only one of its GPUs, the other is a compute accelerator, and not plumbed in to the TB / DP bus.

Perhaps that is at the root of your problem?

Hi there, I recently found the answer, here. I have already solved it, use opencore to guide, and then use the vbiso to load the graphics card to drive the graphics card. hope this helps
