Hello @FlyinBurritoMan,Hello Casey and all,
...
With that in mind, does any one have success with installing an unsupported GPU in slot 1 for windows, yet use the Hackintosh in headless mode? I realize that I'd lose my GPU acceleration (how I wish Apple and Nvidia would make up and play nice!). I have access to a Vega 56 that I could use from my older Hack (i7 4790k machine) if needed, though I'd like to keep it in my older system.
...
Update: I think I figured out how to boot into my Hackintosh in headless mode/using the iGPU. I removed the GPU from the computer, made a copy of my config file, updated it to match the "config-internal-GPU.plist" from "Mini-Guide for Fresh Installation of Catalina 10.15.1 and Newer" files since those were the files I originally used (and am still on).
I was not able to use the HDMI port on the motherboard to display video on my Hackintosh (though it works in the BIOS), but using Thunderbolt to DP adaptors work fine in Hackintosh.
Now to install the 3090 and see what happens on the Hackintosh side. Will be looking into how to disable Slot 1 soon. Wish me luck!
Unfortunately it's an all-or-nothing proposition with unsupported GPUs. As you pointed out, GPUs serve two purposes:
- Driving a display monitor via HDMI, DisplayPort, and other connectors.
- Providing immense "compute" power for specific classes of functions.
- Headless mode: iGPU provides compute power to specific applications, but does not drive a display monitor.
- Non-headless mode: iGPU provides both compute power and ability to drive a display monitor.
- Disable the GPU entirely via an SSDT (this completely hides the GPU from macOS).
- Use the GPU to drive a display monitor over HDMI, DisplayPort, etc. but without display acceleration. This means windows will move slowly, windows will scroll even more slowly, etc. Everything that appears on screen will appear and move very slowly.
