Introduction
How to disable your unsupported GPU for macOS
So you got your shiny new RTX 2080ti BLOWYMATRON edition but you've probably noticed there's currently no support for your GPU in MacOS Mojave. Well for those who are running Maxwell, Pascal or Turing GPUs there is still some hope for you with options to spare!
This is an information thread, for discussion please visit the r/hackintosh thread: How to disable your unsupported GPU for macOS
Prerequisite
- A Hackintosh built off the Vanilla guide(This is a must as you need to have a clean system for this to work properly)
- A GPU that is support in Mojave/Catalina(generally this will be an iGPU for most users here, check the GPU Buyers Guide to see if your GPU is supported. Keep in mind that using a Kepler GPU with Maxwell, Pascal or Turing GPUs will require more work)
- A Plist editor: Clover configurator works fine
BIOS Settings
For those planning on using an iGPU, make sure to have the following enabled in your BIOS:
- iGPU Multi-Monitor: Enabled
- Primary Display: Enabled
And make sure to have your displays connected to the motherboards display outs
Can I use the iGPU for rendering but the video outs of my dGPU?
Unfortunately not, and the reason being is actually quite similar to how Nvidia's Optimus technology functions. You would first need a way to grab/encode the iGPU's signal, send it towards the discrete GPU, then have said GPU decode the signal and display it. One small problem, decoding the signal would require proper GPU acceleration which your unsupported GPU doesn't have. So you will need to use your motherboard's video out ports no matter what
Which Options should I choose?
Option 1:
- Disables all GPUs that aren't the iGPU
- Quick and easy with little work, avoid when possible as it doesn't always work
Option 2:
- Disables all GPUs from one brand(ie: all Nvidia GPUs)
- Only usable for Clover, Opencore users must use either options 1,3 or 4
Option 3:
- Disables a specific GPU
- Recommended for those who run Kepler GPUs with Maxwell, Pascal or Turing
Option 4:
- Disables on a per slot basis
- Recommended for those who run Kepler GPUs with Maxwell, Pascal or Turing
OpenCore Users
For those running OpenCore, I highly recommend reading the Disabling GPU Guide found in the OpenCore guide as this has specific OSI fixes for SSDTs
