Recommended Posts

Hi guys
I want to install Big Sur on my device, but we know that Nvidia support has stopped on new versions of Mac after 10.3.6
I'm hoping for help Can I use IGPU 630 and do a dual boot as I use Windows with 3080 RTX and use MacOS on intel UHD630
And if it is possible and there is a way, what are the Bois settings on MB and what is the use of the optimum EFI
Please provide any help regarding this and thank you

Please complete your signature (user > profile).

Do you already have an EFI that boots macOS on your PC? Just ask how to configure it so that Windows uses the Nvidia and macOS uses the Intel iGPU?

Well
please  help 
Unfortunately I don't have it. I'm looking for a file that is ready to work because I tried a lot of it that freezes on the Apple logo and restarts
I hope to get something. I have an attached file. I think it needs to add an Intel driver in order for it to boot. Is it possible to look at it and help me?

 complated done .. please help

To have 2 graphics cards and use one with Windows and the other with macOS, you have to:

  • connect 1 cable to the monitor from each GPU (2 x HDMI or one HDMI and one DisplayPort) to avoid changing the cable from one GPU to another when changing systems
  • disable the GPU you don't want to use in Windows
  • disable the GPU you don't want to use on macOS.

I don't know how to disable a GPU in Windows but to do it in macOS there are sites with instructions.

 

Disabling desktops unsupported GPUs (SSDT-GPU-DISABLE)

 

Option 2: Blocking discrete GPUs from MacOS

 

The easiest way to do this is with WhateverGreen's disable-gpu switch. You have to know the PCI path to the GPU that you want to disable. For example, if it's PciRoot(0x0)/Pci(0x2,0x0) DeviceProperties looks like this:

Thank you for the help and attention I did it in Windows
But the second method on the Mac, I do not understand it or do it
Can you help me in installing and configuring a EFI file that deals with my PC I hope for help. I know that I make many requests, but I trust you. Thank you, brother.

In ACPi folder there is a SSDT-RX 5700 XT-Version 1.0.aml file. Do you have a RX 5700 plugged into your machine?

In ACPi folder there is SSDT-UIAC.aml and in Kexts folder there is USBMap.kext> is it an USB ports map specific for your mother board?

In Kexts folder there is DAGPM.kext> it's not useful for Intel iGPUs.

What device is PciRoot(0x0)/Pci(0x1b,0x0) located at DeviceProperties with a layout-id = 05000000?

agdpmod=pikera in boot-args is for RX 5700 card.

 

Question: do you want to use Intel iGPU with macOS as single card? Disabling GeForce RTX 3080?

 

I'll do changes in config.plist after reading your answers.

Yes, I want to use an intel VGA card in a macOS
And if I need use a 3080 card on a Windows gaming system
Please help, I know I'm tired of you because of my problems :)

@GEMY

This is your EFI with changes:

  • SSDT-RX 5700 XT-Version 1.0.aml removed
  • DAGPM.kext removed
  • device PciRoot(0x0)/Pci(0x1b,0x0) located at DeviceProperties with layout-id=05000000 removed
  • added properties for iGPU in device PciRoot(0x0)/Pci(0x2,0x0)
  • added boot-args: igfxonln=1 -disablegfxfirmware -wegnoegpu, the first 2 for the iGPU to be the main card and the third to disable dGPU
  • modified USBMap.kext, it was set for iMac19.1 but you are using iMac19.2.

Try and comment. If this EFI doesn't work, I don't have anything else for you.

Note: at first boot with a new EFI, always do ResetNVRAM.

Note: it's to be used with iGPU as main card in BIOS and cable from iGPU to display.
