You didn't put the slot values nor framebuffer values.

FYI my settings look like this:

Try in boot-args with:

-v keepsyms=1 debug=0x100 alcid=7 -igfxmetal=1 -wegnoegpu

Set SecureBoot to disabled and enable IGPU in BIOS.

If you still have issues try my latest EFI here https://www.tonymacx86.com/threads/...-core-i5-10400-nvidia-gtx-1060.310287/page-15

I tried, the GPU was not initialized.

Use my latest EFI then. It should work with 11.4. And make sure your BIOS settings are what I’ve stated in my guide.

If you still have issues, I’d suggest that you remove the Nvidia card and just try booting with Intel IGPU on its own (just to remove any hardware issues stopping the booting). If you boot with the Intel only you should only need -v alcid=7 in the boot-arg and make sure the AAPL,ig-platform-is 00009BC5.
