Hi,

I installed Mac os Big Sur 11.2.2 on my Hackintosh, I use Open Core 0.6.7, I follow the amazing install guide from OpenCore. Succees for me with my config :

Processor :Intel Core i9 10850K 3.60 GHz

Motherboard :MPG Z490 GAMING CARBON WIFI (MS-7C73) 1.0

ChipsetPont nord : Intel Comet LakePont sud : Intel Z490

Memory : 32 Go

Graphics Card :NVIDIA GeForce GTX 1050 Ti

But as you can see I have a GPU who doens't work with Big Sur, in the futur I will buy a last AMD graphics card like AMD RX 6XXX xt who should work with Big Sur and futher versions.

In the meantime I would like to use the Internal Graphics of the processor. But I only managed to boot with my external GPU (see screenshot) :

Boot with GPU but only 8Mo graphics


So on Windows I will use the PEG card and on Macos the IGD.

But I have a black screen when I try to boot with option IGD (with HDMI port on the motherboard)

My USB with OpenCore :

Boot args : alcid=1 igfxrpsc=1 igfxonln=1

My config.plist in attachement :)


I thinks I miss something in config.plist or some kexts, have you a idea?

Thanks

Hi,

any ideas for that ??
 
Hi, did you manage to solve the issue? I own a similar configuration and can't get the UHD 630 Gpu to work
i tried different frame buffers and googled for a gazillion years and found multiple cases of people failing to succeed with UHD 630 on Big Sur.
 
You have to boot into dvi and then do the mapping of the video outputs
