Thank you for the detailed explanation.

I meant where in the config.plist does the choice of the correct Airportltlwm.kext executed. Both Airportltlwm.kext are enabled.

I follow Dortania’s install guide, was able to make wifi work but not Bluetooth. With your EFI both wifi and bt work. I’m not able to identify how you can make bt work fron your config.plist. Can you explain your approach to enable bt?

I was not able to use ProperTree to do a “OC Clean Snapshot” of the OC folder. Wonder how the config.plist was created. How’s the dual boot done?

Don’t understand why need to include both Airportltlwm_BS.kext and Airportltlwm_Monterey.kext.

Try to remove one of them and it doesn’t boot.

Tried to install Big Sur with opencore 0.69 on GA-H77N-Wifi.

installation proceeded almost to the end but stuck before the setup screen appears and voiceover took over.

Can hear the voiceover instructions but no screen shown, can turn off voiceover with keystrokes.

EFI attached.

Upgraded to 0.68 and apply the following patch to get the DVI and HDMI ports working properly. Still trying to make the VGA port work...

 

framebuffer-patch-enable = 01000000

framebuffer-con1-enable = 01000000

framebuffer-con1-type = 00080000

I did add those 3 lines with values according to Dortania, but same colour distortion. If I use the incorrect platform ID and get the correct colour the display info is incorrect. The 24” dell monitor cannot be identified and interpreted as a 31.5” display

@Jake Lo When I accidentally reversed the number to 00005916 I got the correct colour. But if I used correct platform ID, I got the distorted colour as shown in the first post. The second config.plist attached is the one I got the distorted colour but IOReg results did show correct display info.

@Jake Lo Actually I attached the wrong config.plist file. The one attached above gives the correct color but the one that I attach here with the correct platform gives the wrong color. The IOReg for the display is incorrect and cannot identify the correct display device.

@Bronxteck I tried that but no effect. One strange thing is that if I use screenshot to save the screen the resulting image gives correct color.

Hello, 

My system uses Gigabyte GA-Z170-hd3 with Core i7-7700 with processor graphics HD630.

It boots and installed but the color is distorted as shown in attachment. 

Any help would be appreciated.
