Lenovo-ThinkPad-X1C7-OC-Hackintosh VS WhateverGreen

Search for GitHub pages with laptops similar to yours. I found this page and it was very helpful for me.

For reference, I am using a Thinkpad X1 Carbon Generation 7. My CPU is i7-10510u and it is ambiguous whether my GPU is UHD 630 or 620. I used some of the kexts and ACPIs from this source but I made the config.plist myself. I also used the Dortania guide throughout this process. My EFI folder is here.

I have the same laptop running BigSur 11.2.3 github repo. I never got the mic to work. I either plugged in headphones (with a mic) or used a small USB mic. I'm planning to update OpenCore and MacOS next week. Let me know if you manage to get the mic working please.

You can try my repo. There are others as well on GitHub.

And finally, one last fix i needed to make all 3 screen working (before only 1 was working), was to replace the kexts with the newest version: https://github.com/acidanthera/WhateverGreen/releases

(from https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md)

Intel HD 520 graphics - WhateverGreen, AAPL,ig-platform-id = 00001B59 , device-id = 16590000

If so, refer yourself to Intel iGPU Patching guide and WhateverGreen patching manual.

I went to this site from the dortania opencore guide https://github.com/acidanthera/WhateverGreen/releases And I downloaded the 1.5.9 version I copy the kext file and I replace the old file with the new one in the kext folder.I have an amd gpu but I think there is hope.

Only other things I would check would be the BIOS settings. Otherwise you may need to work through the Frame buffer patching guide

Check this, there is more information about patching with whatevergreen.
