QtOpenCoreConfig VS WhateverGreen

Download & install OpenCore Auxiliary Tools - OCAT and launch the OCAuxiliaryTools application.

Used GitHub: OpenCore Auxiliary Tools (OCAT) to create initial config, while cross checking each setting with Dortania's OpenCore Install Guide

Please make a backup and use https://github.com/ic005k/QtOpenCoreConfig to update, it does all automatically

I use this: https://github.com/ic005k/QtOpenCoreConfig to update on each release , it automatically updates kexts ,drivers, opencore and the configuration but I always make a backup just in case

I would use this: https://github.com/ic005k/QtOpenCoreConfig

Here are the main ones I personally recommend as “must haves” when it comes to troubleshooting and building out your EFI, and getting things working: https://github.com/ic005k/QtOpenCoreConfig/releases/tag/20211217

But these OCS messages shouldn't have been there to begin with. I wanted to make them go away. How? Thankfully, I found ic005k's QtOpenCoreConfig, a pre-built app that inspects the config.plist and identifies errors in various Quirks & other config settings.

Try this tools https://github.com/ic005k/QtOpenCoreConfig Just two steps to upgrade your opencore to latest: open your oc config.plist, click save, then click sync oc It work well for me, hope it will for you

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.
