kext VS WhateverGreen

do you have both USBToolBox.kext and UTBMap.kext? you need both USBToolBox.kext and UTBMap.kext for USBToolBox to function. https://github.com/USBToolBox/tool https://github.com/USBToolBox/kext

https://github.com/USBToolBox/toolhttps://github.com/USBToolBox/kext

Output from usb mapping is UTBMap.kext. Then you add USBToolbox.kext

If you have access to windows, this is a good usb mapping script. https://github.com/USBToolBox/kext. Heaps of guides around.

USBtoolbox, UTBmap

Do the usb mapping with USBToolboxadd Toolbox.kext too

Next, head here (https://github.com/USBToolBox/kext/releases)

Before you install OSX on the target machine, install Windows 10 or Windows 11 first. Make sure that ALL of your drivers for Windows 10 or 11 are installed (especially your chipset drivers). Use the Windows version of USBToolBox, and map your ports per their instructions (basic instructions are on the same page with the utility). Grab that here: https://github.com/USBToolBox/tool. Run the Windows.exe version (your antivirus software will go nuts trying to run this on your machine, either allow it, or rename the executable after unpacking it). Copy the created kext (called UTBMap.kext) file this program creates onto a separate flash drive to use after MacOSX is installed. Next, head here (https://github.com/USBToolBox/kext/releases), and grab the two kexts (USBToolBox.kext and UTBDefault.kext) within the zip file. Unpack, and put them in your EFI/OC/Kexts folder on your bootable USB drive. Use ProperTree to open the config.plist on your bootable drive, do an OC Clean Snapshot (this updates the config.plist with the new kexts you added), and SAVE.

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.
