@Patrick545 I haven't tried it lately.
You might try a newer version of the BrightnessKeys.kext
Copy over the existing one found in your EFI folder.
Update: The brightness keys (F11, F12) still work on BigSur 11.6
I updated to the lasted BrightnessKeys.kext; and (interestingly) an...
A complete guide is here
Though, I'd recommend starting with the OpenCore Configurator app. Use it to open the config.plist file. Explore around and see what's there. The only modification is to create a Serial Number and a System UUID. I chose MacBookPro14,1 as the desired model. See attached...
No. Clover's config.plist is structured very differently from OpenCore's config.plist. Actually, one should be very cautious in using a config.plist from previous version of OpenCore with new/recent versions, as modifications are imposed.
Make a backup copy of your EFI (Clover) folder, from the EFI/ESP partition. I'd recommend copying that to a USB stick and make sure you can boot from the USB stick for backup purposes.
Replace your EFI folder with the one from my previous post (Open Core). Use your own or create new Serial...
This guide has worked well for my RX570! Back in the Mojave days, I'd get GeekBench 5 Metal score of 43k. However, with Catalina and Big Sur, I was getting 27k. Now with the tweaks, I'm getting 44k. Nice!
Though, I still have a concern... It appears the idle power consumption is still high at...
Hello everyone! I'm a bit late to the party, as I've been learning more about OpenCore in preparation to update my laptop (Lenovo Ideapad S340-15IWL) to Big Sur. I'm ready to share my EFI for those who may be interested. From what I can tell, everything is working:

Hi all. FYI mine works with HDMI.
I believe in 10.15.4 there were changes in the framebuffer handling. Check your framebuffer patching, make sure your device-id is set to 0x3E9B0000
Also, be sure WhateverGreen is the latest version.
More/complete framebuffer patching would be this...
