If AppleHDA doesn't work, then use VoodooHDA. It works best for my PC and my laptop

Here you go!
OC-0.6.3 working EFI for Big Sur. This is a slight modified version of @Mikorist 's one.

• You have to fill PlatformInfo section by yourself
• UpdateSMBIOSMode is set to "Custom" and Kernel->Quirks->CustomSMBIOSGuid is set to true: this won't pass SSDTs to other OSes and you'll be able to boot Windows/Linux "natively" from OC. Breaks BootCamp
• OpenCanopy is enabled but you need to fill OC/Resources subfolders
• Should work with Catalina too

I am working on a new EFI with some custom SSDT, proper USB mapping, VoodooPS2 (Enables touchpad gestures for me) and AppleALC (microphone issues atm). I am facing sleep issues, so I won't share it yet.
@Mikorist if you want to help me improve the EFI, send me a PM.

Very good work! Is there an installguide from Mojave to Big Sur? Any News for an Update of the EFI? Thanks for your help.

1. Create a bootable USB using my EFI and verify it can boot you Mojave installation. Remember to fill the SMBIOS section with the same data you have in your actual Clover/OC config.plist (Disconnect from iCloud and/or any network until you are sure the SMBIOS is properly set)
2. If Mojave boots fine (and SMBIOS is ok) you can put the EFI on your HDD/SSD
3. Backup your data
4. Update to Catalina (maybe optional) using Preferences->Software Update
5. Update to Big Sur using Preferences->Software Update
6. Enjoy

Hi folks

Like daigosx I've got my Z50-70 working with Big Sur OpenCore 0.6.3 using Mikorist's EFI as the base (big thanks to Mikorist). Everything appears to work including sleep/wake, battery/power management and FaceTime/iMessage.

My machine still has the original AR9565 wifi card which only has limited OS X support, I used to have it working in High Sierra but am still working on it in Big Sur. If someone has a solution to this please post it!

Cheers
Benny Hedge

I'm having problem after update from 10.15.7 to 11.0

In same SSD I'm using 11.0 which was clean installation. It is working fine. But when I tried to update my existing Catelina partition, I'm getting error.

Both partitions are being loaded from same SSD's EFI.

Here is my EFI without resource directory
