• I'm not responsible for any harm done to your PC :-) Use my experiences and EFI at your own risk, even though I think this doesn't do much harm ;-).

Make sure (!) you are using the latest kexts:

• FakeSMC.kext https://bitbucket.org/RehabMan/os-x-fakesmc-kozlek/downloads/
• USBInjectAll.kext https://bitbucket.org/RehabMan/os-x-usb-inject-all/downloads/
• Lilu.kext https://github.com/acidanthera/Lilu/releases
• WhateverGreen.kext https://github.com/acidanthera/WhateverGreen/releases

For convenvience purposes, use either OpenCore Configurator or Hackintool to mount EFI and update the Kexts.

So far Big Sur with OpenCore is working very well. A small how-to here:

PRECAUSION:

• Currently using Big Sur Public Beta.

• I'm using OpenCore 0.6.2. You can download the latest build from here which you can use during the EFI creation as per below: https://github.com/acidanthera/OpenCorePkg/releases

• Also great info from: https://dortania.github.io/OpenCore-Install-Guide/extras/big-sur/#backstory

• USB preparation and installation of Big Sur according this video: https://www.youtube.com/watch?v=J22vqnS-QZ4&t=2s

• Create your EFI: https://www.youtube.com/watch?v=XyDJMNMFi6I&t=58s

• When the EFI is done, add your SSDT's and DTSD's to the EFI partition using OpenCoreConfigurator to mount the EFI

• After that, create your own Serial Number using OpenCoreConfigurator

You need to make your own serial number, so that your iCloud etc. will work without using someone else his serial number.

• In general; watch others do first to see if they succeed:
• Make sure first to install the latest Kext files
• Install latest OpenCore; but first make sure that this works according other users. Latest OpenCore build: https://github.com/acidanthera/OpenCorePkg/releases
