(Optional - See Note) Update to the latest Clover
See the tonymacx86 Clover Builds (in Download menu) to update Clover.
Starting in February 2020, Apple will "clamp down" on non Apple approved kexts. So, update Lilu, WhatEverGreen and AppleALC, placing them in your /EFI/.../Clover/kexts/other/. Remove these kexts from the /Library/Extensions/ folder. If you haven't already, move any other hackintosh kexts from /Library/Extensions/ folder to the .../Clover/kexts/other/ folder. Then run the following Terminal command to rebuild the macOS cache:
Code:
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches
