All - I spent several days trying to figure out how to rebuild the kernel cache since upgrading to Catalina. I finally found the information hidden in another thread. I am hoping this information will help others.
To Rebuild Kernel Cache & Fix Permissions then restart.
"I forgot to mention that since Catalina now moved macOS main file system to read-only mode you first need to run these commands in the Terminal to
Disable Gatekeeper and mount file system in read/write mode:
Code:
sudo spctl --master-disable
sudo mount -uw /
sudo killall Finder
Repair permissions & rebuild kernel cache:
Code:
sudo chown -v -R root:wheel /System/Library/Extensions
sudo touch /System/Library/Extensions
sudo chmod -v -R 755 /Library/Extensions
sudo chown -v -R root:wheel /Library/Extensions
sudo touch /Library/Extensions
sudo kextcache -i /
Alternatively you can use Hackintool which does this among other things: Hackintool read this guide"
