Hello,

 

I have problem with my wifi after update from Catalina. :-(

 

Previously I copied kext to Library/Extensions and did command belowand it worked.

sudo spctl --master-disable
sudo mount -uw /           
sudo killall Finder  


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 /   

 

But now it ends with this

mount_apfs: volume could not be mounted: Permission denied
mount: / failed with 66

 

Please help.
