Hi, I have a HP EliteBook 9470m i7 laptop with OSX Catalina 10.15.7 with HD4000 at 1366x768 , everything works correctly except card reader and fingerprint reader. The problem I have is that when installing some applications the system loses the graphic acceleration at the next boot and the only way I have to solve it is reinstalling a system update. Does anyone know why this happens and how to fix it without reinstalling the system? Thanks and apologies for my English, it is not my native language.
It was enough to apply:
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 /
Reboot and running
Thank you all for your answers
