For some reason I keep getting the following error: System extension cannot be used.. The system extension "/S/L/E/ACPIBattery.kext" was installed improperly and cannot be used: Please try reinstalling it, or contact the product's vendor for an update. I tried reinstalling it but it comes up everytime. How do I fix this problem?
