Administrators Hervé Posted February 28, 2017 Administrators Share Posted February 28, 2017 No apparent native CPU PM in placed at all... I would not expect you need to select/activate "Drop OEM" in the ACPI->SSDT section of your Config.plist. Double check for any rogue NullCPUPM kext left over in /L/E or /S/L/E. If found, delete the kext and rebuild your cache. Link to comment Share on other sites More sharing options...
npyadav1 Posted February 28, 2017 Author Share Posted February 28, 2017 I found only two Kext files like NullCPUPM kext fils in /S/L/E. 1. AppleIntelCPUPowerManagement.kext 2. AppleIntelCPUPowerManagementClient.kext Link to comment Share on other sites More sharing options...
