rahuliyer95 Posted March 24, 2015 Share Posted March 24, 2015 Hello, I wanted to remove the NullCPUPowerManagement and use AppleIntelCPUPowerManagement for my Lenovo Y510p haswell laptop. I deleted the kext from /S/L/E and rebuilded the kext cache using kext wizard, on reboot kextstat shows NullCPUPowerManagement is loaded. Please help on how to fix this I am using Clover boot loader Link to comment Share on other sites More sharing options...

styrian Posted March 24, 2015 Share Posted March 24, 2015 Hello! Use Spotlight to find it´s location. Perhaps it is part of an universal garbage kext. If it is not anymore installed, boot by ignoring caches. Have fun. Link to comment Share on other sites More sharing options...

rahuliyer95 Posted March 25, 2015 Author Share Posted March 25, 2015 Hello! Search with Spotlight for nullcpu.....kext. Have fun. Already did that no search results found Link to comment Share on other sites More sharing options...
styrian Posted March 25, 2015 Share Posted March 25, 2015 Hello! Look for non Apple branded kexts and show their content. I don´t use distros. Perhaps Niresh is installing an universal (garbage) one. Have fun. Link to comment Share on other sites More sharing options...

jamiethemorris Posted March 26, 2015 Share Posted March 26, 2015 Is it possible you didn't actually clear the cache completely? Run kext utility (specifically) to be sure... Also... Perhaps it's loading it from /Library/Extensions? Spotlight won't always show everything for some reason. Also it's possible Niresh came with some universal kext with kexts inside of it as plugins (sort of like older versions of MyHack came with MyHack.kext). EDIT: Sorry, I didn't see your update that you did a new install. 1 Link to comment Share on other sites More sharing options...
