Liquid007 Posted January 8, 2021 Share Posted January 8, 2021 Hi all So I had a working version of High Sierra installed on my Dell Latitude E7440. It was working fine with no issues and was a dream to use on my Latitude E7440. Until two days ago, the audio stopped working. Now I had this before on a Sierra build, and the fix was simple to use a kext installer utility to reinstall the AppleHDA.kext reboot the system and the audio would work again. So thats what I did, fired up the Kext Utility installer, dropped in the AppleHDA out of the E7440_HS file pack and rebooted the system. On reboot, I had the No Entry logo come up. So rebooting again and adding -v to see the error. Error comes up as Error Loading Kernel Cache (0x1b) I don't really want to reinstall the whole system again so is there any way I can fix this and get High Sierra working again. Any help appreciated here, many thanks Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 8, 2021 Moderators Share Posted January 8, 2021 Why would you install AppleHDA.kext, where did it come from? Try bootarg UseKernelCache=No Link to comment Share on other sites More sharing options...
Liquid007 Posted January 8, 2021 Author Share Posted January 8, 2021 Thanks for replying Jake Lo. In hindsight it was stupid of me to add that kext. the kext is AppleHDA_ALC292.kext I could have sworn it was the right kext to use to fix the audio that I had used in a past sierra build when this happened to me before, but as it was long ago i couldnt be sure. Added UseKernelCache=No to the boot argument in Clover and tried to boot but came up with the no entry sign again Am I doing something wrong here?

Administrators Hervé Posted January 8, 2021 Administrators Share Posted January 8, 2021 Afaik, you can no longer boot Clover without cache. I expect you'l have to resort to boot in single-use mode to remove your offending kext(s) and manually rebuild your cache with the usual commands (see FAQ section).

Liquid007 Posted January 8, 2021 Author Share Posted January 8, 2021 Thank you for your reply Herve, Sorry to ask but could I ask how I get into Single-User Mode from the clover boot menu using a Windows based keyboard . Sorry that you have to deal with this idiot Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 8, 2021 Administrators Share Posted January 8, 2021 Indeed, you could try and learn some of the basics of Clover... When at Clover main menu, select your target partition and press [SPACE]. Then use the menu option. Link to comment Share on other sites More sharing options...
