Lordadmiral Drake Posted January 7, 2014 Share Posted January 7, 2014 I downloaded a patched AppleHDA.kext for my sound codec. But it won't load. When I try to load it manually with kextutil I get the error: Code signing failure: Code signature is invalid Link to comment https://www.insanelymac.com/forum/topic/295133-cant-get-applehda-to-load/ Share on other sites More sharing options...
slayer2333 Posted January 7, 2014 Share Posted January 7, 2014 Did you try to boot without caches after you installed your kext and repaired permissions ?

Lordadmiral Drake Posted January 7, 2014 Author Share Posted January 7, 2014 No. I installed the kext using Kext Wizard and then did "Rebuild System Kext Cache" I didn't do repair permissions because AFAIK kext Wizard does that during kext installation Link to comment https://www.insanelymac.com/forum/topic/295133-cant-get-applehda-to-load/#findComment-1982842 Share on other sites More sharing options...
slayer2333 Posted January 7, 2014 Share Posted January 7, 2014 Ok, but what i mean is that for some reason, some configurations (like mine) won't load AppleHDA when using Cache at boot. You may try with nocaches in clover or -f in chameleon to see if it still doesn't load. If so, you may double check your AppleHDA patch.

Allan Posted January 8, 2014 Share Posted January 8, 2014 try this: sudo touch /System/Library/Extensions after this, shut down, don't restart, and wait 10 sec, and start. looks funny, but it worked for me. Thanks Mirone by that. Link to comment https://www.insanelymac.com/forum/topic/295133-cant-get-applehda-to-load/#findComment-1982954 Share on other sites More sharing options...
Lordadmiral Drake Posted January 12, 2014 Author Share Posted January 12, 2014 Booting ignoring caches did the trick for me. But is there a way to get the kext to load even if I don't do that?

Let me know if you find out how to load AppleHDA using Caches. Tried deleting caches and rebuilding with: KextWizard/Kext Utility/Pandora/Manually from terminal/ but nothing worked for me, everything loads except audio.
