barnum Posted June 14, 2016 Author Share Posted June 14, 2016 You mean the kext present in the 10.11.4 part? Because I already use it Regards Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 14, 2016 Moderators Share Posted June 14, 2016 do you have SIP disabled? did you run permission fix and rebuild cache? sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / Link to comment Share on other sites More sharing options...
MikeGiff Posted June 14, 2016 Share Posted June 14, 2016 Sorry to hijack the thread, but I have exactly this issue also. I do have SIP enabled, how do I disable this ? System Integrity Protection status: enabled (Custom Configuration). Configuration: Apple Internal: disabled Kext Signing: disabled Filesystem Protections: disabled Debugging Restrictions: enabled DTrace Restrictions: enabled NVRAM Protections: enabled This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

MikeGiff Posted June 14, 2016 Share Posted June 14, 2016 Thanks. I did this, re-did permissions and rebooted. The cache output was rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext IOAHCISerialATAPI_Injector.kext kext file:///Library/Extensions/DisableTurboBoostBattery.kext/ is in hash exception list, allowing to load kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext AppleHDAIDT.kext kext-dev-mode allowing invalid signature -67061 0xFFFFFFFFFFFEFA0B for kext IOGraphicsFamily.kext kextcache updated critical boot files, requesting launchd reboot The SIP is now System Integrity Protection status: disabled. However, still no audio. I should have mentioned it is a E6220. Anything else I can check? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 14, 2016 Administrators Share Posted June 14, 2016 The usual IDT patch simply applies https://osxlatitude.com/index.php?/topic/7914-dell-latitude-e6220-with-i5-2520m-hd3000-and-1366x768-lcd-mavericksyosemiteel-capitan/ You can simply apply the Vietnam tool patch to get audio going. It's listed for the E6x20. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 14, 2016 Moderators Share Posted June 14, 2016 @MikeGiff I"m assuming you're on Clover? and was working prior to upgrading? Boot without cache, repair permission and rebuild cache reboot in normal mode Link to comment Share on other sites More sharing options...
MikeGiff Posted June 14, 2016 Share Posted June 14, 2016 Hi Jake Lo No, sorry I haven't actually given you the full story! It was okay following the upgrade, but I had an issue where the volume would be on maximum each time I booted up, and when I clicked a volume button it would reset to the correct volume, halfway or wherever the slider bar indicated. So what I realised was that, even though I have a build from your instructions, using Clover, my kext arrangements were different to what you had in your boot pack. So I went ahead and installed your bootlick kexts. (6 into EFI Kexts Others) and 3 into LE. Looking at the difference in my old Kext - I seemed to be using the VoodooHDA in the EFI Clover. I tried with the boot without caches, rebuild and then reboot, but still the same. Thanks Mike Link to comment Share on other sites More sharing options...
