Hi all, First of all thanks Jake Lo for the great guide ! I installed following your guide https://osxlatitude.com/index.php?/topic/5641-dell-latitude-e6430-e6230-intel-mavericks/ My system is Dell E6530, i7-3540, HD4000, 1920x1080 My current version is Mavericks 10.9.3, I upgraded from 10.9.2 My problem is that I do not have sound working at all and I am using the latest AppleHDA you provided, Apple HDA provided for 10.9.2 also doesn't work (it didn't for 10.9.2 either) These are the lines containing AppleHDA from system.log Jun 15 12:03:06 Cristians-MacBook-Pro.local com.apple.kextd[12]: WARNING - Invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext "/System/Library/Extensions/myHack.kext/Contents/PlugIns/AppleHDAController.kext" Jun 15 12:03:06 Cristians-MacBook-Pro.local com.apple.kextd[12]: WARNING - Invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext "/System/Library/Extensions/myHack.kext/Contents/PlugIns/AppleHDA.kext" Jun 15 12:03:07 Cristians-MacBook-Pro.local com.apple.kextd[12]: WARNING - Invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext "/System/Library/Extensions/myHack.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext" Jun 15 12:03:08 Cristians-MacBook-Pro kernel[0]: Sound assertion in AppleHDADriver at line 1535 Jun 15 12:03:08 Cristians-MacBook-Pro kernel[0]: Sound assertion in AppleHDADriver at line 2205 Jun 15 12:03:08 Cristians-MacBook-Pro kernel[0]: Sound assertion in AppleHDADriver at line 207 Jun 15 12:03:08 Cristians-MacBook-Pro kernel[0]: Sound assertion in AppleHDADriver at line 1094 I assume the first 3 warnings are ok but the next lines are not Any help is greatly appreciated !

Sorry but I don't remember, it was a week when I tried everything I could find so everything is a little blended together

Hi, I had the same problem with hanging and at some point just restarting when loading the graphics driver (Dell E6530, i7-3540M, HD4000) I've tried with Chameleon, Clover and Niresh image Then I tried installing Windows 7 and I noticed the the graphics driver was refusing to install This led me to the conclusion that there is a hardware problem so I tried on another identical laptop and it worked
