Thank you so much !!! I now have audio and USB working, i'm so grateful for your help with this. One minor issue is that with these files, when I first boot up the laptop seems to go to sleep and every now and again it will just auto sleep. I'm happy to live with this for the time being though. Thanks again for your continued help.

I've tried 12 with no success. Just don't understand what i'm missing. You mentioned no need to use the kext patches in cover since i'm using AppleALC.kext. If this the preferred way of doing this, or would you normally suggest using the kext patches in cover and no AppleALC.

Done and still no audio. Really not having much luck with this... I have booted in Windows on this laptop just to confirm audio and USB still work. Attached is latest debug info. To confirm, what layout ID should I be using ? Thanks again debug_31518.zip

Thanks for your continued help with this. Apologies for not replying sooner, I have been away on business. I have tried restoring vanilla AppleHDA and removing the hotpatch etc and still no audio debug_18889.zip

Thanks Jake Lo. Hopefully I have done this right. computer_debug.zip

Apologies, that was because I was just trying all the different patches as a last resort. I have now enabled and disabled the relevant patches as below, but still no sound or USB.

I started with just the files from the Optimus ZIP file a few pages back. There were only 2 files from that to go in /L/E after I repaired permissions and rebuilt cache. AppleBacklightInjector.kext DisableTurboBoostBattery.kext No output device is detected in OS X. I then tried copying over the old files I used for 10.12 and added the ACPI patch for HDEF (I'm not sure if needed but was in my old config.plist), again no output device. I've since played around with different KEXT's and config.plist's but can't get any output device to show. I've now taken my OS X install back to stock AppleHDA.kext, repaired permissions etc and just using the files from Optimus.zip. What is the best way for me to get audio working from stock ? With regards to USB, I've applied the patches and deleted GenericUSBXHCI from my EFI partition, but again only the corner USB port is recognised. Here are my ACPI patches and Kernel Patches Thanks again.

Thanks to everyone in this thread, I've managed to get 10.13 finally installed on my E6530. I had to use the Optimus boot pack (as I have the NVIDIA520M Discrete) to disable the NVIDIA and just use the Intel HD4000, but I can't get sound or the USB ports working. I previously had sound and the USB ports working in 10.12 and have even tried using the same Kexts and Clover ACPI patches but no sound card is detected in OS X or the USB ports work (Apart from the rear corner) Do I need newer versions of previous APPLEHDA/IDT and GenericUSBXHCI kext files, or should just files from the Optimus pack work ? Thanks.
