Hi again still have problem with audio and GPU work...Pupilliam is not respone for my PM

Re: audio, you'll have that working if you follow the same process as for any Latitude E6x20 laptops. They have same IDT 92HD90 codec. But since you've not bothered to provide any details of your installation, we can't guess whether you'll need patched AppleHDA kext for Enoch or on-the-fly patches for Clover. Anyway, if you search the forum, you'll find what you need.

 

Same for GPU, we don't know whether you use integrated HD3000 or discrete nVidia Quadro 4000M with Optimus disabled.

I am using discrete Quadro 4000m, Optimus disabled.

 

Here is my EFI folder:

A few things to correct in your Config.plist:

1. in ACPI section, remove P States & C States generation, that's for C2D, C2Q and 1st gen "i" Core (like Arrandale) CPUs.
2. in Kernel & Kext Patches, remove KernelPm patch, that's for Haswell and later platforms; AsusAICPUPM is all you need for your SandyBridge platform (keep AppleRTC patch).
3. In Kernel & Kext patches, what are all those AppleGraphicsDevice Policy patches?
4. In Kernel & Kext patches, do you really need the USBXHCI patch? Do you intend to add USB hubs that would increase your USB ports beyond 15?
5. In Kernel & Kext Patches, simply add the required 3 x AppleHDA patches:
   • replace 8419D411 by 00000000 (2 x instances if you manually patch the kext)
   • replace 8A19D411 by 00000000 (2 x instances if you manually patch the kext )
   • replace 8B19D411 by E7761D11 (2 x instances if you manually patch the kext)

• Then add the dummy kext for IDT92HD90  to /Library/Extensions, repair permissions and rebuild your cache. That'll give you full audio.

sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo touch -f /L*/E*
sudo kextcache -Boot -U /

For native CPU SpeedStep, you need to generate your CPU-specific power management  SSDT though Pike R Alpha's well-known generator script.

You've not bothered to apply any of the changes suggested in post #7.

I do not know how to set it up, guys from another forum sugested me to use this clover folder that I've uploaded here. But booting OSX without NullCPUPowerManagement.kext isn't possible. I am caual Windows user wanted to learn Final Cut
