Remove VoodooHDA, replace content into /EFI/Clover

Kexts in /EFI/Clover/kexts/Other/CopytoLE goes into /Library/Extensions

Repair permissions and rebuild cache

 

M6800_HS.zip

internal sound works good thx a lot :<3 

 

but when i connect headphone just play noise... and in sound preferences the only output is internal speakers..

Try this for USB3

The patches I add for Brightness is for Intel HD Graphics only, won't work on Nvidia.

You could try Brightness Slider app

As for headphone, looks like it's not automatically switching. Try closing and removing the lid with the headphone plug in

config.plist.zip

 

no the USB3 not work too :(
