Boot without cache and then run this again and reboot.

      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 /

You forgot to update the files from the Update section.

Replace AppleHDA_ALC255.kext from the update section to /Library/Extension and run the fixes again.

Audio should work then.

Is the keyboard working now?

[victor27rs]

well remembered'll update this kext ..

The keyboard, touchpad and battery still does not work

 

[victor27rs]

now the audio is working! Thank you!

All that's missing: battery, keyboard and touchpad ...

The kexts EFI folder I have to put them in the L / E?

[Jake Lo]

So I'm assuming you're using an external mouse and keyboard then?

Do you have the voodoops2controller.kext in /EFI/Clover/Kexts/Other?

 

Only need to have kext in Other/LE in /Library/Extension.

The rest in Other can run from there.
