Sorry for wasting your time RehabMan:
In the guide the kextcache needed to be rebuild for Audio:
Audio: After installing new/updated kexts or after the initial installation, you may lose audio.
To fix:
- reboot without caches (hit space at Clover, select without caches)
- rebuild cache
Code (Text):
sudo touch /System/Library/Extensions && sudo kextcache -u /
- reboot normally (if needed, two times)
But when trying to provide the Problem Reporting files and reading the Laptop Frequent Questions I stumbled upon this:
Q. How to install kexts?
There are various kext installers: Kext Beast, Kext Wizard, Kext Utility. I don't recommend any of them.
It is easy to install kexts with Terminal:
Code (Text):
sudo cp -R KextToInstall.kext /Library/Extensions
Or with older OS X (10.10.x and prior):
Code (Text):
sudo cp -R KextToInstall.kext /System/Library/Extensions
And to rebuild cache:
Code (Text):
sudo kextcache -i /
Or with older OS X:
Code (Text):
sudo touch /System/Library/Extensions && sudo kextcache -u /
So I did this
To fix:
- reboot without caches (hit space at Clover, select without caches)
- rebuild cache
Code (Text):
sudo kextcache -i /
- reboot normally (if needed, two times)
And the audio device appeared after reboot
Thx for your help
I learned a lot.
