Recommended Posts

I have updated my laptop on high sierra.

Since i have some problems. 


If i use Safari all is ok. But if i use firefox the display goes off an on and I have graphics errors.


The sleep mode does not work anymore. Only the display is off and i must reboot the laptop.


Audio does not work. Both kexte are in L/E AppleHDA_ALC292.kext CodecCommander.kext


can someone help me?

For audio, let's go with another approach. Remove AppleHDA_ALC292.kext

Repair permission and rebuild cache

Mount EFI partition, add Lilu.kext + AppleALC.kext to /E/C/k/Other

Open Config.plist with Clover Configurator, under Devices/Audio Inject, change 1 to 12 and under kextToPatch, disable all the AppleHDA patches except the HDMI stuff.

Reboot and you should have audio hopefully.
