@Ocytoxin,
Rebuild your kernel cache.
@the-darkvoid
First, thank you for your answer!
I tried, but it doesnt change anything.
Here is the output i get :
mbp-de-loic:~ lobo$ sudo kextcache -i /
Password:
Kext with invalid signatured (-67062) allowed: <OSKext 0x7f858a81a6f0 [0x7fffa60fd8f0]> { URL = "AppleBacklightFixup.kext/ -- file:///Library/Extensions/", ID = "com.hieplpvip.AppleBacklightFixup" }
AppleBacklightFixup.kext - dependency 'as.vit9696.Lilu' not found.
AppleBacklightFixup.kext is missing dependencies (including anyway; dependencies may be available from elsewhere)
KernelCache ID: 54FA3CC2817C148F8C96BCE870D18012
Kext with invalid signatured (-67062) allowed: <OSKext 0x7f90dedfb950 [0x7fffa60fd8f0]> { URL = "AppleBacklightFixup.kext/ -- file:///Library/Extensions/", ID = "com.hieplpvip.AppleBacklightFixup" }
I have no idea how to fix kenel dependencies, should I look into it? Or is it likely to be related to something else?
