Dell 5548 Hd5500 Audio etc. problem on Mojave

Recommended Posts



İ have Dell 5548

i5 5200u Broadwell


8gb ram


Im made clean install Mojave and I try my old High Sierra working kext and clover file but audio hd5500 and brightness doesn't work now. And I think external graphic card not disabled because cpu fan work too fast and drain my battery. Thank for helps.


Edit:I must remove Appleintelbdwframebuffer.kext because not boot with that kext.


Send me MacBook-Air.zip

How do you expect to have graphics with QE/CI if you delete the kext responsible for it (Appleintelbdwframebuffer.kext)?

You'll need to restore it.

The discrete is disabled, it's not showing up in the IOReg. You're probably just don't have power management enabled.

Here, replace attached files into /EFI/Clover. If still not brightness, then move AppleBacklightInjector.kext into /L/E

Repair permissions and rebuild cache
