Brightness slider missing - OpenCore Catalina

5 posts in this topic

Recommended Posts

I have followed this tutorial and added SSDT-PNLF to ACPI directory. Also modified WhateverGreen. Removed any brightness kext from /Library/Extensions. Also added ACPIBacklight kext to opencore kexts. However, I still can't adjust brightness. What should I do? EFI has been attached.

Display clearly appears as external screen so you'll never get any slider bar until it registers as built-in LCD. Check your SMBIOS settings make sure you're not using an iMac or MacPro profile but that of MacBookPro11,1 (Haswell iGPU model). Adjust your OC config accordingly.
