[Guide] Laptop backlight control using AppleBacklightFixup.kext

[RehabMan]

Used a PLIST like recommend but now I lost my ability to boot because no HD will show.....how do I fix this?

You probably forgot HFSPlus.efi.
Read the guide carefully:

I tried the injector method but without luck. I'm pretty sure that I followed all the steps but AppleBacklightInjector.kext and AppleBacklight.kext simply would not load.

When I was about to give up, I found that only a PNLF patch ( using DSDT or Clover) will do the job. I removed IntelBacklight.kext and only use a DSDT patch. Then AppleBacklight.kext & AppleBacklightExpert.kext are loaded properly, and the brightness control are working. I can confirm the method works on at least three Hackintosh laptops with two 10.12.6 and one 10.13.2.

You will have incomplete and inconsistent brightness controls with a simple PNLF patch.
You need to follow post #1.

Hi RehabMan, Sorry I'm pretty new at hackintosh i have read a lot in the forum but I do not really understand what you mean with EDID product ID spoof.

Can you please be more specific which part from post #1. have to try ?
I have already tray the patched EDID in Clover To fix it. but without luck.

If Clover can automatically detect your EDID, the easy fix is to change your config.plist such that Clover automatically injects a custom EDID with patched product-id. The product-id known to work is 0x9c7c. Just set config.plist/Graphics/EDID/Inject=true, and config.plist/Graphics/EDID/ProductID=0x9c7c

from post #1 I don't know how to use or save this one ( ruby edidparser.rb )

I have use this to solve the sleep wake problem
Clover custom EDID injection!
Using "DarwinDumper", extract the Display EDID info from laptop into a folder
Use "FixEDID.app" to create the custom EDID from the EDID.bin file.
