I tried so many kexts and patches to get the brightness slider in system preference but did not succeed.

I am using OpenCore Bootloader.

Can someone please check the files that I have uploaded in detail and guide me what should I do.

Please do not give me links to the old posts as I am a real noob in hackintoshing the laptop, So live guidance would be great.

Everything on the laptop works except the brightness.

And Also I would like to know whether Opencore sets the brightness of the laptop to the max on boot even if I don't have brightness slider in my system

My Laptop Specifications:

Processor :- Intel Core i7 6700 HQ (Skylake)


Ram :- 16gb DDR4


Motherboard :- HP (820D)


Graphics :- 1) Intel(R) HD Graphics 530(BIOS Device Name = \_SB.PCI0.GFX0)


2) Nvidia GTX 960m

MacOS : Catalina 10.15.3

MacBookPro13,1 would be a better choice of SMBIOS

AppleBacklightFixup.kext should not be needed with latest versions of whatevergreen.kext

Should I just put SSDT-ALS0.aml in my opencore's OC/ACPI folder and remove the AppleBacklightFixup, and also change my smbios?

yes
 
My laptop does not have ambient light sensor so I don't think SSDT-ALS0.aml will work

I changed SMBIOS to MacBookPro13,1
Removed the AppleBacklightFixUp.kext

Still the brightness slider is not available.

zip and upload your OC folder
 
missing ALS0.aml

your kexts needs updating

00001B19 would be a better ig-platform-id

add a:
device-id -> Data -> 1B190000

also add model -> string -> Intel HD Graphics 530

example of config.plist from my guide attached

Can you please tell me which kexts need to be updated.

I have updated the platform id like you suggested.

Should I first reboot and see if everything works or wait until. you suggest the kext updates

use hackintool, that can scan and download the kexts for you
