[Guide] Laptop backlight control using AppleBacklightFixup.kext

[ahmed_shiko]

Your ACPI configuration is not per guide.
You have an existing PNLF (a brightness patch) applied in DSDT.aml.
As per post #1, SSDT-PNLF.aml provides PNLF, not DSDT.
Read post #1 carefully.

ok how remove patch PNLF IN DSDT.aml

Make sure you're using correct tools.
Correct tools are linked from the guide:
https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

Otherwise you will need to provide details (specific error messages, version of iasl, etc).

I compiled and install IASL with the instructions from the guide. Screenshot

Looks like you're using the wrong version of iasl.

What is the output of:

iasl -v
which iasl

iasl -v
which iasl

iasl -v

It is the wrong version of iasl.
The current version (on bitbucket) linked by my guide is:
