all your kexts belong in there

you seem to be using a smbios for a desktop machine for some strange reason?

use a decent config.plist from the laptop guide: use the one that matches your intel graphics HD Graphics 530
Link to laptop guide:

please read the faq for proper hardware profile setup:
 
Changing smbios to MacBook Pro 13,3 makes no difference...

before your next post:

please use a config.plist from the laptop guide

the one you have is awful, best not to let clover configurator create one for you

also acpi/patched is not a dumping ground, remove those bak files

what patches did you do in your DSDT.aml ?
 
Hi RehabMan! Huge thanks for your work!

I cannot get backlight control with the guide. I get the brightness slider in settings, but it changes nothing. I can change the brightness with buttons, but it happens slowly and without any indication of brightness change in the OS.

I also tried using ACPIBacklight.kext and Genericbrightness.kext - no luck. Now cleared them all from /L/E and done minimal SSDT patching - only for native PM and USB injection. Can you check what's wrong please?

Rehabman, hello!
Thank you for your continued efforts.
I read your guide, but the backlight still doesn't work. I don't know where the reason is, So ask for help and hope to get your help.. The backlight control can still be used in macos13.6, but at 10.14.5 brightness control. Can't work anymore.
Try to bring the latest
- SSDT-PNLF.aml in ACPI / patched
- Installed to /L/E AppleBacklightFixup.kext
But brightness control still doesn't work
