[Guide] Laptop backlight control using AppleBacklightFixup.kext

[RehabMan]

Sorry, here you are!

Why are you using iMac17,1 with a laptop?
The ioreg shows GFX0, not IGPU. This guide requires GFX0->IGPU rename.

Why are you using iMac17,1 with a laptop?

Because during config.plist creation, I thought that iMac17,1 was nearest to a Skylake configuration (I was choosing MacBookPro but I'm not an expert so I chose basing on better-matching CPU in Clover Configuration).

This guide requires GFX0->IGPU rename.

I'll try to set it again! Thanks

Best to stick with a laptop SMBIOS for your laptop.

Here with DSDT patch, still no changes (I surely did something wrong)

The GFX0->IGPU patch you have in your config.plist is entered incorrectly.

Maybe this obvious, but after updating to 10.13.2 via the App Store I had to update the kext cache to get backlight control working again.
A simple

sudo touch /System/Library/Extensions

and a reboot had everything working again.

The 10.13.2 update removed my AppleBacklightInjector.kext entirely (unless it was there in /L/E and I missed it). I had to re-install it and clear kext cache.

The update will not remove AppleBacklightInjector.kext.
Certainly, the need to rebuild cache is normal/expected after any update.
