@Feartech can you help me get keyboard to control brightness on my dell 7573? I have everything working just cannot find option to change brightness with keyboard. I've tried accessibility and keyboard preferences. thanks bro
best to check the laptop guide sections and see how other's have patched their keyboard brightness keys

Hi! Slightly different issue, but still related. Over at Macrumors forums, we are trying to make 2011 iMacs work with upgraded GPUs, especially kepler based nVidia cards: k2000m, 750m, 780m etc... Replacing the card is fine, works out of the box, however we are loosing brightness control in MacOS. The brightness control works under linux, probably bacause it already includes system-specific hacks to make it work(https://wiki.archlinux.org/index.php/Backlight)

Wondering if anyone has experience using these modified brightness kext with an iMac? Would it be possible to make it work?

Thanks!

all your kexts belong in there

config.plist InjectKexts should be set to Detect

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:
