[Guide] Laptop backlight control using AppleBacklightFixup.kext

RehabMan said:
Your ioreg shows AppleBacklight not patched.

Not 100% sure what this shows but it looks like it is patching it.

EDIT: On a side note, after I posted above and said I was going to edit my signature, I made the signature edit and saved it then my account was deleted? reached my username and found old posts that all say I'm a guest. I recreated the account with the same exact username but I lost my signature. Not sure how that happened.

Then add the other Txxx profiles (with M/L/D/LD/DL suffix) to AppleBacklightInjector Info.plist
F14TxxxxM
F14TxxxxL
F14TxxxxD
F14TxxxxLD
F14TxxxxDL

Do I just add new children to the ApplePanels with these Keys? What about the Values?

Made these changes. Debug message now says patched 6 times, however, still no brightness control (slider or keys).

EDIT: Also still no backlight when wake from sleep. Typing this with a flashlight :lol:

Your ioreg shows that the modified AppleBacklightInjector.kext is not installed.

Also, note kextcache output (super obvious problem...):
Code: 
AppleBacklightInjector.kext has incorrect permissions; omitting.

You might want to find out where AppleBacklightInjector (the old one) is loading from, because obviously, it is still installed somewhere... (as per data in ioreg).

Still none of the profiles in ApplePanels matches what the system is expecting.
You will need to experiment with other profiles... note:
