10.12.4 IntelBackLight.kext doesnt work anymore

[Ninjuan]

The patch_backlight.sh script assumes _UID=10, and assumes a pattern of F<uid>T<display-id>, which corresponds to format "F%uT%04x".

If you look at the code in AppleBacklight (or even 'strings' output), you will see several other possibilities...

F%uP%04x
F%uT%04xM
F%uT%04xL
F%uT%04xD
F%uT%04xLD
F%uT%04xDL
F%uT%04x
F%uS%04x

I'm pretty sure I wrote about all this stuff in my guides/posts from years ago...

ah seems like i understand now. the patcher itself creates the correct value, i dont need to look through the original info.plist and search for the correct one.
