It's weird. I have the correct version on usr/bin folder but terminal loads a wrong one.

Is it possible to have a path to a second version somewhere else? How do I check that? Thank you.

In Terminal:
Code: 
which iasl
 
thank you Mr.Rehabman. I read it 5x and understand.now its working fine now. cheers. :)

Terminal says "/usr/local/bin/iasl" :rolleyes:
How to set the correct version for use in terminal?

Remove the iasl at /usr/local/bin/iasl if you expect to be using the one at /usr/bin/iasl.
 
Hi. Mine isn't working. My display stays at full brightness and no brightness slider in Sys Prefs. Do I have the correct ACPI files and patches on config.plist?

EDIT: Fixed it by removing dynamic SSDT's. It's working, I have better backlight levels but when I use the keyboard to change brightness, the transactions are not smooth like it was with IntelBacklight.kext. Is this normal?
