props dude, really enjoyed watching the videos on your YouTube channel, and glad to see you implemented a solution to fix the issue with the display brightness. After a friendly fellow pointed me to your
MacBook Pro dGPU Disabler.app I was able to bring an old 2011 15" MBP back to life ♂️ which I am pretty stoked on to say the least. That said, other than the brightness not being able to be modified, ie. only having one level of brightness after running the above mentioned app something else that I have noticed is that if the hard drive goes to sleep then the computer never fully "wakes up", and what I mean by that is if I set the screen to go to sleep after 1 minute. The screen will go black, then I can press a
shift key on the keyboard and the desktop screen will illuminate. That said, if I set the hard drive to sleep after 1 minute of inactivity along with the display, ie. both display and hard drive have been set to sleep after 1 minute of inactivity, the computer appears to wake from sleep because I can toggle the
caps lock and notice how the green LED will light on and off, however the screen remains black. Is this something you have experienced? In closing, thanks again for your efforts, and even more thanks for sharing your findings. I put a little album together of my progress
here
Final question, did you performing the disable of the dGPU on Sierra allow you to control the brightness without the hardware mode? I ask because when reading this thread I remember reading someone mentioning that hw brightness worked if the box was running Sierra.
cheers
