Hi

 

I have iMac 21 with 16 gb of RAM.

 

The problem im encountering is screen brightness controls do not work eather from keyboard nor from system prefrences.

 

Bootcamp 4.0

 

After i Install Bootcamp, screen brightness works only untull a next reboot, then i have to reinstall it again and it will not work any more.

 

Any ideas how i can fix that?

Problem solved but not by what you have offered.

 

All i had to do is to delete rEFI from my system. It solved the problem at no time.
