I'm currently the process of fixing a friends Mac, they have smcFanControl installed, how do I go about resetting the mac back to it's default settings and get rid of what ever control smcFanControl had over the machine?
smcFanControl just offers the ability to set the minimum fan speed. If you drag the sliders in smcFanControl all the way to the left (minimum values) these are the defaults for the computer. You can then quit smcFanControl. The SMC will automatically turn up the fans as need be - smcFanControl just allows users to specify a higher minimum speed if they find heat to be an issue.
