DO NOT USE this app! This app will permanently effect your system's fan control settings even after you uninstall it. I uninstalled it and my system no longer changes it's fan settings according to the load automatically. For the time being, I am using smcFanConrol to keep my system from overheating. From what I have found, the way to fix this is to restore the firmware for your machine, but I have not been able to find the proper firmware disc for my Particular MacBook Pro, (MacBookPro3,1), so I havn't been able to restore my firmware. If anyone can help me, please reply. Much help would be greatly appreciated. Mac Update should pull this app, and the developer should pull it until this potentially catastrophic issue is fixed.
