I have MacBook pro retina 13" 2013 and few days ago installed Fan Control and removed it on the same day without changing any fan settings. Yesterday I saw some suspicious warnings in Console and read that some more steps are needed to fully uninstall Fan Control. So I removed /Library/StartupItems/FanControlDaemon and there was no /Library/PreferencePanes/Fan Control.prefPane Now I am wondering whether I should do SMC reset to completely delete Fan Control.. I see that it might be harmful, so my question would be how to know if Fan Control has made any changes on my machine? Maybe facts that there was no /Library/PreferencePanes/Fan Control.prefPane or that I did not change anything mean that SMC reset is unnecessary? That is, I am not sure how Fan Control works, i.e. if it changes anything else than fan settings (which, I guess, are fine).
