first of all, excuse my poor english, I'm spanish.
After the last upgrading, Macs Fan Control don't start, even selecting it in the Apps menu or folder. It shows a window saying "Macs Fan Control application can't open" (translated from my spanish system). My OS is Sierra 10.12.2.
*** Excuse me all. It's fixed. I don't know why it was downloading a corrupted file and it won't start. Admin can delete this post. ***
