I am using a MacBook pro-2103 later, fans are making a lot of niose . I went to the apple store and the genius performed the colling diagnosis and said the hardware is fine and I may have to format the system. I checked my activity monitor and there is a particular process which is taking a lot of CPU time and i tried quitting but am not able to quit the process, please help me find a way to do it. Thank you
MacBook Pro with Retina display, iOS 8.4.1
