When I start my Mac it starts running this program that makes my laptop's fans stars going as fast as they can and my laptop starts over heating. I looked into my activity monitor and it showed my activity and my laptops activity I was using 5.00% of my laptops duo core and my Mac was using 54.00% on a program called netsession_Mac_8d9378b. It's been doing this for maybe a month now and it's starting to scare me. My laptop has less battery because of the amount of power going into this program i need help. I like my Mac and I don't want to see it die a slow and painful death what's happening?
