I recently bought a new macbook air and have been really satisfied in it and its my very first Mac computer. Its been about a month and all of a sudden it gets hotter and you can hear the fan constantly running as if I'm doing something that would put a lot of strain on the computer... which I'm not! I can be simply typing on my computer in class and it will start to heat up and use a considerable amount of battery in the process as if i was trying to play a game. I looked in the Activity Monitor and the only process that is running hard is the parentalcontrolsd... it is using about 90% of my CPU and I never use parental controls? I try and quitting and force quitting it and it always just bounces right back up. This is all that I can think of that could possibly be heating up my computer like this and eating up my battery. I'm used to about 6-7 hours of battery and now I'm down to about 2 1/2... please help.
