Why is my CPU over 300%
Little over a day ago, I dropped my Mac Book Air, not a very high drop, and in the morning I noticed that computer was running extremely slow and the fan instantly started when the device turned on. I checked my CPU % and it was running fluctuating from 300% sometimes to 2000%... I didn't know what to do I'm not very tech savvy. I also noticed that my sound isnt working.. and there is no option in sound preferences for MacBook Air Microphone. Can anyone help?
