how to cool down my mac?
I have had my computer for about 3-4 years and the battery has overheated once already. My mac was getting really hot and I got the battery replaced. That was about a year ago but recently, I feel like my mac is getting really hot again. The fan turns on but it is still hot. I don't want it to overheat again because paying for a new battery is expensive. Is there any program or things I can do so it won't be so hot? I have reduced necessary usage but anything else?
