What to do when your mac tells you your smc has a problem
So this started when I was clearing dust out of the back of my mac apparently it didn't appreciate that and the fans started to get loud, I ran diagnosis mode and it told me my smc was failing I reset it and didn't seem to help with the fans it just made my mac a lot more laggy it does have a few bangs and a "minor" crack in the screen which a toddler did. If anyone please knows anything about how to fix the fans and smc please let me know.
