"Macbook fan running fas and performance low: I have macbook air mid 2013 11”. It was working super fine yesterday I put it into sleep mode and after few hours I opened it, the mac was running very slow and fan was super fast. I restarted the mac, reset it and still the condition is same. Also the performance is same in safe mode."
