Hello guys, so i have a Macbook Air Mid 2013 with Yosemite and i never had problems with my fan. Only when gaming the fan get a bit louder and the macbook hot. But after i've updated Safari to 9.0 (El Capitan Update or something) the fan is always on! Even if only Safari is open. What can i do? Activity Monitor says that Safari is using 132,5% CPU... Is that normal? Everything else is using >8 CPU :O Or has it something to do that my Macbook is now like 1-2 years old and i should clean the fan? Is this even normal?
