I have a 2012 MacBook Pro. Very little use. Never even got warm. I downloaded google chrome browser the other day, and it gets hot, fan goes on high, wheel spins like regret. I can't blame it on google chrome. My memory, and cpu aren't using a worrisome amount of resources? I am wondering why Google chrome would cause this problem--if that's the problem? From a programmer's perspective? (I did turn off Apple automatic update, and install.)
