So i'm in no way new to my Mac, But I'm not a pro either. But we've been coming into a few problems lately. One is that it keeps over heating and shutting down. I've researched it online with out any success. Another is that when I go to empty the trash, there's always a few hundred things to been deleted. And I'm positive that I didn't put that much in there. I try to delete it every few days. But i'm starting to get worried that its deleting important files, because my mac is starting to slow down. Any help?
