I think the title pretty much sums it up. I know nothing about mac's. I am a life time PC user and for some reason last year decided to buy a mac book. It has been acting kind of weird the last couple of months, but the last week or two has been doing some pretty weird things (randomly started playing "Happy Birthday" the other day, and makes dinging noises like I'm doing something when I am not), and I am not sure how to fix it. I thought Macs didn't get virus's. Does anyone have any helpful tips or suggestions? Tags: computers, help, virus Share Twitter Facebook ? Reply to This
