Hi, I've had my iMac for just over a week now. I have AppleCare until February 2016. 1. I thought I had a dead pixel but upon closer inspection it seems to be just a bit of dust. It's very distracting having a black spot on the screen. Will Apple do anything for me? 2. Is the glass on the Magic Mouse supposed to slide to one side? Mines does and it the aluminium underneath sticks out enough to catch my thumb. Also very distracting. Is this normal? If not, will Apple give me a replacement mouse? Thank you very much.
