had my new imac for 9 days, it has been amazing until today- I was on facebook and also trying to find a photo in my external hardrive at the same time. Then it froze, It wouldnt close facebook or the external hardrive...I tried to shut down, it wouldnt do anything, color beachball spinning forever......except all of the apps on the bottom worked fine, the mail, the dashboard, i photo, calender, etc.....but Safari was not responding. I left it like that for a few hours and when I returned it was sleeping, it did allow me to force quit the opened apps, BUt then I got a blue screen with a grey waiting wheel....I waited 10 minutes... and then I decided to hold down the power button...when I powered it back on it was fine, works great again. My question is I have 4 days to return it, I can get a brand new one- SHOULD I??? I feel like I got a lemon and am thinking I should take advantage of the 14 days return policy.... ??? What do you think?
