I got the package while I was at work so when I got home the first thing I did was open the package. I was so excited to have a better computer that worked well and was 3 times smaller than the one I still have. I turned the MacBook Air on and the apple loading screen turned on. The first thing that I noticed was a 1 1/2 inch think line going down the screen. it was transparent but it was messing with the words and pictures that were within that area. I turned it off and tried again in the morning. The line was gone so I proceeded to set it up. the line came back so I restarted it. the same thing happened 5 times. the last time I tried the line never showed up, but when I put my Apple ID in the screen froze so now when I press the forward/backward buttons they don't do anything.
