Hi, Maybe you guys can help me. I ordered online a new MacBook Air 13" with the 2ghz cpu, 8gb ram and 256 sdd. It arrived last Friday. Everything was fine until yesterday when the trackpad stopped responding. It didn't recognize 2 fingers movements, only one. The scroll up or down movement are not working. I did many tests and the problem persist. I have my wife's macbook air to compare and mine is really not working properly. You guys think it is better to return it and get a new one? or Apple Store will be able to fix this? Maybe it is a software issue? I don't know if this is related but when I first opened my new Mac I saw that the trackpad was a little bit dirty and there was a small scratch on it. I wasn't happy with this, but I could live with it. Any suggestion?
