Ok, so I bought a new MacBook Air on June 22nd, today, It froze so I force shut it down, I turn it back on and it won't boot properly, at first, it wouldn't even go to the apple logo, so I tried going into recovery, it couldn't repair the drive (index key), it also won't mount or reformat. The next thing I try is going into safe mode, when I go into safe mode, it is still grey with black boxes around the text, then it shuts down and reboots to the Apple logo, the bar when it updates the firmware, then the spin wheel, then it shuts down. I also ran the diagnostic utility and it said everything was fine, what do I do now?
