I bought a new MacBook Air 11" i5 128SSD 4GB yesterday for my son. I had a hard time with the machine from the very start. First of all when I pressed the power on button repeatedly nothing happened. After5 minutes of playing with it it finally powered on. During the first screens it said it was missing some files from OSX Lion and would attempt to re-download them 45 minutes later it finally booted up. Now I am seeing freezes after sleep. The cursor will not move for about 5-10 seconds. After doing a search here I tried resetting Pram and selecting the startup disk but nothing has helped. I also did a reinstall of Lion. Anyone have any suggestions of something to try? Thanks
