Hi everyone, totally new here so sorry if this has been asked before. I recently upgraded to osx lion via the app store and since then when i start my mac i get the white screen with apple logo and a bar that loads up slowly, once loaded the desktop opens with a bit of a stagger in the graphics. if i then open itunes and play a song nothing happens and i also have no wifi connection. if i do a restart it's absolutely fine. I took it in to the apple store the guy plugged in an external drive and checked something and said it was all ok he then done a hardware check and said this was also fine no problems take it home. it was fine for the first to start ups (one a day for 2 days) then reverted to the same old problem which has now really freaked me out. Could it be a power supply issue or the lion upgrade or did it just need a breath of fresh air, any help greatly appreciated.
