Hi everyone, After three months of using IMAC I cannot continue like this. On my Imac (21"5 2010 week 03) I had 5 to 10 crash with deferent applications per day. Only the Mail doesn't crash. When I buy this MAC everyone said MAC is stable. But I never met that with my Windows Xp ! Apple care asked to me to restart with couples of keyboard fonction to have two bip on startup. But it's still unstable... What do you think about that ? Someone had the same experience ? Thank' you.
