Hi people.... I love my mac, and I know people swear by them... but lately, things have just been falling apart on my mac... For starters, note the weird graphics on the dock in the attachment. Secondly, my mac doesn't always shut down, it sometimes stalls on the blue screen with the spiral thingy and other times it just stalls on a blank desktop. Then I get other strange, irregular problems from time to time, I am wondering if I am doing something wrong or if I should just start again. I have a RevA MBA, running Snow Leopard. Thanks! Joe.
