Alright guys heres my problem
I recently purchased an Alu iMac in the summer. I was experiencing problems with it ever since. the first problem was the constant freezes which were soon resolved by a software update
. But now a newer problem has surfaced. I constantly receive this error message. The "Application quit unexpectedly". So I take my iMac to the Apple store in Toronto and the genius there was very nice. He ran some tests and determined that my issue was not hardware related. He then cheerily popped in a Leopard disk and did an Archive and Install of MAc OSx Leopard. HE said that perhaps this would fix my problem. Although I am happy to be running Leopard right now I still experience this problem. applications quit around once or twice every week. How often does this happen to you guys? I plan to visit the Apple store again this weekend but I dont know how to approach this problem. Any suggestions? When apple fails me I can always count on Macrumors to deliver
