iMac start up clicking noise and folder, won't work at all.
For a long time now it turns on with chime, starts the clicking and than shows folder
Every time for about 7 months. I don't know what to do, I don't have any discs for it ive had the iMac for 7-8 years
Is there anything to do. And if I take it to Genius Bar do I get charged for the appointment?
iMac, iOS 6.0.1
