Hi everyone Has anyone had the issue when starting there iMac up where they get a flashing folder with a question mark? I had it recently and was causing me nothing but grief. In the end i decided to leave it turned off for about 1 hour and went back with no hope of it coming back to life, after reading all over the net it sounded like it could be a faulty installation (well got corrupt) or fault HDD. But when i powered it back up it worked first time and i could log in successfully, I ran a system update and installed all the updates that were waiting for me. Ran a disk and permissions check which returned no errors. I havent had any more problems with it up to date so maybe the system update fixed the issue. How many other users have had this issue?
