Problem 1. I run Onyx, and when the program begins to run, it tells me that my disk needs to be repaired. When I reboot with the install disc, and repair the volume, it says no repairs were necessary. But when I restart again and run Onyx, it once again tells me that it needs to be repaired. Problem 2. Ive gone into Disk Utilities three times now to verify the disk, and all three times my iMac would freeze and I would have to reset the computer by holding down the power button. Now I have repaired the disk in the past and never had an issue, but I dont know whats going on now. I havent really seen any real issues with my iMac until the past couple of weeks. Anyone have any ideas or thoughts?
