Any suggestions for my slow running iMac? Any hurried-up browsing or multitasking gives the dreaded beachball for minutes on end. I tried the HDD diagnosis and permissions fix, but nothing changed or improved. Recently, if we rebooted the iMac a small earth globe appears in the center of the screen for about 2 minutes, followed by the Mac happy face for another two minutes. Very frustrating! Am I wasting my time or is there more I could be doing to salvage this iMac? We've begun to move important documents and photos in case disaster strikes!
