(This is all occuring on an intel iMac 1.73 core duo, 1gb ram, OS 10.4.11) Where to start, about 3 days ago my mac took ages to boot, it just sat on a plain white screen before eventually loading the white page with the apple. Sometimes I have to restart at that point because it doesn't get anywhere. It still happens at least once a day. I have my dock hidden and it's not responding when I go to the bottom of the screen, it appears if I click but then when I go to hover over a different application the magnification doesnt follow it. My volume keys on my keyboard and remote havent been working. Expose hasnt been working either. And finally when I hover over an icon the pointer doesnt change and it doesnt highlight the icon I'm over. This is also occuring with the toolbar at the top of the screen. I havent installed anything since last monday and that was only BFD2. On some restarts it's ok, it's doing ok this time but I have unplugged most of my USB's and firewire. These items include 2 external harddrives, my phone charger, my ipod cable and my logic key. Any ideas would be truely helpful cos I'm at a loss for ideas. Thanks.
