Hi All, I ran into an issue out of the blue yesterday. All of sudden, my iMac started hanging up on me. It started getting really slow and whatever i click, seemed like it would take forever to load. The spinning wheel would happen for about 30 seconds, then the app would open up. Larger apps (photoshop, etc.) would take a little longer. I tried running disk repair (which took all night to run) next morning, when I restarted, same thing, it hung. I tried running in safe mode, but nothing, just the apple loading screen. I read somewhere to try cmd + option + p + r to reset the pram, but still nothing. I thought maybe it could be the ram, so i replaced it with my back up ram but same thing. I'm out of ideas, anything?
