I did a search about my slow and getting slower iMac C2D, and found a thread that mentioned Onyx - Got Onyx - cleaned cache. also noticed replies mentioning Cocktail and TinkerTools also - got those too. goofed around a bit, and now, i have no screensavers... when i try to find any screensavers, there's a black screen and it says its that it's looking for the folders. it never finds anything, and when my imac goes into screen saver, i get black screen forever...
any ideas what i did or how i can fix it???
