Recently, my computer has been acting strange. I have only had my MacBook for 1 year. My applications have trouble working when I have a couple of them open. I am constantly getting the color spinning wheel, and when I am using iTunes my music stops and starts randomly. I have tried deleting my preferences folder, using Onyx and cocktail to fix and clean up my computer. Someone please help I do not want to have to get a new computer after 1 year. Do I need more RAM or something? I am only using 20% of mac's memory. It is really slowing me down from doing my work. Ask me for more information if I have forgotten anything.
