Currently, I am running mac osx (version 10.5.8). My processor is a 2.26 Ghz intel core 2 duo, and I have 4gb 1067 Mhz DDR3 ram on a macbook pro. Out of the 500gb I have on my computer I have 35gb free. I tried closing everything down and restarting it, but this isn't helping. Compared to when I first bought this laptop I am running at, i would say, less than 1/5 its original speed. For instance when i scroll or click on links or programs it doesn't scroll up right away for 1-2 seconds. That is just one example. Has anyone had this problem or would you be able to recommend anything?
