I need some more help here....
My iMac is from 2007 and it is starting to slow down quite a bit. There is still more than half the memory left on it. I was not sure if there is anything I could do to "clean" it up a bit? I know with PC's you can de-fragment them. Was not sure if there was such a thing on a iMac.
Any help would be appreciated. Also please put it in simple terms. I am not the best with software .
