I have a MacBook aluminum from late 2008. It has the 2 ghz intel core 2 duo processor, 4gb of memory and 160gb hard drive. Right before mountain lion came out I erased everything on the computer and then put the iOS on and restored from a backup on my time capsule. Recently I have been having issues with pages,keynote and safari crashing. I have also noticed that when loading stuff i get the spinning wheel. Now today my trackpad will not move my cursor sometimes. I have restarted it and its still acting up. The only thing I have done recently is downloaded 3 mix tapes from datpif and downloaded stuff from professors. What can I do to get my computer working good again? Thanks in advance!
