I have a late 2008 macbook aluminum (which has been an outstanding computer for the last three years) and I am noticing some issues with the trackpad. I suppose it behaves mostly normal, but I am noticing that several times a day the curser will freeze and not move even though I am moving my finger on the trackpad. Also, I have the sensitivity turned to the highest, but it feels like the trackpad is becoming duller and less responsive. Often I have to redo my finger movement because the curser is not responding like it used to. This leads me to believe that the trackpad is starting to wear out. My computer is covered by apple care (for 1 more year) so do you think I should contact Apple? Is there something I could do on my own to fix the trackpad or would apple fix it? Thanks for your feedback.
