I have the older macbook pro and I've taken good care of it over the past couple years, but it seems like that hasn't mattered. I've always had a pc so I'm not exactly sure what I could do to fix it. Things just don't load as fast as they used to and firefox and safari freeze more than they should. My battery lasts all of 5 minutes, but I'm guessing for that I just need to buy a new battery. Any suggestions? Maybe i need to run some sort of virus scan?
