I have a I believe a '09 version pro. Running on snow leopard. Processor Speed: 2.26 GHz Memory: 2 GB Version 10.6.8 It always ran great and never had a problem with speed. Up until about a month ago, I know this semester has been rough on it, I used to keep it at home, but now I have to lug it around everywhere. I keep it in a speck case and inside my backpack. I do update it on schedule, I back it up to an external harddrive on occasion and haven't installed anything new in months. Lately it runs VERY slowly usually freezing and programs fail to open. I downloaded a memory manager from the App store and I watch it drop to 2MB Free all the time, just simply by trying to load google. I only keep Firefox, mail and stickies open. Very rarely anything else. Sometimes pages. Do I need to upgrade my memory or what? I am not very tech savy so not sure what I can do, people who work at the tech place at my school are trying to sell me a whole new mac saying mines shot but I don't think so either way I can't afford a new one.
