First off, Hello. I have an aluminum 2.66 iMac with 2Gigs of ram. Recently I've have to restore it quite a bit due to it slowing down to a snail's pace. I purchased it sometime in Feb of last year, so its a April 2008 release (checked PN too). I know it maxes out at 4 gigs, so I ordered them this morning, and wil replace them when I get it. The hard drive was just reformated and the original 10.5 was installed and fully updated before anything was installed. I'm trying to grasp on why it might be slowing down. I've read that if heat was an issue, that it would shut itself down, so I don't think that is the case even though I live in Florida. I used Onyx before I reformated to check the status of the HDD and it said everything looked fine. I don't really use it for gaming or anything like that, so I don't see how it can be slowing down like it is. I am starting to become a little depressed with it, and so I come here to get some ideas of what I can check and/or do? Thank you for your time.
