Hey, gang... long time no post. I've noticed (for a couple of months now) that my iMac simply isn't as fast as it once was. I have the Intell 2GHz Intel Core Duo iMac with 1.5 GB of RAM. Anyway this machine over time has gotten progressively slower-- specifically with some applications-- the two I've noticed most (that are causing extended "beachballing") are Mail and iChat. Mostly the Mail program-- sometimes when I hit reply/reply to all it takes a LONG time for the reply email to actually open up. For the most part it's just a general feeling of the machine running slower as I'm still able to run all the programs that I ever had. I'm wondering if it's perception and I simply need a bit more RAM or if over time something in this OS clogs up the way a Windows registry might (I know there's no registry-- just trying to create an analogy here). Is there something else I might try doing? Is there some pref file that I can delete restore or something. I've done a bunch of searching here and haven't found much. Any advice will be tried and is appreciated. Thanks!
