Ok, so I have an iMac 24 inch with 2GB of ram so you would think it would be pretty fast right? I don't know what's wrong with it but its very slow. I have migrated info from my old macs to this one but the old ones never had this problem. Its like my mac has a virus or something. I would turn on the computer and check activity monitor and my free system memory would be around 700MB+ and by not doing anything and leaving it alone it would continue to fall and fall and by just letting it go it would hover to about 12-40MB of free system memory. Safari among other things is painfully slow as well as constantly crashing. I can't get any use out of this. Anyone have any trouble shooting idea's?
