As the title suggests, my iMac just keeps getting slower and slower. I don't know what to do. I get the beach ball almost every time I try to open something. I have Leopard and the computer ran fine for about a year or so after I up graded but recently (the past few months) it has just gotten very sluggish. I have 1 gig of RAM which I'm thinking might be part of the problem (i might need more) but that doesn't explain why it ran fine for so long and is now running slow. If anyone has any suggestions for getting my iMac back up to speed, please let me know. Thanks in advance!
