I have a 2009 iMac with 2.66 GHz Intel Core 2 Duo 2 GB 1067 Mhz DDR3. Initially came with 10.5, upgraded a couple years ago to 10.6.8 and then a couple months ago upgraded to 10.8.5. Was running slower so did some things to help clean it up like emptying trash, cleaning up desktop, repairing the permissions, etc. which seemed to help some. Still tends to run slow when we have multiple programs open, especially Powerpoint/Excel/Photoshop. I assume this is due to the relative lack of memory and/or slow processor since it is five years old. Any suggestions how to upgrade to help it run faster for reasonable cost, or is it not worth it at this point? I am only as computer savvy as I need to be to use the various programs so please speak plainly if you want to get technical. Thanks!!
