My mum has a 2007 iMac, running some OS that has the App Store. It is incredibly slow. I'm talking 30 second waits to open System Preferences. She doesn't care, as she rarely uses it. But soon she has to work from home for a week, so she'll need to use it. Is there anything that can be done to speed it up? Would a reinstall of the OS do anything? It seems to constantly be using 1.99/2.0gb ram, though I fail to see what's actually using that much, it lists about 500mb in use at any one time.
 
A reinstall would be the easiest option I guess. Make a Time Machine backup, reinstall OS X from scratch (erasing your existing partitions), and restore only the documents, images etc from the backup.
But you should be able to see in the activity monitor what process is eating all the memory.

That's what I thought. I did an estimate on the memory usage, and it sits probably around 400-600mb. Though it says apps alone are taking up 1.2gb, it makes no sense.
