Hi Newbie here! My friends imac G4 is super slow, it was fine until a few weeks ago but has gone really really slow especially when clicking between applications. I have no mac experience but am quite handy with PC's so said I'd have a look for her, and so I defragged, deleted trash, restarted, ran virus and spyware detection - the hard drive is about 60% free and I couldn't spot anything that would be causing this, but it really is so slow. She has operating system 10.4.11 - 1.25ghz processor and 256 mb ram, I know I could just add more ram but it was fast enough for her a few weeks ago and she's noticed a considerable drop. I have captured the activity monitor (attached) and was hoping someone could tell me if there is anything suspicious running here - my friend says she doesn't know what any of this stuff is other than firefox, safari, norton, excel and itunes. Failing that, are there any good freeware mac programmes I could run to try asnd improve things? Thanks in advance.
