Hello I have a Black Macbook. 2.2ghz, 1GB Ram, running Snow Leopard. Recently I've been finding my laptop rather sluggish and slow when performing tasks and opening applications. Firefox will often be quite slow at performing mundane tasks as well as flicking between applications that are open which is also slow. I use a couple of apps to help clear out unnecessary files etc to help with performance and stuff but clearly this doesn't appear to be working. Any help?
