Can anyone give me some suggestions on keeping my mini "clean"? I have a 5 year old powerbook G4 that is very slow and I am assuming it is full of various things from the past 5 years of use. I am not computer savy and would like to purchase a program that is easy to use and will keep my mini running smoothly and not get bogged down with files etc from every day use. Is clean my mac a good option? Better ones to use? I will be using the mini for school work, photoshop (minimal use), Netflix, hulu, surfing the web etc ... Thanks in advance.
