If possible, you should exercise good maintenance skills to keep it from ever getting that bad.Ĭleaning dust out of a Mac isn't as easy as cleaning dust out of a PC, but it's not impossible. You've seen the kind of crud that can build up on your keyboard and mouse, right? Imagine that happening inside your computer. Not only that, but if you leave the dust lingering too long, it can turn into gunk-and gunk is harder to clean and can cause more problems. Dust buildup can be a serious problem for all kinds of electronic equipment.
