10.6.8 imac I looked at the activity monitor again and noticed that Quick look uses alot of CPU. All I know is that it is something to do with previews. I only use my computer for ripping, burning, downloading movies, movie converting, itunes, audio converting, iphoto, P/S elements 10, emails, uploading photos, editing audio, printing & copying. Do I need Quick look? Would it affect my computer in some undesirable way if I removed it? Also, how do you remove it?
