Hello, Someone who is definitely interested in my iMac is coming to visit it on Wednesday, and i need to try and get it greatly optimised in order to make a great impression on it. I was thinking of first formatting the hard drive, then restoring it using Time Machine, but i don't want many of the applications installed. Ideally i'd only like iTunes + content, Pictures and a few Applications and settings to be kept. Could there be a way of doing this? So when thats done, is there any other ways of able to speed the system up? My iMac usually takes 80 seconds to boot up to the Desktop, and i'm trying to get it to only 50.. Any help would be appreciated, thanks!
