When I receive my new Mac this week I want to keep it as clean as possible. My old Mac is a 2007 model. All I really want from this old Mac is Aperture, Microsoft Office and iWork. I know MA will move all my Apps. Is there another way to safely move just these? Can I move them to an external hard drive and then move them to the new Mac? This way I would not have to use MA at all. I know others have been asking similar questions.
