Ok I have an iMac and a MacBook. My brother is getting a MacBook Pro for University and wants to be able to use the programs (Photoshop, Microsoft Office, etc.) on our iMac from time to time. The problem is the school gave him no install discs, they just copied a disc image to his drive. My question is, can you just copy applications from one computer to another? I know in Windows this was impossible, but on a Mac the applications seem to be more self-contained. I did copy one app successfully (Comic Life) but will doing the same work for all apps?
