I'm doing a full rewipe of my HD and I have some programs installed on here that I don't have install discs for, GarageBand in particular. They came on the computer when I bought and I'm assuming aren't carried on the 10.5 upgrade I installed. I'm not too familiar with mac, but since everything is drag and drop friendly, can I just drag them from the applications folder to an external HD and drag them back when i'm done?
