I'm going to be moving in a month. I brought 2 new macs within the past 3 months (one macbook and one 24 in imac). However, I'd like to be able to just leave a copy of one of my mac's restore disc at my old house and just bring the other recovery disc with me. So can I do this. Can I interchange one recover disk for another and still restore either one of my macs with it?
