I am working on a Mac (OSX 10.4) that has had several users and upgrades. How do I create a backup of the entire system (not necessarily my working files)? I want a disk I can boot from and restore all the Adobe software I have installed. I often wondered about software if my Mac went to toast. I have the system disk, but how would I re-install all software. Would I just have to have current serial numbers and cds? Not all previous versions and serial numbers? Sorry it is a simple question, I know, but I have never had to deal with this end of the Mac before. I have always just been an operator.
