I have been researching google and the forums trying to answer my question but can't get a straight answer. I have a backup of one of my mac programs that is a collection of what I believe are .dmg files. I had them as a large rar file with the many files inside. What I am trying to do is convert the many .dmg files into one that can be recognized by the mac, preferably an .iso or something that will boot. Has anybody had this problem? What seems to be the solution.
