Hello, I am looking to install OS X El Capitan on a 1,1/2,1. I have already made many adjustments for doing so, but I am stuck. I have an install app for installing the OS, which of course doesn't work. I want to create an "installed" .dmg file, then simply restore it to my target drive. My problem is that I simply don't know how to do that. I am a little bit of a MacNewbie. I would really appreciate any help!
