I run a computer lab for a high school. We have about 150 computers in need of a new clone. I recently upgraded to El Capitan and I have found endless literature on how to clone using previous platforms. But none for this new system. I have been working on this for over a month, I have downloaded super duper, and carbon copy cloner. I have tried to make a disk image and set it up on another computer. When I did disk image it was finally in a .dmg file. But it still would not transfer properly to the other computer when I did command+r to get to disk utility. I know how to put a clone on a new computer, I just do not know how to make the clone itself. Nothing I seem to do works. I do not know if I am missing a step, but it is just not working.
