I need to move some of my data to another mac mini but I only have one display (which is ATD) and a very small office space. What would be the best way to access the files on the "old" mini running headless? I have an extra TB cable, but I am not sure if linking it to the TB port on the display would work. Both minis are 2012 model, so they only have one TB port each. I would like to avoid dual display/keyboard setup or copying all the files from the old mini to the external drive.
