Can the retina Macbooks be run with the internal display unplugged from the logic board? This was always no problem in the past. I'm asking the question before just trying it because magic smoke is usually expensive to waste. I don't seem to specifically see any examples posted to the internets. Google searches want to tell me how to use closed lid mode. Unplugging the retina display from the logic board and removing the assembly. Then connecting an external monitor and booting. Can you do this?
