Normally I would use Command F1 to make the external monitor active but there is no F1 key on the touch bar. Also the screen is broken so i can’t get into system preferences on the primary display. Need to turn off autoboot before putting new display on. @danj
I just spoke with an Apple employee over the phone and she said that if you disconnect the battery before doing anything else you should be fine and fastboot shouldn’t be triggered. Someone is going to lose their job… LOL
