I got in an a liquid damaged MBP. The internal display is not working. An external display does work but all it’s showing is the users desktop image. I need to make it the active screen so I can get into Terminal to turn off the auto-boot. I’ve forgotten how to do it. Also any hints on what to look for on the liquid damage would help. Thanks. @danj
@mayer - Did you close the lid? Using an external keyboard and mouse you should gain access to the primary display window after you close the lid.
