Forcing external display as main on MacBook Pro with broken screen
The screen on my Mac book pro is broken. How do I force the system to make external display the main display?

Use Command-F1, that toggles between extended and mirroring for the external display. Alternatively, connect an external keyboard, mouse/trackpad and AC power and close the lid.
