I'm trying to troubleshoot video issues on macbook laptop with no display or a dead? display but can't see what I'm doing. I need a Terminal command to run 'blind' after I boot into Single User mode & enable an external monitor. Hence- How do I enable an external display in Single User Mode via Terminal on a headless macbook?
