Macbook Air boot menu defaults to external monitor Took a while to figure out why the screen stays black during boot, but I eventually found that the boot menu and apple logo are by default going to an external monitor. I have tried to fix this by resetting the default display in system preferences, SMC and PRAM resets, but to no avail. I'm at a loss as to what is causing this to happen, and can't seem to figure it out. Any help would be appreciated!
Dragging the status bar (in Display Settings) to the screen you want as default worked for me! :)
