Black Mac Screen Upon Boot:
Disconnect External Display:
If you have an external display connected, then you may be using your Mac as an extended display. So, unplug it.
Reinstall the macOS:
Nothing would be lost. It's just that misplaced items would be placed back to where they should be and corrupt system files would be replaced by clean files. Go Here: Reinstall macOS - Apple Support. Use the third bulleted method: [command + r]. To prevent data loss, be sure to back up your Mac with Time Machine, prior to the reinstall.
