why is my screen flashing

I have a MacBook Air 2019 edition. When I turn it on the screen begins to flash from to sign in point and does not stop until I turn the MacBook off/restart it.


This has happened a few times now. Does anyone know why this may be?

  2. Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
  3. Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
  4. Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.
