I would recommend you to reset the MVRAM. Here are basic steps of uninstalling it.

  • Make sure your MacBook is connected to a power supply.
  • Shut down your MacBook.
  • Restart Mac and immediately press and hold ‘Command’, ‘Option/Alt’, ‘P’ and ‘R’ keys together.
  • Hold the four keys for 20 seconds and release them after the second time startup sound comes on your Mac. If your MacBook has a security chip installed, then release the buttons once see the logo of Apple second time.

If you still face any problem then simply follow this link. You will get different methods for resolving your issue.

Thank you for your recommendation. Let me check it weather it helps or not.
