If you can now see an ‘OK’ message, the next step is to input the ‘Reboot’ command followed by pressing ‘Return’.

Reinstall MacOS or OS X
Ok, so if you have come this far then there is not much in the way of going back. When you reinstall MacOS or OS X you’ll lose data on your device, unfortunately. I know this is not the desired outcome, but if you have reached the point where it is more important to be up and running again from a nuts and bolts perspective, then I’m going to guess that you’ll decide to take the jump with this.
So you may be ready to do a full reinstall to overcome white screen on your MacBook Pro, but before you do anything this drastic, double check your device and work through steps 1 to 3 again, just in case. I’ll be here hoping this fixes the white screen of death for you. If not, and you want to push on, then you will need to complete a full reinstall.
