Vertical lines on MacBook screen
My cat slept on my MacBook Pro keyboard when I left it open. The display is a series of vertical grey, black and white lines. How do I reset the display?

- Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
- Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
- 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-
- Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.
Thats all I have for now. Beyond the above recommendations, You can have your MacBook Pro examined at the Apple Store or an Authorized Service Center when they open or contact ➔ Apple Support
