"Horizontal Line on Macbook Pro with two duplicate screens.: I have a problem with my Macbook. I have a horizontal line that separates two screens. I don't have it on dual screens as far as I know. The screens move at the same time."

Thank you for the screenshot.

Troubleshooting an Overlapping App:



It appears you are using Google Chrome. So, it may be corrupt...

1. Uninstall: Google Chrome (move it to the Trash bin from the Applications menu)
2. Restart: the Mac after the uninstall
3. Reinstall: Google Chrome, getting it from the App Store
4. Restart: the Mac after the reinstall.
5. Log back in: as the same user
6. Try Chrome once more.
