My iMac fell on the floor and is still operating expeditiously but there is a crack that is somewhat visible but not massively visible. It extends from the top left hand corner of my iMac to the center of the computer screen and back down to the right hand bottom corner. Even though the crack covers a large area, the crack did not penetrate the computer and looks like maybe a cat scratched it or a slight laceration to someone's arm.
It is not essential to get this fixed but I would like to if possible. I have tried the eraser method, the Vaseline method, and hand sanitizer. Any ideas?
