Weird screen for one user account but not the others. Why would that happen?
One day, the MacBook got a weird screen that prevented me from seeing anything on it. When I made a second user account, the screen was normal. From then on, I did everything from the second user account. After a while, I deleted the original user account. All the user accounts I made since then have had a normal screen.
Why would the screen get messed up for one user account but not the others? Thank you in advance.
