I bought a MacPro five years ago.

In the afternoon, it shows a yellow line in the screen.

I restart it several times, but is still there.

I google it. Most of people said that if your Mac is 2013 around, it will has this problem.

Did any one have the same problem? How do I deal with this problem? Do I have other options to fix this except changing the screen!

Frist off, "Mac Pro" does not come with a screen. What you have are called "MacBook Pro".

Display failure are common across any LCD, they can happen randomly. It could be manufacture defects. But most of all are cause by mis-handling, drop or bang physically. It might not occur immediately after the incident. It could takes up to months or years.

There are usually no other option than replacing the defective LCD.
