How to Fix the Horizontal Black Lines on Your MacBook Pro Display

Did you know that you’re not the only MacBook Pro user who’s tired of seeing those black horizontal lines that go right across the screen’s top menu bar? Although some users are petitioning Apple to recall these defective devices, no word has come out yet about the company replacing them for free.  

These black lines can be a warning sign that some of your laptop’s internal components are failing. In most cases, heat is the common factor that triggers these lines to rear their ugly heads. For instance, they’ll likely appear later in the day after using your MacBook for long periods for video editing or work. So, what can be done about it?

How You Can Mitigate the Horizontal Lines

First, you have to make sure that you give your MacBook a break from time to time. Also, it’s best to keep it adequately ventilated by running a fan behind it. If possible, shut your MacBook and use an external display.  

Troubleshooting Tips You Should Try

Take a Screenshot

Before you decide to take your laptop in for service, be sure to determine if the horizontal lines are a display issue or a graphics issue by taking a screenshot. This will make it easy for you to explain the problem.

You may be dealing with a display issue if the horizontal black lines don’t appear in the screenshot. However, if they do, then you may have a GPU issue.  

Reset the SMC (System Management Controller)

• Shut down your MacBook and unplug its peripherals and its power cord.
• Next, wait for about 15 seconds before plugging your device back into its power cable.
• Before turning it back on, wait for another five seconds.

Reset the PRAM (Parameter Random-Access Memory)

• Shut down your device and find the Command, Option, P, and R keys.  
• Next, turn on your laptop and press and hold these keys simultaneously right before the gray screen appears.
• Release the keys as soon as you hear your MacBook’s startup chime for the second time.
