How to Fix a Flickering Screen on Your MacBook Pro

A flickering screen on your MacBook Pro can really ruin your work and fun. Many people are talking about screen issues because it’s so common. Knowing why your screen flickers—either due to software bugs or hardware problems—is key to fixing it properly.

This piece aims to be your go-to for solving the flickering screen issue. It matters not if your MacBook Pro has a retina or non-retina display. By recognizing what causes the flicker and following our advice, you’re set to solve it.

Understanding the Causes of Screen Flickering

Various factors can cause screen flickering on the MacBook Pro. These factors include both software and hardware issues. Knowing these causes can help find the right solutions.

Possible Software Glitches

Software problems often lead to flickering screens. When the macOS doesn’t match well with the graphics unit, flickering may happen. Malware also plays a role, draining system resources and causing glitches. Keeping everything up-to-date and maintained can solve these issues.

Hardware-related Issues

Physical problems can make screens flicker too. Damaged connections or exposure to water, for example, can affect how well the display works. It’s important to keep all parts in good shape and securely connected. A hardware check might show problems that need a professional’s help.

Impact of External Devices and Power Supply

Using wrong cables or power sources can make flickering worse. External devices and power inconsistencies stress the graphics card. This stress can make the screen unstable. It’s key to watch over the power supply and what devices are connected to keep the screen working well.

Initial Troubleshooting Steps

Before diving into complex fixes, try some basic troubleshooting for your MacBook Pro’s flickering screen. Simple steps might solve the problem. Checking for minor issues first is a wise move.

Restart Your MacBook Pro

Restarting your MacBook can fix small glitches. It refreshes everything and might stop the flicker. It’s a fast way to check if the issue remains.

Check for Software Updates

Keeping your macOS updated is crucial. Updates often fix bugs that could be causing screen problems. Go to the Apple Menu, click on System Preferences, and select Software Update. This action can tackle various issues, including flickering screens.

Inspect External Connections

Don’t forget to check all connections if you’re using external displays. Make sure cables are tight and not damaged. Flickering can be due to loose cables. Reconnecting devices might pinpoint the problem’s source.

How to Fix Flickering Screen on MacBook Pro

If your MacBook Pro screen flickers, there are many ways to fix it. Trying out different methods might solve the problem. If the easy fixes don’t work, here are some steps to try.

Resetting the PRAM/NVRAM

One effective method is resetting the PRAM/NVRAM. This is helpful for Macs with Intel. Turn off your device, then turn it back on while pressing Option, Command, P, and R. Do this for about 20 seconds. This reset can fix display issues by refreshing key settings.

Running Apple Diagnostics

If the flicker doesn’t stop, use Apple Diagnostics. First, turn off your Mac. Then, restart it while pressing ‘D’. This checks for hardware problems. The results might explain why your screen flickers.

Resetting the SMC

Resetting the SMC is another key step. It fixes power management problems that could cause flickering. The resetting steps vary for Apple silicon and Intel Macs. See the official support page for how to do it.

Adjusting Energy Saver Settings

Changing Energy Saver settings might help too. Go to System Preferences, then Battery (or Energy Saver). Turn off “Automatic graphics switching.” This stops the conflict between graphic systems, which might stop the flicker.

Advanced Solutions for Persistent Flickering

For those who face ongoing screen flickering, advanced solutions can provide relief. These steps go beyond basic troubleshooting. They target the specific causes of flickering.

Disabling Automatic Graphics Switching

Turning off the disable graphics switching option can stabilize display performance. It is useful because automatic graphics switching causes flickering in demanding applications. Disabling it means the MacBook Pro always uses the more powerful graphics, which can stop the flickering.

Removing Duplicate Colour Profiles

If you see colour inconsistencies, it’s important to remove duplicate profiles in your system settings. These duplicates can create compatibility issues and visual glitches. Go to System Preferences > Displays, then to the Colour section, to remove any profiles you don’t need.

Checking for Malware Issues

Malware can greatly affect your Mac’s performance and cause display problems. A deep malware check with a reliable tool like CleanMyMac might find hidden threats. Regular checks help keep your Mac stable and running smoothly.

Solution	Description	Potential Benefit
Disable Graphics Switching	Switch to high-performance GPU permanently	Reduces screen flickering for graphics-intensive tasks
Remove Duplicate Profiles	Eliminate conflicting colour profiles in settings	Improves colour consistency and display stability
Malware Check	Use software to scan and remove malware	Enhances overall performance and reduces glitches

Conclusion

Fixing a flickering MacBook Pro screen starts with easy steps. Then, it moves to harder fixes if needed. Many people have found different things that can cause the flicker. These include computer bugs, problems with parts, and outside forces. By checking these areas well, you can usually find what’s wrong.

Starting with simple solutions is a good idea. Try rebooting your MacBook, updating macOS, or tweaking settings like True Tone.
