How to Fix the Screen Flickering Problem on MacBook Pro
As Apple's flagship notebook, the MacBook Pro has long been praised for its reliability and smooth user experience. However, even premium devices can encounter technical issues—one of the most common among users is screen flickering. Whether you're using a newly purchased MacBook Pro or an older model, flickering displays can occur unexpectedly and disrupt your workflow.
This article explains the common causes behind the MacBook Pro screen flickering issue and provides the most up-to-date solutions in 2025 to help you restore normal display functionality quickly.
What Is Screen Flickering on MacBook Pro?
In simple terms, MacBook screen flickering refers to rapid shifts in screen brightness, colors, or sudden flashes. Sometimes, parts of the screen may stutter, change color unexpectedly, or appear unstable. This problem can be caused by minor system bugs, display settings, or even underlying hardware issues.
Common Causes of MacBook Pro Screen Flickering
Understanding the root cause is crucial to fixing MacBook display problems. Here are the most common triggers:
1. Software or System Issues
Outdated macOS versions, incompatible drivers, or software conflicts can cause abnormal screen refresh behavior. Bugs introduced in certain macOS updates may also lead to flickering.
2. Display Settings and External Devices
Incorrect screen refresh rate, the auto-brightness feature, or incompatible connections with external monitors or dongles can all result in flickering or unstable screen output.
3. Hardware-Related Failures
-
Loose display cable: The internal cable connecting the screen to the motherboard can loosen over time due to wear or accidental drops.
-
Graphics card issues: GPU failure or driver-level incompatibility can cause refresh glitches or screen tearing.
-
Damaged LCD panel: Physical damage or aging components in the display panel itself may require screen replacement.
How to Fix a Flickering MacBook Pro Screen
1. Restart Your MacBook Pro
A simple restart can often fix temporary system glitches that lead to screen flickering. Before diving into more advanced solutions, restart your MacBook and check if the issue resolves.

2. Update Your macOS
Outdated software is a frequent cause of MacBook Pro screen flickering. Apple regularly releases updates that patch bugs and improve compatibility.
Steps:
-
Go to System Settings > General > Software Update
-
Download and install the latest macOS version
Updating to the newest release can often fix macOS screen flicker issues, especially those caused by system bugs or compatibility problems.
3. Reset NVRAM/PRAM
NVRAM (non-volatile random-access memory) stores system settings like display resolution and brightness.
Steps:
-
Shut down your Mac
-
Turn it on and immediately hold Option + Command + P + R for 20 seconds
-
Release the keys after hearing the startup sound twice or when the Apple logo appears and disappears twice
This process can resolve flickering related to display settings.
4. Reset the SMC (System Management Controller)
The SMC controls hardware-level operations like power management and display behavior.
Steps:
-
Shut down your MacBook
-
Hold Shift + Control + Option + Power button simultaneously for 10 seconds
-
Release all keys and power on normally
Resetting the SMC can resolve MacBook display flickering issues related to hardware control.
5. Disable Automatic Brightness Adjustment
The auto-brightness feature sometimes misreads ambient lighting and rapidly changes screen brightness, creating a flickering effect.
How to turn it off:
-
Go to System Settings > Display
-
Toggle off Automatic Brightness Adjustment
This step is particularly useful if your screen flickers under changing lighting conditions.
6. Boot into Safe Mode
Booting into Safe Mode helps isolate whether third-party software or extensions are causing the screen flicker.
Steps:
-
Shut down your Mac
-
Turn it on and immediately press and hold the Shift key
-
Release the key when you see the login screen
If the screen doesn’t flicker in Safe Mode, it's likely caused by a third-party application or startup item.
SEO Tip: Many how to fix MacBook flickering screen searches relate to conflicts with third-party software—Safe Mode helps identify them.
7. Disconnect External Devices
External displays, USB-C adapters, and docks can cause screen issues if there's a poor connection or compatibility problem.
What to do:
-
Unplug all external monitors and accessories
-
Restart your Mac and observe the screen performance
This will help you determine if external hardware is causing the flicker.
What If the Problem Is Hardware-Related?
If none of the above solutions resolve the flickering, you may be facing a hardware issue.
Common Hardware Causes:
-
Loose screen cable: Often occurs after physical impact or long-term use
-
Graphics card failure: Can affect how the screen processes and displays visual data
-
Defective LCD screen: May require full display replacement
Recommendation: Contact an Apple Authorized Service Provider for a diagnostic test. If your MacBook is still under warranty, repairs may be free. If not, request a repair quote before proceeding.
