How To Fix Your MacBook Screen Flickering [2026]

TL;DR:

MacBook screen flickering is primarily caused by software bugs or incorrect display settings that can be fixed through system adjustments, though issues accompanied by colored lines or distortion upon moving the lid point to physical hardware failures.
    ● For MacBook Pro models equipped with dual graphics, turning off Automatic graphics switching forces the device to use the discrete GPU and bypasses integrated graphics glitches, while all users should try disabling True Tone, Dark Mode, and browser hardware acceleration.
    ● Resetting the PRAM/NVRAM by holding Command + Option + P + R for 20 seconds during startup safely clears underlying display settings, but resorting to a full macOS reinstallation via Recovery Mode will completely erase all device data.
    ● If standard software troubleshooting fails and the glitching manifests as colored lines, shaking, or worsening when adjusting the screen angle, the problem stems from a failing GPU or loose display cable requiring professional Apple-authorized repair.

MacBook Screen Flickering Doesn't Mean You Have a Serious Issue

While your MacBook Pro screen flickering can be nerve-racking, it's not always a sign of critical failure. Many MacBook owners experience this issue occasionally, the problem being most common with the 13-inch MacBook Pro from 2016.

Of course, just because it's not always a sign of bigger underlying issues doesn't mean you should ignore it when it happens. Even if it's a minor thing causing your screen to misbehave, it could spiral out of control unless you take the steps to solve it quickly.

Therefore, it's always in your best interest to look into a MacBook Pro or Air flickering screen fix as soon as you encounter the issue for the first time.

Ways You Can Fix Screen Flickering on MacBook

There could be a few different solutions depending on why your MacBook screen is flickering. In general, if you aren't sure what's causing the issue, you should start with simpler solutions, such as restarting your Mac or updating your software. If the issue persists, you could then try the more advanced fixes. Take a look.

Fix 1: Restart Your Mac

While it might seem silly, sometimes turning your Mac off and back on or simply restarting it could be just the thing you need when your MacBook Pro or MacBook Air screen is flickering or glitching.

Sometimes, display glitches are caused by your computer getting confused about all the processes it needs to perform. In a sense, it's similar to losing your way while wandering around in an unfamiliar city - returning to your starting location can help refresh your memory and allow you to find your way.

Restarting does the same thing for your Mac. It clears its Random-Access memory (RAM) and helps your computer start all processes from scratch.

Therefore, just:

1. Go to the Apple Manu;
2. Click Restart;

   

3. See if that solves your screen issues.

If your MacBook screen is still flickering, you can try one of the other solutions mentioned below.

Fix 2: Update Your macOS

Using an outdated OS presents unique risks - not just for your display. Apple's updates commonly come with essential fixes and features that improve your devices' performance, enhance security, increase privacy, and ensure compatibility with new software/hardware. They also come with important patches and bug fixes that could help you solve your MacBook Pro/Air display flickering issues.

To update your macOS, just follow these few steps:

1. Go to the Apple Menu > System Settings;

   

2. Select General;
3. Click Software Update > Update Now.

   

On older Macs, the software update will be available under System Preferences instead of System Settings.

Fix 3: Toggle Off True Tone and Automatic Graphics Switching

Display optimization features can occasionally create rendering loops between your MacBook's integrated and discrete graphics processors, leading to visual stutters.

1. Disable True Tone Adaptability (Isolate ambient light sensor loop glitches)
   Navigate to the Apple Menu > System Settings > Displays. Locate the True Tone toggle switch and turn it Off.

   

2. Deactivate Automatic Graphics Switching (Force your Mac to use a single graphic processor)
   Go to System Settings > Battery. Click on the Options button at the bottom right. Uncheck Automatic graphics switching to prevent your Mac from stuttering when swapping video hardware layers. (Note: If this option is missing, your MacBook model features only a single integrated graphics card).

Fix 4: Turn off Automatic Graphics Switching

In all likelihood, your MacBook has two graphics systems and the automatic graphics switching option enabled by default. This feature helps you improve battery life and overall computer performance, as your Mac will automatically switch between the graphics systems to better suit whatever app you're using at the moment.

Unfortunately, this feature can also cause Mac screen glitching, so you might be better off turning it off.

To turn off automatic graphics switching, follow these steps:

1. Go to the Apple Menu > System Settings/System Preferences > Battery;

   

2. Scroll down and click Options;
3. Deselect Automatic graphics switching.

   

If you don't have this option, your Mac has only one graphics system, and this solution won't be effective for your device.

Fix 5: Disable Browser Hardware Acceleration

If your display flashes only while browsing websites or streaming video content, your browser's hardware rendering layer is likely experiencing a driver conflict.

• For Google Chrome Users: Click the three-dot menu icon in the upper-right corner > Settings > System. Toggle off Use graphics acceleration when available, then relaunch the browser.

  

• For Mozilla Firefox Users: Click the three-line application menu > Settings > scroll down to the Performance header. Uncheck Use recommended performance settings and uncheck Use hardware acceleration when available.

  

Hopefully, the problems with Mac screen flashing should be solved after following these steps.

Fix 6: Boot Into Safe Mode

Safe Mode forces your machine to load only essential operating system extensions while systematically running an internal directory check on your primary boot drive. The safe mode gives you an array of repair options that can help you troubleshoot common issues like MacBook Air black screen of death and screen flickering. Here's how you can enter this mode:

• On Apple Silicon Macs: Shut down your Mac. Press and hold the Power Button until the "Loading startup options" window appears. Select your main hard drive volume, press and hold the Shift key, and click Continue in Safe Mode.
• On Intel-Based Macs: Turn on your Mac and instantly press and hold the Shift key. Release the key the second the Apple login window displays on your screen.

Fix 7: Flush Corrupted System and App Caches

Accumulated system cache directories can become corrupted over time, misdirecting display data sent to your monitor monitor.

To clear cache on your Mac, follow these steps:

1. Open the System Go-To Directory (Navigate hidden system paths safely)
   Open Finder. Press Shift + Command + G to call up the path search bar.
2. Target the Cache Folders (Locate cached storage zones)
   Type /Library/Caches into the field and press Enter.

   

3. Purge Corrupt Cache Records (Remove temporary data files safely)
   Select the non-essential application folders inside this directory, move them to the Trash, and immediately empty your Trash. Restart your device.

As a nice bonus, clearing the cache will also create more room in your storage.

Fix 8: Reset NVRAM / PRAM (Intel-Based Macbooks Only)

Non-Volatile Random-Access Memory (NVRAM) stores configuration settings like screen resolution, display color depths, and startup disk selections. Restoring this memory to factory defaults eliminates persistent display errors.

Apple Silicon Note: If your MacBook runs on an M1, M2, M3, or M4 series processor, a dedicated NVRAM reset shortcut does not exist. These chips test and reset hardware profiles automatically during every standard restart.

1. Power Down the Laptop (Initiate a completely clean shutdown state)
   Turn off your Intel MacBook completely and wait until the cooling fans stop spinning.

   

2. Execute the NVRAM Reset Key Sequence (Hold the correct four-key combination)
   Press the Power Button, and then immediately press and hold Command + Option + P + R together on your keyboard.
3. Hold Until the System Reboots (Confirm hardware verification triggers)
   Keep holding all four keys down for roughly 20 seconds. You can release them after hearing a second startup chime or after the Apple logo appears and disappears for the second time.

Fix 9: Perform a Clean Reinstallation of macOS

If deep system caches or corrupt core system files are causing the screen flickering, a clean operating system installation will fix it.

Critical Backup Warning: Wiping your drive partition to reinstall macOS will delete all your local files. If your screen flickering prevents you from accessing a standard backup routine, deploy Wondershare Recoverit within a bootable recovery drive environment to extract and safeguard your essential documents before proceeding.

Once your personal data assets are secure, trigger macOS Recovery Mode:

• Apple Silicon: Turn off the computer. Press and hold the Power Button until the options display, then click Options > Continue.

  

• Intel Processors: Turn on the computer, then immediately press and hold Command + R until the Apple logo appears.
• Select Reinstall macOS from the utility menu window and click Continue to run the clean platform installation.

Give your device some time to reinstall your OS. Afterward, check to see whether your screen is still glitching.

Fix 10: Seek Professional Help (if all of the above methods fail)

If you've tried all the abovementioned solutions and your screen is still glitching, you might need professional help. The repair cost for screen flickering on MacBook Pro or MacBook Air can vary depending on precisely what's causing the issue, but you should be prepared to spend a few hundred on it.

Contact the closest Apple-authorized service providers to learn what they can do for you. Moreover, to be safe, always back up all your essential data before sending your device in for repairs.
