Software Fixes for Screen Flickering
If your MacBook Pro‘s screen is flickering, the first step is to try these software troubleshooting tips, in order:
1. Update macOS and Apps
One of the most common causes of screen flickering is outdated or buggy software. Make sure your MacBook Pro is running the latest version of macOS and all apps are up-to-date.
To check for macOS updates:
- Click the Apple logo in the top-left corner of the screen.
- Select "About This Mac" and click "Software Update."
- If updates are available, click "Update Now" or "Upgrade Now."
Best practice is to enable automatic updates in System Settings > General > Software Update. This ensures you get important stability and security fixes as soon as Apple releases them.
To update apps:
- Open the App Store and click "Updates" in the left sidebar.
- Click "Update" next to any apps that have updates available.
For apps not downloaded from the App Store, check the developer‘s website or the app‘s built-in update tool.
2. Restart Your MacBook Pro
If updating software doesn‘t resolve the flickering, the next step is to restart your MacBook Pro. This clears out temporary system files and gives your Mac a clean slate to work with.
To restart normally:
- Click the Apple logo in the top-left corner of the screen.
- Select "Restart…"
- Click "Restart" to confirm.
If your screen is flickering so badly that you can‘t click the buttons, you can force a restart by holding the Touch ID / power button until your Mac shuts down.
3. Reset PRAM/NVRAM
PRAM (Parameter RAM) and NVRAM (non-volatile RAM) store settings related to your MacBook Pro‘s hardware, including display settings. Resetting this memory can resolve screen flickering issues caused by corrupted settings. Here‘s how:
- Shut down your MacBook Pro completely.
- Press the power button and immediately hold down the
Command+Option+P+Rkeys. - Keep holding the keys down until your Mac restarts and you hear the startup chime for a second time.
- Release the keys and let your Mac start up normally.
Note that this process is different for MacBook Pros with Apple silicon (M1/M2 chips). On those models, the memory resets automatically on shutdown, so you don‘t need to hold any keys.
4. Check Display Preferences
There are a few settings in System Settings > Displays that can sometimes lead to screen flickering if not configured properly:
-
True Tone: This feature automatically adjusts the color temperature of your display based on ambient light. If the sensor is dirty or malfunctioning, it can cause flickering. Try turning True Tone off to see if it makes a difference.
-
Night Shift: This setting gives your screen a warmer hue after sunset to reduce eye strain. In some cases, it can interact poorly with other display settings and cause flickering. Turn off Night Shift in System Settings > Displays to test.
-
Scaled Resolution: If you‘ve changed your display resolution from the default, it could cause issues. Go to System Settings > Displays > Display Settings and click "Default for display" to revert to the recommended resolution.
-
Refresh Rate: Some MacBook Pros allow you to change the refresh rate of the built-in display or external monitors. If you‘ve customized this setting, try changing it back to the default 60Hz to see if it resolves flickering.
5. Test Safe Mode
Safe Mode is a special diagnostic environment that starts your Mac with only the essential drivers and software needed to function. It‘s a great way to isolate issues caused by third-party apps or extensions.
To start up in Safe Mode:
- Shut down your MacBook Pro completely.
- Press the power button and immediately hold down the
Shiftkey. - Keep holding
Shiftuntil you see the login window. - Log in as usual. You should see "Safe Boot" in the top-right corner of the screen.
If your MacBook Pro‘s screen doesn‘t flicker in Safe Mode, it‘s likely that a third-party app, extension, or login item is causing the issue. You can try uninstalling recently added apps or extensions and see if the problem persists.
Hardware Troubleshooting for Screen Flickering
If you‘ve tried all the software fixes above and your MacBook Pro‘s screen is still flickering, it‘s time to consider hardware issues. Before you schedule an Apple Store appointment, there are a few diagnostic steps you can try:
1. Run Apple Diagnostics
Apple Diagnostics is a built-in tool that can detect problems with your MacBook Pro‘s hardware, including the display. Here‘s how to use it:
- Disconnect all external devices except the power cord.
- Shut down your MacBook Pro completely.
- Press the power button and immediately hold down the
Dkey. - Keep holding
Duntil you see a screen asking you to select your language. - Choose your language and wait for Apple Diagnostics to finish running.
If any issues are found, make a note of the error codes and reference codes provided. These will help Apple support or repair technicians diagnose the problem.
2. Check for Physical Damage
Carefully inspect your MacBook Pro for any signs of physical damage, especially around the display housing. Dents, cracks, or gaps in the casing could indicate damage that is causing the screen to flicker.
Pay special attention to the hinge area where the display connects to the base. If the hinge is loose or wobbly, it could be putting strain on the display cable and causing intermittent flickering.
3. Test an External Display
If possible, connect your MacBook Pro to an external display using an HDMI or Thunderbolt cable. If the flickering only occurs on the built-in display but not the external one, it‘s a sign of a hardware issue with the internal screen.
If flickering occurs on both displays, the problem is likely with the graphics card or other system components rather than the display itself.
Advanced Fixes for Stubborn Flickering
If none of the above steps have resolved your MacBook Pro‘s screen flickering, you may need to try some more advanced troubleshooting techniques.
Warning: These steps involve deleting system files and reinstalling macOS, which can cause data loss if done improperly. Make sure you have a complete backup of your important files before proceeding.
1. Reset the SMC
The System Management Controller (SMC) is responsible for managing many of your MacBook Pro‘s hardware functions, including the display. Resetting the SMC can resolve issues related to power management and graphics performance.
On MacBook Pros with a T2 security chip (2018 and newer), you can reset the SMC by following these steps:
- Shut down your MacBook Pro.
- Press and hold the power button for at least 10 seconds, then release it.
- Wait a few seconds, then press the power button to turn on your Mac.
On older MacBook Pros without the T2 chip, follow these steps instead:
- Shut down your MacBook Pro.
