How to Fix MacBook Screen Flickering?
The issue with the MacBook screen flickering has several potential fixes. Each Mac may respond differently to this hardware and software interactivity test, so it is worth attempting each one in order before determining whether the screen flickering problem is still present or if one of the fixes has resolved it.

Many MacBooks have two graphics cards installed. Additionally, they have the automatic graphics switching feature enabled so that your computer may use the optimum graphics card for the task at hand while also preserving battery life. The two graphics systems, however, occasionally contribute to screening flickering. To disable a setting:
- Select System Preferences > Battery from the Apple menu.
- On the window’s left side, select the Battery option.
- You’ll see a menu of possibilities. Uncheck the item for automatic graphics switching. This setting is in the Energy Saver settings in macOS Catalina versions 10.15 and earlier.
- Your machine has one graphics system if automatic graphics switching isn’t indicated.
Solution 3: Disable Dark Mode or True Tone

Screen flickering can potentially result from both features.
To turn off Dark Mode:
- Click General under System Preferences from the Apple menu.
- Look at the Appearance category, which is the first one in the new window.
- Choose Light as your initial option.
- The mode of your screen will switch from dark to light.
To turn off True Tone:
Click Displays under System Preferences from the Apple menu. Select your display by clicking Display Settings after connecting more than one display.
To disable True Tone, uncheck the corresponding checkbox.
Solution 4: Check for hardware issues
Hardware acceleration is used by third-party browsers like Chrome and Firefox to enhance rendering effectiveness and performance. However, certain hardware setups may experience problems as a result.
Consider disabling hardware acceleration for your browser if the flickering screen issue only happens while you’re using the browser to perform tasks like streaming video. Go to Settings > System in Chrome by clicking the three dots symbol. Disable when hardware acceleration is possible, use it.
Solution 5: Enter a Safe mode

Remember that in Safe Mode, your computer may perform slowly, and your screen resolution may be reduced. Check out our instructions on how to start your computer in Safe Mode when you’re ready.
