How to Fix MacBook Screen Flickering?

Restart Your Mac

Let’s turn to the basic part. Use the Power button to turn off your MacBook to restart it. This type of problem might look serious, but it will basically fix this issue. So, close all applications and restart macOS. If the MacBook screen flickering issue is software-related, you should try this first to check it out. 

Click on the small Apple icon in the upper left corner and select Restart.


Resetting NVRAM (non-volatile random access memory) or PRAM (parameter random access memory) means restoring all system-critical information, like date and time, display, the boot disk, current graphics configuration, and others. So, resetting these memory chips will fix the display issues if you messed up your display settings. 

Here are the following steps to reset NVRAM or PRAM:

  • For resetting either your NVRAM or PRAM chips, shut down your MacBook first
  • Once the MackBook is switched off, press the power button to start the boot-up process.
  • Now, press and hold the Option + Command + P + R keys and release these keys after approximately 20 seconds.
  • The MacBook will get restarted.

Update macOS

Apple usually comes up with new updates that carry important bug fixes and feature updates. For keeping your MacBook up-to-date, you should install all the available macOS updates with time to fix the Mac device screen. However, don’t forget to take back up using Time Machine. So, update macOS to the latest stable build to fix the screen flickering issue. Follow the steps below.

  • Open the System Preferences menu on your Mac.
  • Go to the Software Update section and check for major pending updates. 

If there are any updates available, it’s time to install all the updates and ensure your MacBook is running as per the latest version of macOS. Restart your device and see if it fixed the screen issues.

Disable Automatic Graphics Switching

MacBook Pro has two separate GPUs, a standalone graphics chip and an integrated chip. The standalone chip handles the tasks related to gaming or video, whereas the integrated chip handles web browsing or word processing. Setting automatic graphics switching makes the device more reliable and efficient in terms of battery life. However, it also causes screen flickering. So uncheck it and see if the problem persists.

  • Press the Apple icon>System Preferences from the menu to proceed.
  • Select Battery in the System Preferences menu. In the Battery menu, press the Battery option on the left
  • Disable the Automatic graphics switching
