Solutions to Fix MacBook Screen Flickering
Restart Your MacBook
A simple restart can often resolve minor glitches, including screen flickering. Save your work, close all open applications, and restart your MacBook to see if the issue persists.
Update macOS
Outdated software can sometimes cause screen flickering. To update your macOS, go to System Preferences > Software Update and follow the on-screen instructions.
Adjust Energy Saver Settings
Energy Saver settings can cause screen flickering when working improperly. To adjust these settings, go to System Preferences > Energy Saver and experiment with different settings to see if the issue is resolved.

Automatic graphics switching can cause screen flickering if it isn’t working correctly. To disable it, go to System Preferences > Energy Saver and uncheck the box next to “Automatic graphics switching.”
Check External Monitor/TV Connection
Connect your MacBook to an external monitor or TV to determine if the issue is related to the display or cables. If the problem persists on the external display, it could be related to the GPU or macOS.

For MacBooks with a T2 security chip, shut down your MacBook, press and hold the Control + Option + Shift keys, and then press the power button while holding these keys for 10 seconds. For older MacBooks, shut down your MacBook, press and hold the Shift + Control + Option + Power buttons simultaneously, and then release them.
