Now a days, MacBook users observing screen flickering issue after using it for a while is becoming common. In this issue, screen suddenly turns black for a second or so (in some case up to 30-40 secs) before coming back to normal and it keeps on happening after certain interval of time. You might think there is some hardware problem started occurring in your screen and you might immediately want to contact Apple care for support. You will be amazed to know that majority of the times(if not every time) users can fix this issue by themselves without taking the burden to contact Apple service center.

This issue may happen in old as well as in new MacBook Pro or in any other MacBook with apple silicon. The cause of this issue could be multiple. It may arise due to compatibility issue between OS and GPU. Sometimes it may also happen due to glitches in software or missing updates in system. Some other factors like loose wired connection in case of external display, power adapter fluctuations, duplicate color profiles can't be ruled out. In the worst case, flickering might happen due to hardware damage as well.

  • Go to Apple Menu
  • Click on System Preferences
  • Click on Battery
  • Go to Battery section showing on the left side
  • Then uncheck Automatic graphics switching
  • Restart your system

For those of you who don't know, automatic graphics switching is a feature in some MacBook models in which system will switch between different graphics processing unit (GPUs) based on demand. This feature is used for enhancing battery life without compromising the performance. By default, this feature will be checked and enabled which means GPUs are managed by the system. Unchecking this option will make use of discrete GPU only which may increase the performance but at the cost of battery life. So make note of this.

 

Solution 4: Check for loose connections

If you are using any external display then flickering might happen due to loose wired connections to the port. You can verify this by gently shaking the wire yourself and see if it is indeed the culprit. You can also unplug and re-plug the connections and make sure it is plugged properly to the port. This is such a small cause of the problem but often it goes unnoticed.

 

Solution 5: Reset NVRAM or PRAM

If you are using intel based MacBook system then resetting nvram or pram might also help in solving screen flickering problem. To perform reset, follow below steps:-

  • Shutdown your Mac system completely.
  • Power on the system and immediately press Option+Command+P+R simultaneously for 20 seconds.
  • System should restart with nvram or pram reset.

Sometimes changing screen resolution will also help solving the problem of flickering issue. If you already tried previous steps and did not helped much then I would recommended you to do the following:-

  • Go to Apple Menu on top left corner of your screen.
  • Select system preferences from list of options
  • Go to Displays
  • Change Resolution to Scaled and try different resolutions.

 

Solution 7: Disable True Tone

If changing screen resolution also did not helped much then I would next suggest you to try disabling True Tone and see if this helps. For that you have to perform below steps:-

  • Go to Apple Menu on top left corner of your screen.
  • Select system preferences from list of options
  • Uncheck True Tone

For those of you who don't know about True Tone, it is basically a features in Mac devices to automatically adjust colors and intensity of your displays based on different ambient lighting conditions.

Many times it has also been observed that duplicate colour profiles tends to cause screen flickering issue. So if the previous solutions did not worked then I would recommend to try deleting the duplicate color profiles using below steps:-

  • If you see same colour profile then delete one of them.
  • To delete select the duplicate colour profile and click on (-) button
  • Click on Done

  • Go to Apple Menu on top left corner of your screen.
  • Select system preferences from list of options

  • Hold down the Shift+Control+Option Keys along with the Power Button at the same time.
  • Hold all the keys for about 10 secs.

  • Finally press the Power button to turn MacBook on.
