Do you experience constant MacBook Air screen flickering? Don’t know why you’re experiencing this problem? Not every MacBook user is reporting this issue. But, some people encounter it and want its quick fix.
Before getting the solution to any problem, it’s good to find out the main reason. So, here you will discover why MacBook Air’s screen flickers and how to stop it. Before visiting any local repair store, try to resolve it yourself with the below solutions.
Why Is the MacBook Air Screen Flicker?
Screen flickering lines show on retina and non-retina screens. Users notice it when graphics are enabled or disabled or while using the Terminal. It can happen due to incompatibility between GPU and the operating system. Malware can also be a cause.
Sometimes seeing the screen becomes impossible. It can be an indication of faulty hardware with the display. Physical damage, such as dropping the device from a height, can also be a culprit. The screen can also flicker by putting a sharp and heavy object on it.
Fix MacBook Screen Flickering
The modern MacBook Air models are strong enough to easily handle the screen flickering issue. There are many possible solutions to this problem based on the cause. The primary solution is to restart your Mac. If it doesn’t work, then try the methods listed below.
It is worth trying every way to find out if it stops the MacBook Air screen flickering issue. MacBook screens may also flicker in full-screen mode. To resolve this problem, you must learn how to get out of fullscreen on Mac when linked to a VDI session.
Outdated macOS Version
Running an outdated operating system on a MacBook can cause a screen to flicker. So, ensure you’re running the latest macOS. To check the macOS version, navigate to System Preferences.
Then, click on Software Update. If you find the latest version available to download, tap on the Update option. Back up all data on an external hard drive or third-party cloud storage before updating.
Automatic Graphics Switching
Another solution for the MacBook screen flickering problem is to disable automatic graphics switching. However, this feature helps switch between low-power and energy-heavy graphics chips, and it can cause random screen flickering.
Navigate to System Preferences to turn off automatic switching. Now, click on the Battery option or Energy Saver. This option may vary based on the MacBook version. Unmark the box next to Automatic graphics switching/Disable Automatic Graphics switching.
Excessive Hardware Acceleration
For enhanced rendering efficiency and better performance, third-party web browsers such as Firefox and Chrome use hardware acceleration. But, it might become a culprit for problems with certain hardware configurations.
This solution is useful when you notice that screen flickers during browser-based activities such as streaming games or videos. To disable the acceleration, tap three dots in Chrome. In Settings, tap System and disable Use hardware acceleration when available.
Inappropriate PRAM and NVRAM Settings
PRAM (Parameter RAM) and NVRAM (non-volatile random-access memory) store all the information associated with the system. Any bug with PRAM and NVRAM can lead to poor functioning of a graphics card. Hence, resetting both of them is recommended.
Not sure how to reset NVRAM or PRAM? Turn off your MacBook and press and hold Options, ⌘, P, and R for 20 seconds. Release them when the Apple logo is not visible the second time. Note that resetting can reconfigure the Mac volume and set the time zone to factory default.
Redundant Hardware Component
Running the Apple hardware test helps in determining whether flickering happens due to a defective graphics processor or a display. Press the D key while starting an Intel-based Mac. Apple Silicon MacBook users have to shut down their MacBook.
Now, turn it on while pressing Power. Release the button when the Startup Options screen appears. Press Command and D. ADP000 code will signify no issues with the hardware, while VFD001 and VFD007 denote a faulty GPU or display.
If the above tips do not stop the MacBook screen flickering issue, try restarting your MacBook in Safe Mode. It will enable just the important MacBook features and perform automatic disk checks.
To restart in Safe Mode:
- Turn off your MacBook.
- Restart it while pressing the Shift key.
- Release the key when you’re required to log in. If it solves the issue, restart your system and check other regular processes.
Here is everything you can do to stop your MacBook Air screen from flickering. If you ever have a flickering computer screen, first determine the cause and then use the potential solution.
The above simple fixes will help you to resolve the problem before it ruins your entertainment zone or working day. These methods have been proven highly effective by several MacBook Air users in getting back to what is crucial.
