🖥️ What Is MacBook Screen Flickering?
If you’re wondering how to fix MacBook screen flickering, it’s important to first understand the issue. Screen flickering on your MacBook can range from subtle flashes to intense blinking that makes the device nearly unusable.
While it might initially seem like a minor glitch, persistent flickering typically indicates deeper software or hardware problems that require attention.
Common Symptoms Include:
- Quick, random flashes or blackouts
- Screen flickers when adjusting brightness or opening apps
- Horizontal or vertical lines briefly appear
- Flickering only at certain angles or while charging
- Affected during movement or lid adjustment
Hardware or Software: Which One Is It?
- If flickering starts after a macOS update → likely software
- If flickering occurs with lid movement or at angles → likely hardware
- If flickering is constant, regardless of tasks → could be GPU or display IC related
🔍 Common Causes of MacBook Screen Flickering
Understanding the root cause is key to fixing flickering for good.
1. Software Bugs or macOS Glitches
Sometimes updates introduce display driver bugs. Beta versions and recent major macOS releases are often culprits.
2. GPU or Driver Conflicts
MacBooks with discrete GPUs (Intel + AMD/NVIDIA) may suffer from flickering due to automatic graphics switching or bad GPU drivers.
3. Flexgate and Hinge-Related Issues
On 2016–2018 MacBook Pro models, backlight cable tension caused by hinge movement leads to flickering—known as Flexgate.

4. Display Cable Damage or Loose Connection
Cables that route through the hinge area can get pinched or loosened, causing flickering at certain lid angles.

❓ FAQs – How to Fix MacBook Screen Flickering
Will flickering go away on its own?
Unlikely. If it’s hardware-related, it worsens over time. Software-based flickering might be fixed with updates.
Can AppleCare cover flickering screens?
Only if it’s due to a manufacturer defect. Flexgate was briefly covered by Apple’s extended program.
How do I test if it’s software or hardware?
If the flicker occurs only at angles, or when moving the lid—it’s hardware. If it appears during specific apps, try Safe Mode.
Can screen flickering damage the MacBook long-term?
Yes. It can stress internal circuits and eventually kill the backlight or entire display.
Is it cheaper to fix the cable or replace the screen?
Cable or hinge-related fixes are always cheaper than replacing the full Retina display.
