If your MacBook display is flickering, the problem could be software, display cable wear, backlight issues, or the panel itself.
Quick checks
- Adjust brightness and test on an external monitor
- Restart and test in Safe Mode
- Check if flicker changes when you move the lid
Common hardware causes
- Display flex cable wear (Flexgate on some models)
- Panel damage
- Backlight circuit faults
For accurate diagnosis, share your MacBook model/year and a short video of the flicker.
