Step-by-Step Guide: How to Fix a Dim MacBook Air Screen
Here is a clear and straightforward guide to help you troubleshoot your M3 MacBook Air’s dim screen:
1. Check the Brightness Settings.
- Sometimes, the brightness slider gets pulled down accidentally.
- Use the F2 key or the slider in the Control Center to manually raise the brightness.
2. Turn Off Auto-Brightness
- Your Mac adjusts brightness automatically, but sometimes too aggressively.
- Go to System Settings > Displays and disable Auto-Brightness.
3. Update macOS
- Bugs in older system versions can affect screen performance.
- Make sure you update your macOS to the latest version.
4. Reset NVRAM and SMC
- These minor resets often fix display glitches.
- You can restart your Mac by holding down Option + Command + P + R, or you can look up the SMC reset steps.
Why Does This Happen?
The M3 MacBook Air uses adaptive brightness sensors to adjust to your environment. While this usually helps, sometimes the sensors misread lighting conditions, making your screen stay dim even in bright rooms.
Additionally, certain background apps or software bugs might interfere with display settings, causing your MacBook to wake up looking darker than usual.
