MacBook Air 15" M4 A3241 (2025) Screen Repair
Compatible models: A3241, EMC 8850
The MacBook Air 15-inch M4 uses a 15.3-inch Liquid Retina display with True Tone, P3 wide colour and a brightness of 500 nits. It is one of Apple's most capable thin-and-light displays, calibrated at the factory for consistent colour and brightness across the entire panel. When the screen is cracked or failing, that calibration is gone. We replace the display panel itself, restoring full Liquid Retina performance with True Tone and P3 colour intact.
- Turnaround: 1 to 3 working days, subject to parts
- 12-month warranty on the fitted display
- Walk-in near Liverpool Street Station or use our UK mail-in service
Why the panel replacement matters on this model
On the MacBook Air 15-inch M4, the display panel carries the True Tone and P3 colour data that makes the screen look the way it does out of the box. Fitting the correct genuine panel ensures all of that is preserved. Here is what that means in practice:
- True Tone preserved: the display continues to adjust colour temperature to match your environment automatically
- P3 wide colour maintained: photos, video and design work display with the full factory colour range
- 500-nit factory brightness restored: no reduction in maximum brightness from aftermarket parts
- Touch ID unaffected: Touch ID is built into the power button on the keyboard, not the display. It functions normally after a screen repair
- No non-genuine display notice: a genuine panel fitted correctly will not trigger any service or non-genuine part alert in System Information
- Camera, microphone and Wi-Fi verified: all three are routed through the lid and are tested after every screen repair
