🟡 DEPENDS ON CAUSE

Apple covers display defects under the 1-year warranty. One dead pixel may qualify as a manufacturing defect, but Apple evaluates case-by-case. AppleCare+ increases your chances of replacement.

How to test MacBook for dead pixels

Use the dedicated dead pixel test tool above — it works in any macOS browser and cycles through all test colours. Press Command + Control + F to enter full-screen mode for the most accurate test.

Alternatively, use a native approach: open a solid-colour image in QuickLook (select a plain PNG and press Space) or use the Photos app with a solid-colour album. This keeps the test entirely offline and fills the display edge-to-edge.

Test conditions: dark room, brightness at 100%, Night Shift and True Tone disabled (System Settings → Displays). Disable Night Shift in System Settings → Displays → Night Shift. Work through white, black, red, green, and blue — each reveals different pixel failure types.

What a dead pixel looks like on MacBook

MacBook dead pixel appearance varies by display generation:

  • MacBook Air M4 (Liquid Retina IPS, 2560×1664, 500 nits) — Dead pixels are very small (≈0.07mm) but sharp and visible against uniform backgrounds. The high-DPI panel makes individual pixels precise — a dead pixel appears as a crisp, fixed dark dot.
  • MacBook Pro 14" / 16" (Liquid Retina XDR, mini-LED) — Dead pixels are less common due to the premium panel quality, but can occur. Note: mini-LED panels can also show “blooming” around local dimming zones — this is a separate issue from dead pixels and is a known characteristic of the technology, not a defect.
  • Intel MacBooks (IPS panels)— Dead pixels appear as persistent black dots. Stuck pixels appear as fixed red, green, or blue dots that don't change with screen content.

A dead pixel line (an entire row or column of failed pixels) indicates a display connector or driver IC failure — not a single pixel defect. This is clearly manufacturing-related and has a stronger warranty case than a single pixel. Report it to Apple with a screenshot.

Appledead pixel warranty — what's covered

Apple's 1-year limited warranty covers display manufacturing defects. AppleCare+ extends this to 3 years and adds two incidents of accidental damage coverage.

  • Apple does not publish a specific dead pixel threshold for Macs — evaluated case-by-case by Genius Bar staff.
  • A single dead pixel in a prominent area (centre-screen, near the menu bar) is often covered. Edge pixels receive less consistent treatment.
  • Go in-person to a Genius Bar — they can see the defect on your actual screen. Do not attempt a mail-in claim for a single dead pixel; in-person appointments yield significantly better outcomes.
  • Screen replacement without warranty coverage: $400–$700 depending on model and whether the display assembly or the full top case needs replacement.

Apple's policy for MacBooks aligns closely with their iPhone approach — see our dead pixel warranty policies by brand for the full comparison. For the Genius Bar process in detail, our Apple dead pixel coverage guide explains what to say and how to escalate a declined claim.

How to fix a dead pixel on MacBook

First, try the stuck pixel fix tool — rapid colour cycling can resolve stuck LCD pixels in 10–15 minutes. This works on IPS panels (MacBook Air, older Intel models) but has no effect on confirmed dead pixels or mini-LED panels.

If the pixel remains after cycling, it is a dead pixel and requires hardware repair. Book a Genius Bar appointment at your nearest Apple Store. If your Mac is out of warranty, consider whether the repair cost ($400–$700) makes sense against the current resale value — a refurbished replacement may be more cost-effective.

FAQ

How many dead pixels does Apple allow on a MacBook?+
Apple doesn't publish the exact threshold for Macs — it follows ISO 13406-2 Class II internally, which allows up to 2 dead pixels per million. In practice, a single dead pixel in a prominent area (centre screen, near the Dock) is often covered. Edge pixels may receive different treatment.
Does AppleCare+ help with dead pixels on MacBook?+
Yes. AppleCare+ extends coverage to 3 years and increases the likelihood that a borderline single-pixel defect is approved for repair. For manufacturing defects within the standard 1-year warranty, AppleCare+ also removes any ambiguity about coverage.
Dead pixel on MacBook Air M4 — is it covered?+
The MacBook Air M4 uses a Liquid Retina IPS display. A manufacturing-defect dead pixel within the 1-year warranty is covered by Apple. Book a Genius Bar appointment in-person — bring your proof of purchase and describe the defect location specifically.
What's the difference between a dead pixel and a dead pixel line on a MacBook?+
A single dead pixel is an isolated pixel failure. A dead pixel line — an entire row or column of failed pixels — indicates a display cable, connector, or driver IC failure. The line is more clearly a manufacturing defect and has a stronger warranty claim. Take a screenshot with Shift + Command + 3 to document it.
Can I fix a dead pixel on my MacBook myself?+
Not reliably. The stuck pixel fix tool (rapid colour cycling) can sometimes resolve a stuck LCD pixel on MacBook Air models. But confirmed dead pixels are a hardware failure — self-repair on a MacBook display is not practical without Apple's proprietary parts and tooling.
