Known Failure Points

The most common failure types, sorted by when they typically appear.

Keyboard Key Failure

The MacBook Air 15" M2 uses the same Magic Keyboard scissor-switch mechanism as the 13" model. Individual keys can fail from debris ingress, liquid spills, or mechanical wear. Apple service replaces the entire top case assembly for keyboard issues, making even a single failed key an expensive repair.

Warning signs:
  • Individual key feeling mushy or intermittently failing to register
  • Key double-typing or missing presses
  • Backlight LED failed for a specific key
  • Key cap rocking on one side

Fanless Thermal Throttling

Like its 13" counterpart, the MacBook Air 15" M2 has no active cooling. The larger aluminum chassis provides marginally better heat dissipation, but sustained professional workloads still cause thermal throttling. The 15" is better suited to lighter creative tasks. Over time, the thermal interface material between chip and chassis degrades.

Warning signs:
  • Sustained tasks taking significantly longer than when new
  • Keyboard and palm rest uncomfortably hot during heavy tasks
  • CPU frequency visibly stepping down in Activity Monitor
  • Battery draining faster than expected during light use

Battery Degradation

The MacBook Air 15" M2 has a larger 66.5 Wh battery than its 13" sibling, providing up to 18 hours of runtime when new. The fanless design means the M2 chip runs warmer during sustained tasks, accelerating battery chemical aging over time. Battery health below 80% triggers macOS service recommendation. Apple typically replaces the battery as part of the top case assembly.
