Definition: The butterfly keyboard is Apple’s ultra-low-travel keyboard mechanism used in MacBook Pro (2016–2019) and MacBook (12″ 2015–2019). Named for the butterfly-shaped key mechanism, it was designed to be thinner than traditional scissor-switch keyboards. The butterfly mechanism had a significantly higher failure rate than other laptop keyboards — individual keys would stick, stop registering, or repeat unintentionally, often caused by a single dust particle. Apple replaced it with a scissor-switch mechanism on MacBook Pro 2020 and all subsequent models.
Why it matters for MacBook repair
The butterfly keyboard is the most notorious MacBook keyboard issue of the past decade. Apple’s free Keyboard Service Program ended in 2024. Repair now falls to third-party specialists. Critically: the keyboard is integrated into the top case assembly — the same unit that contains the battery and trackpad. Replacing the keyboard means replacing the entire top case, including the battery. For standard laptop keyboard faults on Windows laptops, see our laptop keyboard repair service.
