What compatibility and safety notes should I keep in mind?

This replacement is intended specifically for the MacBook Pro 13‑inch models produced between mid‑2009 and 2012.

• Double‑check part numbers such as 661‑5229, 661‑5557, 020‑6547‑A before purchase.
• Not for A1278 2008, A1321, or A1286 models — verify serial/model first.
