Handoff/Continuity Feature

Mi Problema

I needed a new airport/Bluetooth Card an bracket.

Mi Solución

It went without any difficulty just as the repair guide in the iFixit page.

Mi Consejo

My advice is that you should not only buy the airport Bluetooth card, also buy the airport/Bluetooth bracket and the Airport/Bluetooth cable. With these you don't have to do any modification to the bracket of your MacBook.
