Handoff/Continuity Feature

我的问题

I needed a new airport/Bluetooth Card an bracket.

我的修理方法

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

我的建议

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.
