I have na old macbook pro that will not even turn on anymore because its overloaded w saved data, I was told by teh apple store I can caonnect my old macbook pro to my new mac air essentially turning the macbook pro into a hard drive.
What connections do I need to connect the two?
The macbook pro is around 10 years old and the air is brand new.
MacBook Pro 13″, macOS 10.13
