iMessage and FaceTime on MacBook Air 2018
I use the same Apple ID on both my MacBook and iPhone. iMessage and FaceTime works fine on the phone. But when I try messaging or calling the same number on my MacBook, it says the number is not registered. And also, when I choose my MacBook from the speaker option while talking to somebody on the phone, I don't hear anything from my MacBook.
