Does anyone know how to remove devices from this list that you no longer use? For example, I wanted to start from scratch on my new MacBook Air, so I reformatted the laptop. Now, on my iPhone 6+, I see Macbook Air and MacBook Air (1). If I format again, I see MacBook Air (2), even though it's still the same Macbook. Any way to delete or edit this list in any way? Or am I stuck with (1), (2), etc forever?
