Hello I have a Sony MZ-N707 I record using a Sony ECM 907 mic, I use a Macbook pro and wish to download my recording from Minidisc to the Macbook , the 707 minidisc has an earpiece output and a lead with a usb output , when I connect to the Macbook the 707 is not coming up as detected . Is there an app or a way I can do this or are the technologies un-adaptable ? thank you
