recording from an old cassette deck onto a mac mini
I have a few old tapes which I want to save digitally. I have an aux cord connected to a USB which is then connected to my Mac mini. When I press "play" on the cassette tape, the computer is detecting something but I can't hear anything. (when I go System Settings - Sound - Input... it shows movement). A) how can I hear anything. B) How do I record/save it?
Thanks
