I have 10-20 old mono cassette tapes with personal family stuff on them. I can easily play them on a couple of old cassette players. Both players have output ports using 3.5mm connectors. My MacBook Air obviously has a 3.5mm port that is used for BOTH input and output.
When I connect the two devices and go to System Preferences -> Sound -> input (to capture the signal from the cassette player)… nothing shows up.
I’m, obviously, doing something wrong. I thought this would be a fairly common question for people over 40.
Thanks in advance for any assistance.
