Update needed from Audacity?

Trying to use the Super USB Cassette Capture and Audacity is only giving me an option to record from my mac microphone. I thought maybe I got the wrong version so I downloaded again (dmg) whatever that means and now it says that Audacity needs to be updated to work with my version of Mac. Any ideas ?

The current version of Audacity is 2.4.2. It is available via the Audacity website: https://www.audacityteam.org/download/mac/
