No Stereo Option?

Hi! I’m using a MacBook Pro running Mojave (10.14.6) and Audacity Version 2.2.3. I’m trying to record a Spotify track on Audacity and WikiHow (I know, I know) said it’s best to record in stereo. However, my Audacity does not give me the option to record in stereo. I tried opening the Audacity Preferences, and choosing the “Devices” section on the left, but it didn’t give me the option in the “Recording” panel to change the number of recording channels to “2 (Stereo)”. The device toolbar also does not allow me to change it (see attached image below). Any thoughts gratefully appreciated!

I’m a Windows guy but I see you’ve selected your computers built-in (mono) microphone as your recording device. :wink:
