Works great. I didn't need to install any software to use this. Running Catalina 10.15.5. My MacBook Pro would not let me select "Stereo Line-In" from the headphone/mic combo jack. Or digital audio from the internal "mixer” bus. In Audacity it just showed the "built-in microphone". as input. Audacity recognizes this V.TOP device as a stereo input source (PnP audio device). I could record audio from any website and save it in just about any audio format imaginable. If you're hearing it through your Mac's headphone jack, you can leave the headphone jack and go back to the USB port. Audacity will record it. If you need to "control" the audio during recording, simply run analog audio through the mixer (in/out) and use the headphone jack on the mixer to hear it. I understand that the digital/analogue/digital conversion isn't the best way BUT - I'm 74 years old and I still can't hear the difference!
