Dance pad isn’t detected on my Mac
A short list of hints which can help troubleshoot the issue with detection of dance pad.
Here’s what this article covers:
Verify if the cable is placed correctly
By far the most common issue is that the cable isn't pluged with the dance mat properly. Try to insert the cable into the dance mat once again. Please make sure that the slanted part of the plug is upwards - in the same position as in the picture.
When connecting the cable to the dance mat you should feel click under your fingers. If you do, the plug is placed properly in the socket.
