When selecting a Focusrite interface as the input and output device in System Preferences > Sound on a Mac, a message stating 'This device has no input/output controls' will be displayed at the bottom of the screen for both tabs:
This message does not mean that there is an issue with your audio interface. It is a reminder that the Mac computer doesn't control the signals coming in and out from audio interfaces. Your Mac will not be able to raise or lower signals when an audio interface is set as the primary device in System Preferences under Sound.
All signals going in and coming out are controlled by the Focusrite hardware directly.
In addition to this, the speaker icon in the Menu Bar will be greyed out if you have this icon enabled and visible.
If you are having issues with your software on the Mac not receiving input signal from your audio interface, or you can't hear audio via headphones/speakers connected to your audio interface, then it could be caused by other things.
