In the Resolve preferences, in the System tab, under Video and Audio I/O:
If the interface is selected as the default audio interface for the Mac, you can set Speaker Configuration to Use System Setting. Otherwise, set it to Manual and make sure "Device" is set to your audio interface. In my case, it is a Behringer UMC1820 (a bit bigger than what is needed for ADR work but I have it for other reasons), and it is the default audio interface on the Mac, so I am using "system settings".
On the Fairlight tab, add a Mono track, open the ADR panel, and switch to the "Setup" tab of that panel. Select the desired track as the "Record Track", then select the intended input as the "Record Source" - this should be one of the inputs from your audio interface.
The track should automatically be armed for recording.
In the List tab of the ADR panel, add cues that need to be replaced using ADR. In the Record tab, select a cue and use the controls at the top to record.
Note that the list of available inputs includes inputs from multiple sources, including the built-in audio inputs of the computer, and those of the interface, which for some interfaces might not have names associated with them and thus may simply show up as the input channel number with an empty name after them - this won't prevent them from working.
