macOS M1: I’m unable to select a network interface from the dropdown menu

The release of DVS 4.2.4.1 should resolve this issue, which can be downloaded from DVS 4.2.4.1

If the issue persists, try a full DVS reinstall through Library/Application Support/Audinate/DVS/Uninstall DVS, then restart the machine, install DVS again, then restart the machine and try running DVS.
