Following the OS version compatibility with Pro Tools 12 I wanted to downgrade the OS to Sierra 10.12 but luckily I failed to do so (my bootable version of Sierra was not booting). So I kept on forcing the 003R to work with High Sierra. You can see the result in the attached image. Check if there is nothing blocked in the "Security & Privacy" tab in the System Preferences. Good luck
