Thanks for figuring that out. I think we have tons of info in the Readme right now that would probably fit better in a wiki. I'll figure out if we should use wiki.parity.io (there's a FAQ for Fether) or if we should use github's wiki |

This is a known macOS issue on Mojave 10.14 and only happens in development environment when running an Electron app. It was necessary to go to System Preferences > Security & Privacy > Privacy > Camera, and ensure that the checkbox for the "Terminal" app is checked. See electron/electron#14801 (comment) |
