On macOS, Bubbles can't be opened just by double clicking on it, because it not code signed

On default installations of macOS, applications can't be run when they are double clicked unless they have been signed with a certificate issued by Apple. The workaround for this is to open the application from the "Open" contextual menu item.

The Bubbles app is not currently signed. It should be.

There is an Electron code signing tutorial that walks though the different options for code signing. It sounds like electron-packager, which we use to build the Bubbles executable, supports code signing out of the box.
