I'm targeting macOS darwin:x64.

However, running electron-packager succeeds with

$ electron-packager /Users/USER/electron-node-red Monitor --icon /Users/USER/Logos/All.icns Packaging app for platform darwin x64 using electron v2.0.18 Wrote new app to /Users/USER/Monitor-darwin-x64

This issue has been reported earlier at https://github.com/electron/electron-packager/issues/639 and https://github.com/electron/electron-packager/issues/503

Any hint? Thank you!
