electron-builder: hdiutil error when building for mac

hdiutil outputs an error when building my Electron project. The app is generated and seem to work (tested on two Mac’s with different macOS versions). If I run the hdiutil command manually it doesn’t output anything.

build platform: macOS Sierra 10.12.1 target platform: macOS node: v7.0.0 (also tested on v6.9.1) electron: v1.4.4 electron-builder: 7.14.2

$ DEBUG=electron-builder node_modules/.bin/build -m
