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

Damn. I’ve been running the build on my work computer which has AVG AntiVirus installed… The realtime protection caused the problem, now the build runs fine. Thanks again @develar.

Got the error with Sophos too, works properly by deactivate it
