Just discovered this tool, here some preliminary remarks, hope this helps:
– web interface becomes unresponsive once the download has occured. In order to click on "Bug Tracker" or re-download I had to reload the page
– version 3.0.2 won't launch on MacBook pro latest 13'' generation with Os 10.14
Error message read (loosely translated from french): Impossible to open the application. "QuickHash.app"
