Hi @RobR and sorry to hear you are having issues installing the Joulescope software on Mac. Have you tried holding the control key while clicking on the Joulescope software? You should then allow you to select “Open” , which then shows a dialog where you can select Open:
I don’t believe that the Joulescope software has changed with regards to Mac distribution since 0.6.8, but Apple has certainly adjusted their policies. We still have the action to ensure that the Joulescope UI software can be distributed more seamlessly on Mac.
