With Mojave, Apple made it very difficult to distribute applications without going through the Apple Store. Here is what you can do to install and run the Joulescope UI:
- Download the Joulescope UI
- Open the download and drag joulescope.app to Applications
- Control-click, select Eject “Joulescope”.
- Open Finder and navigate to Applications
- Hold control, click on joulescope.
- Select Open
- A window will pop up. Click ok. The window goes away.
- Hold control, click on joulescope
- Select Open
- You will now see the same window, but now with an “Open” option. Click Open.
- But nothing will happen.
- However, you should now be able to run the Joulescope UI normally by double-clicking on it or clicking on it in the bottom bar.
