I started the IOT Foundation service following the steps in Jeff Sloyer's tutorial on using a Raspberry Pi, Python, etc. I start the IOT service, and I get the page to Launch Dashboard. However, when I do this, it just spins.
I found the similar question where someone else hit a launch dashboard problem on a MAC where they got it working on another platform, so I tried it from Windows. Windows is working fine. But, I can't get the dashboard from my Mac, which is the laptop I want to work on. The similar question had no resolution, and wouldn't let me add a comment to it, hence a new question.
