Medtronic 670G CGM data upload – resolved

So I recently received my Medtronic 670G pump and the Contour Next Link meter and was attempting my first upload of pump data. Needless to say it didn’t go well (and I am an IT professional).

What won’t work due to changes in Java handling:

  • Chrome on a Mac (didn’t try it on a PC but I suspect it’s the same)
  • Firefox on a Mac (didn’t try it on a PC but I suspect it’s the same)

What did work:

    • Internet Explorer on a Windows 10 PC
    • Safari 11 on a Mac


Uploading Issue:
Every time I run the “upload” function from Carelink, it would tell me that the Java could not be run due to browser restrictions.

At the bottom of the screen, it shows the troubleshooting link ( which gives instructions for Safari 6 and higher but nothing more specific for later editions.

Since my primary machine is a Mac I wanted to get this working. I’m on Mac OS High Sierra 10.13.4 (the latest) with Safari 11.

After calling the helpful (very) Medtronic number, I was guided to the new correct settings to bypass the browser security issue. The solution worked so I suggested they update the help page.

To get it working:
– Safari – Preferences – Websites.
– Highlight Java on the left hand Plugins pane
– Highlight (or add/highlight) on the right pane
– Hold down the alt/option key and click on the Ask/On/Off drop down and select the now visible “Run in Safe Mode” – and uncheck it
– If you only see Ask/On/Off as your drop down options, you’re not holding down the alt/option button on your keyboard…

Once that’s done, stand by for some lovely reports to impress your endocrinologist with.
