The Dexcom / Mac Dance.

Sharing, because that’s what friends do.

Brian Bosh, living with type 1 diabetes and also apparently a very clever guy, found a workaround for uploading Dexcom G4 data to a Mac computer. Yes, you read that correctly.

“I created Chromadex because I was trying #DIYPS but hated carrying around a second phone. I figured I was close enough to a computer enough of the time that I could run an uploader on there and it would work well enough. There already is an uploader for Windows and Android, but no way to do it on the Mac. (Or Linux for that matter.) Once the uploader was built, though, I thought it really ought to do some of the same things Dexcom Studio did, since that’s not available on Mac either: If I had the data, I might as well offer their reports too. At this point it will upload to #DIYPS, NightScout and run three reports. It still takes a little bit of wrenching to get it to upload and I’d like to make that easier. Had a few people ask if I could make it work with MMOL. I’d like to get more reports working.”

I haven’t downloaded my data yet via this application, but others have:

If you want to try it for yourself, visit the Chrome web store and download Chromadex for free. And if you like how it works, please thank Brian.

    Have a nice day.

    • At first glance, I thought you wrote “Thanks for sharing this, my tweet.” Thought it was a term of endearment. 🙂

    Wow–this is brilliant. I might actually download my own data more than every 4-5 months. For others who try this–I had a little trouble initially after downloading. The problem resolved by hitting reset (deleting all the downloaded data) and then downloading again. Thank you Kerri, Chris, and Brian!

    Love this idea, I’ve been grumbling at Dexcom for 2 years about their lack of Mac integration (on basically every level)… I can’t even use an old Windows laptop to get my daughters reports! I’m still working on trying to get this cool little app to work (it seems to want to say it’s downloading but nothing happens) but as soon as I can figure it out this is a GREAT great thing – thank you so very much for sharing!!

    I can’t wait until someone creates a phone app for this. Or until the receiver is built into a phone app!

    • There’s potential there. It doesn’t work — yet — but on certain Android phones it could become possible. Of course any phone that could eventually become possible can ALREADY do it with the Android Uploader ( ).

      This stuff is still moving fast 🙂

    Thanks for sharing this! Maybe I’m just not tech savvy enough, but after downloading chrome, then downloading the app, then creating an account in MongoLab which is required to run the app, apparently, it still isn’t working for me.

    Hoping it works on a day when I have the patience to try again!

    • Hi Alana- hit me up on Twitter of FB for more support, but…
      You don’t need Mongolab. That’s just for Nightscout integration. Plug in Dex, start app, press download all, and in a couple minutes try grabbing a report.

      Note it won’t work at all on old versions of OSX. Sucks but I just don’t have any old Macs to test and troubleshoot against.

    Great that you made the dexcom now somewhat compatible with Mac!
    I just can’t manage to export the data properly.. it just turns out as a large list of numbers which I do not recognize as bloodsugers..

    Another option for those people on a Ping pump is to use the service. My Animas rep walked me through how to use the Diasend uploader on my Mac to upload from my Dexcom G4. Here are the steps and the sequence does matter.

    1. Subscribe to Diasend.
    2. Download the Mac version of their uploader.
    3. Open the uploader. It must be open on the desktop.
    4. Plug the micro USB for your G4 into the G4.
    5. Now plug the USB cable into the Mac.
    6. The uploader will now be able to recognize the G4.
    7. The first time you will need to authorize the G4 for your Diasend account.
    8. Once the data is uploaded, then click the quit and go to Diasend option.
    9. Your CGM will now be available for you and your healthcare team.

    I particularly like this setup because it puts both my pump, standard glucometer and CGM data into a single report.

    With both Nightscout and Diasend, I now have a decent set of analysis tools at my disposal that are Mac friendly.
