Carelink macOS High Sierra Workaround

Posted on 12/21/2017 in misc

Medtronic Carelink

This evening I attempted to help my wife upload data from her $9000 insulin pump to the crappy Java driven web app on that she has to use to extract her data from the pump. I was greeted with the error screen above..

Medtronic is blocking the current version of MacOS from even accessing the website, let alone using the crappy Java web app they wrote over 10 years ago to extract data from the pump.

We called the 24-hour helpline, and after navigating past the tier one help desk person that didn't understand "Mac OSX" = Macintosh computer, we got to somebody that was computer literate. She informed us that the website was not compatible with OSX 10.13.2, and she didn't know when it would be. The best she could do was put us on the email list for notification for when all the reporting functions for my wife's $9000 insulin pump wouldn't be crippled.

After fuming for a few minutes I thought of a workaround, and it worked. If you need to get into the crappy Java web app on Carelink and you are using a Mac updated to High Sierra and Safari, this works.

Go into the Preferences Menu in Safari and select the Advanced Tab. At the bottom, you should see the Show Develop Bar in Menu option. Check the box to turn that option on, and close out preferences.

You should now have a new option in the top menu of Safari, called Develop. Click it, and you should see this.

Scroll to the second option, user agent, and select the bottom option of Other on the submenu. Right now, Medtronic is blocking any web browser coming from OSX 10.13.2. So we are going to configure Safari to lie and tell the web server that we are using the older version of OSX.

When you select other you'll get an editable text box that looks like this.

Carelink Error Screen

You should see the text string 10_13_2 in there. All you have to do is change that to 10_12_6 to fool Minimed's web server into thinking you are still on the older version of OSX. After you do that and close out you should be able to use the Carelink web site like normal.

One you are done with Carelink don't forget to go back into Developer / User Agent and select default so that the browser reports accurately again.

Also, don't forget to keep complaining to Medtronic, your Endocrinologist, your Diabetes Educator, and anybody else that will listen about how crappy Carelink is. It's 2017, there is no excuse for insulin pump users to be stuck using such shitty software.

Also, if anybody from Medtronic is reading this, Carelink works fine with OSX 10.13.2, I'm not sure what you people have been doing for the last 12 weeks with the website.

Thank you for posting this and figuring this out! It's nice that I can keep my tech updated and still use the pump. Now if they can get rid of Java completely I may cry! Thank you so much for putting this up!

Totally agree. It's awful.

I couldn't get user agent's 'other' to appear as an option, but I am grateful for the work. My son is 3 with diabetes. Even though tech is advancing, it's not as great as you'd think it should be.

Thanks again

Message: After using the same HP for about 7 years I broke down and bought a new MacBook Pro. Just got the 670g pump so I was so excited Carelink never worked on the HP Finally I could generate some reports Get some info I downloaded the pump info for the first time last week and went to use Carelink again tonight.

You have to put a macbook into unsafe mode for Java to run.

safari->preferences->security->Plug-in Settings,

On the java option hold down the option key while you click the dropdown box for java, you'll see a previously hidden option to run in unsafe mode. Select it and java should work.

You did what Medtronic could not. I have been battling the issue and browser security messages for months. With a brand new pump in hand, it was very important to me and my diabetic educator that I access CareLink. Thank you for your efforts and for sharing this. I hope the Medtronic IT department reads this so they an help their Safari customers.

Many thanks for publishing this post, Chris. My son just got on a new Medtronic pump yesterday, and I needed both the user agent spoofing tip and the secret keyboard shortcut for allowing unsafe mode in Java to get Carelink running on our iMac running OS X High Sierra. Much appreciated!
