  1. Just thought I’d let you know that it appears you haven’t signed the .PKG that’s inside the DMG correctly.

    When attempting to install I’m getting this screen.

    • Same here, getting a “Can’t be opened because it’s from an unidentified developer” error on trying to open the PKG. We don’t want to advise our customers to circumvent core MacOS security features. Please fix!

      • Gatekeeper can be re-enabled after completing the install. Either by changing the setting in System preferences back to App store and recognized 3rd party, or by using the terminal command sudo spctl –master-enable.

    • Make sure your Security is set on Anywhere in System Preferences > Security and Privacy. If you need to disable GateKeeper (the Sceurity setting on 10.12), open Terminal, type sudo spctl –master-disable and hit enter. Enter your admin password, then you should be able to run the installer successfully.

      • Hi dymoeric,
        Thank you for the instructions on how to temporarily disable Gatekeeper to run the Dymo Label installer, then re-enable after installation. We’re aware of how to do this but do not want to do it for a couple reasons:
        – Possibility of human error when re-enabling Gatekeeper after the installation, resulting in the customer leaving their Mac in a less secure state than when they started
        – Additional steps in the installation process mean longer interactions with our customer care team, leading to a poor customer experience

        I look forward to an updated version of the Mac installer that is properly signed and avoids these pitfalls.


        • I agree with Will, this puts us in a tough spot with customers when we have to advise them to circumvent standard security. To make it worse, the issue that this release resolves is a security related issue. I am sensing a significant loss of confidence in Dymo, and consequently my solution, from customers as a result of these issues.

          Please update to a signed version that does not put us as partners in an awkward middle-man position.

        • The updated, signed installer works great! Thank you.


  2. For those of you that had signing issues with the latest release, those issues have been resolved and a new download is available here:


  3. Anyone else running into issues in firefox 54.0.1 (64bit)

    when I have the inspector open and refresh the page at http://labelwriter.com/software/dls/sdk/samples/js/PrintMeThatLabel/pl.html

    I get 10 tries on different ports. safari and chrome are working just fine

  4. Is there a fix for RetrieveInstalledPrinters (mentioned by some people here: http://developers.dymo.com/2017/03/08/the-new-dls-8-6-1-release-is-now-available/)?
