Shearwater Desktop Certificate Issues


For users running into certificate problems (shown above) when updating Shearwater Desktop on Mac, we have resolved the issue with a new installer.

For those who may have visited this page earlier, we have removed the previous instructions as they are no longer needed.

How to resolve:

  1. Start Shearwater Desktop. A message inviting you to update will appear.
  2. Click "update".  After the update finishes loading, you will see a traditional Mac style install folder with the Applications folder and the Shearwater Research folder.
  3. Close Shearwater Desktop.
  4. In the installer folder, drag the Shearwater Research folder onto the Applications folder.
  5. You may get a pop up asking if you want to overwrite the old version. Select Ok.

That's it! you can now start Shearwater Desktop from the Applications folder in Finder.

If your copy of Shearwater Desktop is not currently functioning, please visit to download the installer, then follow the rest of the instructions outlined above.

If you continue to run into any issues please feel free to email us at

  1. I have followed these instruction to upgrade to 3.0.8 on OSX Sierra. The application installs and now simply won’t launch. I’ve gone from old desktop version to one that won’t open and i can’t download my dive data.

    • I have followed the instruction to install the Shearwater Desktop on my MAC. The application installs and won’t launch.

      I also just bought two Perdix AI’s, is there a location on your website to register the computers

  2. I’m in France
    It’s impossible to connect my Perdix since i’ve sierra on my MAC.

    What can i do please


  3. Same issue for me on macOS 10.12.2. I had the certificate error initially so I deleted and reinstalled the application. It seems to have installed fine (if I try to reinstall again, it tells me the same version is already installed) but won’t launch. No obvious crash or error message. Adobe AIR version is, which I believe is the latest update.

  4. Mac

    Same issue, I can get it to install on Mac 10.12.2 but app won’t start. Surprised I don’t see a response from Shearwater here yet.

      • I believe at last I have managed to connect my new MacBook Air with OS Sierra 10.12.2 software. However, I cannot for the life of me get the Mac and the shearwater petrel 2 to communicate. I have checked and double checked the bluetooth is turned on and the Mac is picking up all other bluetooth devices but not the Petrel. I have initiated the log download but all I seem to get on the Mac is “Error 190# Scan for dive comupter failed”.

        I have tried turning the Mac Off and back On again but still nothing.

        Please help

  5. I also have had som issues with upgrading and downloading Dive log. I have not tried to do a fresh install as I didn’t´t want to have same problems as Mike stated on 4th december…

    “I have followed these instruction to upgrade to 3.0.8 on OSX Sierra. The application installs and now simply won’t launch. I’ve gone from old desktop version to one that won’t open and i can’t download my dive data”

    I run Shearwater Desktop v.2.5.0 with macOS Sierra v.10.12.2 and wonder if the issues mentioned before by others are solved?

    Kind Regards


  6. one step is missing in Certificate error instructions, After you put the previous Shearwater desktop program in the trash empty trash and restart computer then try installing the new desktop app it worked for me

  7. I have just spent over three hours following instructions trying to update my Perdix via the update to Desktop 3.0.8. I have followed your instructions (repeatedly) to install and reinstall Shearwater Desktop and/or Adobe Air on my Mac running OSX Sierra. Long and short of it is that my Perdix no longer links with the Desktop. Having followed your online instructions to reinstall Adobe Air that has not resolved the issue and has in fact made it worse as Desktop 3.0.8 now refuses to run at all. I have emailed on this issue previously and the solution given was to follow the instructions on the website to remedy the problem. THOSE INSTRUCTIONS DO NOT REMEDY THE PROBLEM. I now have a Perdix computer that I can’t update and a Shearwater Desktop 3.0.8 that refuses to open and sync with the computer itself.
    Guys, you really need to sort this out…..

  8. Hi – is there an update to this issue? I am reluctant to delete my earlier version until I know there is a working fix running a mac os sierra 10.12.3 and a perdix…

    • Unfortunately this will always be a problem for 3.0.8. Mac is only unfriendly with the installer so the application still runs as expected.

      Contact us at: we can guide your through these steps.

  9. HI! I’m running El Capitan ver.10.11.6 (15G1212), I nstalled teh Shearwater desktop to thry and sync my perdixAI but the desktop is not reciogininsing the the dive comp, in fact I cant even see the dive comp register in the blue tooth function window of my computer.

  10. Hi Guys,

    i am running Mac Desktop sw 2.5.6
    I want tot update to latest version 3.1.0 but read the latest errors with installer and get the same du etc insecure or different license and signature.

    My Mac is 10.12.3 OS Sierra

    Means it is not a installer problem – more a developer and official signature problem by shearwater.
    Times and rules have changed at MS and Apple. Only sw with official signature will be accepted.
    More detailed will be found at Apple etc.

    How do you help me now?

  13. I was excited to get my new prefix AI to compliment my petrel (1). I have a MAC and the latter OS as well as have updated the Shearwater desktop to the latest version. My Petrel upgraded to v44 firmware however the Perdix AI is not being recognized by the Bluetooth of my MAC. the Perdix AI SN 3808E8E9; Firmware v40/AI03; hardware AI-02A.

    Any suggestions?
