I am being interrupted multiple times a day by a mysterious dialog box that says:

"OS X 10.13 is not supported. There is an update but you are on OS X 10.13 or an earlier version. Upgrade to the latest version of macOS to install it."

While I was considering doing the OS update soon, this dialog has actually caused me to hesitate, because I can find absolutely no documentation for it. A google search gives only a single hit, and that is in French. I am a bit concerned that this could be evidence of malware- perhaps, for example, the running an update could give malware a special opportunity to get extra permissions/control of my system.

Does anyone have an idea where such a dialog could be coming from, or what app may be triggering it? Image attached.

Recurring, unexplained dialog box

Update: here is the one (french) link I found on the internet which may reference the same dialog box. No useful information there, as far as I can tell:


  • Can you add the link to the page you found via Google? Did you check whether one of your applications or login items needs to be updated?

    Something you are running in the background needs to be updated. To confirm, boot into Safe Mode (hold Shift while booting). If it goes away, it's a 3rd party app that needs to be updated.

    Confirm what? A dialog box is real? A notification doesn't have to be generated by macOS to be genuine; any app can create a notification. In this case an app could be complaining that it's no longer compatible with the OS you're running.

    Problem solved! It was a 3rd party app (Docker), installed as part of a different application suite. Oddly, the app preferences had it set to run upon login, but I didn't find Docker listed in the Sys Pref Users and Groups/login items. Anyway, thanks for your thoughtful comments. Nov 7 '20 at 15:59

    @ChuckSindelar Thanks! I was also wondering what that was. I'm able to confirm it's Docker by manually doing 'Check for updates...'. They really should have included their app name in that message.. Nov 11 '20 at 12:33

The problem is with the docker application.

    Confirmed - when I force quit Docker from the Activity Monitor, the prompt goes away.

This comes from Docker. Click the docker icon in the bar and choose Preferences. Uncheck Automatically check for updates. Click Apply & Restart. It should go away after changing this setting.

    Thanks. This seemed to solve it for me. Jan 25 at 18:21

    Note that turning off Automatically check for updates does not work in all cases (including mine). See this issue in the Docker for Mac GitHub. Apr 10 at 19:12
  • There is no "Automatically check for updates" in Docker for Mac v3.0.3 unfortunately Jun 9 at 16:08
