tl;dr: I want to automatically open certain app links, such as Zoom meeting or Mac App Store links, without being prompted to confirm first.

I recently replaced my MacBook, and Google Chrome behaves differently on my new one when opening app links, e.g., Zoom.us: it no longer offers the option to "Always open these types of links in the associated app".


Before (checkbox)


After (no checkbox)

I don't know what version of Chrome I was running before (though I'm pretty sure it was up-to-date at the time--a couple of weeks ago). I use Chrome Sync, so my extensions and settings should be substantially the same.

Is there a way to get back the previous functionality and make Chrome open certain apps automatically without prompting for confirmation?

Tried and tested technique for macOS:

  1. Have Chrome version > 79
  2. Run the following command in terminal ​

    ​defaults write com.google.Chrome ExternalProtocolDialogShowAlwaysOpenCheckbox -bool true
  3. Quit Chrome

  4. Restart Chrome

As of Chrome 79, you can edit use a custom policy to get this behavior back: https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ExternalProtocolDialogShowAlwaysOpenCheckbox

@abhishek-ranjan answer provides the way to do it on macOS.

On Windows:

  1. Open regedit
  2. Either under HKEY_LOCAL_MACHINE (for everyone using the computer) or HKEY_CURRENT_USER (only the current user), create the following key(s) as necessary: Software\Policies\Google\Chrome
  3. Create a REG_DWORD named ExternalProtocolDialogShowAlwaysOpenCheckbox and set the value to 1
  4. Restart Chrome

If you want a regedit script to do this, see https://bugs.chromium.org/p/chromium/issues/detail?id=1013598#c24


It is a known "bug" but at the same time it's not a bug it really is a security feature Google rolled out. https://bugs.chromium.org/p/chromium/issues/detail?id=982341
