I have an Electron app that has registered a custom url. I checked the box "remember my decision" when I was prompted to open the external application while using Chrome (mac osx).

I now need to have that dialog re-appear.
How would I un-register this url handling?

I've tried deleting the item in the plist as hinted here:

Deleting the line in the plist seems to just regenerate when I launch the app again. I've also attempted changing the version of the app, but that didn't help either.

Has anyone had any luck re-engaging the dialog that asks the user "remember my preference" when opening a custom url handler?

  • Dammit, did they break RCDefaultApp? That gives me yet one more reason to stay on El Cap :/

  • Aye, I agree. I really just need to do this for testing, seems some users don't push the "remember" checkbox and are experiencing some issues. I need to do this to repeat their scenario.

  • Quit chrome

  • Open "~/Library/Application Support/Google/Chrome/Default/Preferences"

  • Search for the "protocol_handler" entry

  • Find the offending app/url. i.e.

  • change to


(Guessing you could also remove)

  • open chrome again and test.
