I have a number of repeating events in Calendar (formerly iCal).

I often make changes to individual ones on-the-go, but every time it asks me this:

enter image description here

How can I make the default behaviour change a single event without that dialog appearing?

I suspect there could be a Terminal command I can run.

BONUS: Then, if I want to edit the series, can I still use the Get Info interface?

    Interesting idea. You want to basically never be asked to change all future events? (or are you proposing a script that could automate severing one instance of a repeating event, saving the details and then making a stand alone instance that's not part of the recurring pattern?)

Unfortunately it cannot be settled up using CLI settings

defaults read com.apple.iCal

have no option to change default behaviour. But you can find useful a scripting with AppleScript
