Add (yak) Private Server Programmatically?

Can anyone recommend code to modify/set the Yak private server settings on MacOS?

Why I ask: I’m trying to make it as simple and foolproof to add our company’s local package server when ppl set up rhino. I have a working solution for Windows that directly edits the XML doc where package settings are stored, but I haven’t found a comparable strategy for the MacOS side yet. I’m pretty sure it’s hiding somewhere in the com.mcneel.rhinoceros.7.plist file, but I haven’t found it (and don’t have a strategy for modifying it yet either).

I’m aware of current documentation for adding private Yak servers, but doing it manually is error prone - it would be much easier to roll out to my team(especially to new rhino users) if it was scriptable. Thanks!
