Hi Adam, I managed to do this with python. I have it on my repo here:
https://github.com/danngreen/kicad-mac-builder/tree/set_folder_icon

I don't know where you're at with this issue, and/or the best way to help contribute here (pull request? format-patch?), but let me know if I can do anything more.
BTW Thanks for all your work, this repo really helps osx building!

A PR would be wonderful! Thanks for the kind words.

[danngreen]

Ok, PR done!

We should see if we can do this with the template DMG. I don't want to introduce a Python dependency unless I have to. We may have to copy the contents of KiCad into it the template folder, rather than replace it. I can take a look at this.

Ah, that make sense. It's not like the icon needs to change often, so doing it when preparing the template dmgs seems good.
