It sounds like you should just stop being bad at teaching your team members.

If an individual is unable to figure out how to show dotfiles in Finder on MacOS do you really want them making commits?

In windows and Linux you can still open hidden folders and files simply by typing the hidden path element into the file manager. You still won't see any hidden contents, but you don't need to type out the full path--just navigate to your user folder, and type `./.config` in it to enter it.
