Updating Retroarch for MacOS

I have fully configured Retroarch 1.9.0 on my Mac, but when I download the latest 1.9.1 and launch it, I see that everything reverts to a generic configuration.

I saw that support files are stored in Library/Application Support, but it appears that all the downloadable content like cores and shaders etc. gets stored directly inside the app.

The point I am getting at: is there a simple way to download a newer version of the Retroarch app and then just drag across content from the old app, so that I do not have to download all the content again and then manually re-configure the settings? I tried a simple drag and drop but it did not work.
