I don’t use the products that currently benefit from the Nik Collection. I used Apple Aperture from the beginning. (Actually it still runs on Mojave - go figure,) The Apple Photos app is sufficient for my needs presently and with powerful extensions it is pretty sweet. The older free Nik Collection works fine but I like to keep my software up to date. Do you plan to release a version of the Collection for Apple Photos?
Thanks for considering!
