I really love the Natural Color reshade and can't stand the yellow tone of the vanilla game. Unfortunately, I only have a mac and that reshade doesn't work on mac. I doubt anyone knows how to make that mod work for mac, but that would be the ideal solution for me. Otherwise, does anyone know of any alternatives that work for mac? Maybe textures? Although I would like to avoid those. I would appreciate any kind of help.
SgtPickles, the author of MTN, has been working on a SMAPI based reshader system. It's not ready yet, but that will probably be the best bet! Otherwise you can try a recolor like Eemie's or Starblue. There's several more out there as well.
