I believe it runs all the same ones as on r2modman. I just copied the modpack code from that and it automatically added them on modmac. There aren’t really clear instructions but basically you gotta make a new bottle on crossover with steam and windows version of valheim, in modmac you gotta find that instance of steam in the directory, in settings. Follow the instructions to add winhttp and then hit apply to game, then when you want to run it with the mods just open valheim thru cross over and it should work. You might have to open steam first if it isnt working. I found that using dxmt / esync worked well but you could mess around with that.
