On my mac i find it under users/kristoffer/dominions3/mods
That's the standard Mac location. It is "next to" your saved games folder. You may need to create the "mods" folder if it doesn't already exist. Same thing for a "maps" folder for custom maps.
Thank you! The location was exactly where djo and Kristoffer said it was. All is working fine now. Oddly, the maps work in both locations and mods don't. This is very different from the PC OS.
