Nintendo games are only available on their proprietary gaming hardware (not the Mac). Their flagship console right now is the Nintendo Switch. The Nintendo 3DS is a slightly less inexpensive option, but is supposed to go out of support this year, meaning there won't be many new games from Nintendo on that system.
I would recommend a Nintendo Switch and Legend of Zelda: Breath of the Wild. Both can be purchased at any major retailer (Best Buy, Walmart, Amazon, Target, etc.)
Also, if you have any iOS devices, Nintendo released some mobile versions of a few of their major franchises: Super Mario Run, Animal Crossing: Pocket Camp, and Fire Emblem Heroes, though I don't think any of these are necessarily a good representation of the quality of the software they put out on their own platforms.
