I bought these rudder pedals from Thrustmaster, together with a Hotas (T.Flight Hotas X), also from Thrustmaster, to get cheap and suitable hardware on my Mac for the helicopter flight simulation with x-plane 11 beta.
Works flawlessly. I can only recommend it. No driver installation required. Perfectly recognised and supported by x-plane. Just has to be adjusted to the requirements, but this is child's play thanks to the graphic display of both controllers.

As I own neither a Mac nor X-Plane I cannot answer the question
