Hi oscarnmejia,
You do not need to install anything. Plugins have to be placed in X-plane plugins folder :
X-Plane 11\Resources\plugins\G1000BridgeX-mac-1.5
You then just need to launch X-plane. This one requires a manual connection but the steps are well described in the PFD settings (tap the top right corner of the Ipad when PDF app is running), Sim Connection tab.
Note that the computer running X-plane and the Ipad must be connected to the same local network.
