Connection Problem

[anmeva1]

Hi, I am trying to test this project in my Mac OSX, but once
it is connected and all installed, I cannot see anything in the Gameview or in the glasses.
What's more, this error appears in the log:
DllNotFoundException: LeapC
LeapInternal.Connection.Start (LeapInternal.LEAP_CONNECTION_CONFIG config) (at Assets/Plugins/LeapMotion/Core/Plugins/LeapCSharp/Connection.cs:161)
LeapInternal.Connection.Start (System.Boolean multiDeviceAware) (at Assets/Plugins/LeapMotion/Core/Plugins/LeapCSharp/Connection.cs:152)
Leap.Controller..ctor (System.Int32 connectionKey, System.Boolean supportsMultipleDevices) (at Assets/Plugins/LeapMotion/Core/Plugins/LeapCSharp/Controller.cs:389)
Leap.Controller..ctor (System.Boolean supportsMultipleDevices) (at Assets/Plugins/LeapMotion/Core/Plugins/LeapCSharp/Controller.cs:365

May you be able to tell me how to solve it? I am using Unity 2018.4 LTS.
Best regards,
Andres
