Tattie Bogle doesn't distinguish between multiple Xbox 360 controllers for Mac OS X El Capitan

Hey everyone, I'm making a 2 player game that uses Xbox 360 controllers on the mac using the Tattie Bogle driver. All the buttons are mapped correctly (joystick 1 is controller 1 and joystick 2 is controller 2) however, when moving the control sticks, controller 1 controls every joystick's axis input (for x and y respectively) regardless of number while controller 2's control sticks are mapped correctly to joystick 2. Has anyone had this problem / know a solution / know of software specific to mac for xbox input? I would really appreciate it I'd hate to see all this work go to waste!
