Cannot run Leap Motion Unity Asset on Mac

[kenzieshaw0114]

Hello,

I just downloaded and installed Leap Motion SDK v2.3.1, unity core assets 4.3.4, and my unity version is 2017.3

However, when I tried to play a demo scene in the leap motion assets, I got the problem.
"An application is requesting features not available in this version of the Leap Motion service. Please instal..."

What can I do to solve this issue?

Thank you.

Unity Core Assets 4.X require the Orion tracking software (i.e. 3.X).
