How do I fix this EasyAR Unity Graphics API Error?

Getting the following error on my MacBook Air 15 using Unity 2019.1.7f1:

I tried changing some graphics api settings to OpenGL and Metal but didn’t work.

EasyAR is running with an unsupported graphics API of type -16
UnityEngine.Debug:LogWarning(Object)
EasyAR.ARCameraBaseBehaviour:Update()

Thank you for the response! I’ll look into it.
