Failed to initialize vuforia unity

INIT ERROR is displayed when I try to build & run my unity project on Vuzix m300.
I have one simple image target and a sphere on it to test if it runs successfully, when I play in Unity it acts as expected, but when I run it on Vuzix m300 it displays INIT ERROR.
I am running Unity on Mac OS.
Any possibilities to fix this issue? Please let me know, I am really stuck.

After some time passed it got fixed automatically.
