TypeError: error setting argument 2 - writeInt64: Number/String 64-bit value required

[Nicolas Surleraux]

This is caused by the Cocoa example in this repo.

Code causing the error : app('setActivationPolicy', $.NSApplicationActivationPolicyRegular)

/Users/nsurleraux/Documents/test-cocoa/node_modules/nodobjc/lib/class.js:193
      else throw e;

did you get a result on this?
For me, app works on el capitan, (build against 6.9.5 on el capitan), but not on Majave (same 6.9.5 node).

this solved it for me:
$.import('AppKit');
$.import('Foundation');
$.import('Cocoa');

seems the last one is not enough.
