Information

  • Mac OSX Version: 10.11.5 running on MacBook Pro (Retina, 13-inch, Late 2013)

  • Docker version: Docker 1.11.1-beta12 is currently the newest version available.

  • Output from sudo opensnoop :

Steps to reproduce the behavior

  1. Make sure Docker icon is present in menu bar.
  2. Open Terminal.app and issue command sudo opensnoop. Wait a few seconds and you’ll see that message come over and over again.

Saw this as well, can we just get an explanation to why this is required?
