Actual behavior

OS X 10.11; fresh install won’t respond to docker commands. My laptop works fine. Tried reset and uninstalling to no avail.

Perhaps this is related to networking being broken.

docker:~# ping 8.8.8.8

Enabling VPN compatibility mode fixed it for me. Looks like something is funky with its network.
