Docker for Mac froze and will not start properly after timeout on `docker ps -a`

Expected behavior

Docker should start normally

Actual behavior

Docker stays in "Starting state



Docker for Mac: version: win-v1.12.0-beta19
OS X: version 10.10.5 (build: 14F1808)
logs: /tmp/20160716-223951.tar.gz
failure: docker ps failed: Failure(“docker ps: timeout after 10.00s”)

  • the output of:

    • Moby Menu > Diagnose & Feedback on OSX
      The error said that command docker ps -a failed to respond, and it was a timeout error.
  • host distribution and version ( OSX 10.10.x, OSX 10.11.x, Windows, etc )
    OSX 10.10.5

Steps to reproduce the behavior

When Docker for Mac crashed it was due to me running docker ps -a and it hung. I quit docker and brought it back up, and it now just stays in “Starting” and never actually starts.

I restarted the machine and I get the same behavior when I try to launch Docker for Mac.

I want to note that I was able to restore Docker for Mac to its defaults through the menu options, and that allowed it to start normally. I then had to adjust my settings back to where they were.
