  • 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.

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.
