docker for mac failed to start
<p>My docker for mac (1.12) setup has been working for a while now. All of a sudden, the daemon is not starting anymore - I think it happened after the Mac went to sleep and came out again - not sure.</p>

<p>Restarting the mac didn't solve the problem either. The whale icon at the top just keeps being animated. Below is what the diagnostic says. </p>

<p>I'll do a factory reset if needed but fear that I'll lost track of the storage that's been currently used by my images/containers.</p>
