Docker for Mac locks up / fails to install

Docker Desktop for Mac
1

I’m trying to install Docker for Mac on Mac OS Sierra 10.12.1.

After download Docker for Mac, dropping the Docker.app in /Applications, and opening it… nothing happens.

The app appears to be running:
ps ax|grep -i docker
712 ?? S 0:00.13 /Applications/Docker.app/Contents/MacOS/Docker -psn_0_340051
809 s000 S+ 0:00.00 grep -i docker

But no icon appears in the command bar. No links for docker show up in /usr/local/bin:

ls -l /usr/local/bin/dock*
ls: /usr/local/bin/dock*: No such file or directory

And about the only thing I can try is to kill the Docker.app and run it from the command line, but this is not at all revealing either:

511 zbeckman:~$ /Applications/Docker.app/Contents/MacOS/Docker --help
INFO : KSCrash.m (343): -[KSCrash sendAllReportsWithCompletion:]: Sending 0 crash reports
kern.hv_support: 1

And… nothing.

Ideas?

And, when I try docker-diagnose (from the app package), I get this:
