Answer 2

I am also having a similar issue, and wanted to force quit the app, so I tried cmd + options + esc, but couldn't find the app in the options.

I finally solved the issue by killing the docker process using Activity Monitor.

Steps:

1. Search for activity monitor by pressing (cmd + space), start typing activity monitor, then hit enter
2. Go to search bar and type docker, you will see the docker process in red with (not responding)
3. Double click on the docker process
4. Click Quit and select Force quit.

Answer 3

I fixed it by removing Setting.json code from my local pc

$ pwd
$ cd ~/Library/Group\ Containers/

Group Containers$ ls -la | grep "group.com.docker"
Group Containers$ group.com.docker

Group Containers$ cd group.com.docker
group.com.docker $ cat settings.json

Group Containers $ rm -rf group.com.docker

Now run it again.
