Docker really messed up with the documentation here.
I can confirm that after you successfully install and get the UI not starting running the following commands to copy back the files that the guide tells you to delete (and conventiently doesn’t tell you to replace)
sudo cp /Applications/Docker.app/Contents/Library/LaunchServices/com.docker.vmnetd /Library/PrivilegedHelperTools/
sudo cp /Applications/Docker.app/Contents/MacOS/com.docker.socket /Library/PrivilegedHelperTools/
