Install Docker on Mac runners

I have to add this code for Mac runners when I need Docker to be available:

HOMEBREW_NO_AUTO_UPDATE=1 brew install --cask docker
sudo /Applications/Docker.app/Contents/MacOS/Docker --unattended --install-privileged-components
open -a /Applications/Docker.app --args --unattended --accept-license
echo "We are waiting for Docker to be up and running. It can take over 2 minutes..."
while ! /Applications/Docker.app/Contents/Resources/bin/docker info &>/dev/null; do sleep 1; done

It takes a lot of time. Would you be able to install it by default? Thanks.

@armenzg I use your code to run Docker in Mac, it works most of the time. However, it sometimes fails with this error:

Run brew install --cask docker
  brew install --cask docker
  sudo /Applications/Docker.app/Contents/MacOS/Docker --unattended --install-privileged-components
  open -a /Applications/Docker.app --args --unattended --accept-license
  echo "We are waiting for Docker to be up and running. It can take over 2 minutes..."
  while ! /Applications/Docker.app/Contents/Resources/bin/docker info &>/dev/null; do sleep 1; done
  shell: /bin/bash -e {0}

Any idea how I can prevent that error?

Here is the closed issue for the addition of colima: https://github.com/actions/runner-images/issues/6216.

You can also check the environment description for macos-latest runners (which is currently macOS 12).
