mac Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

This error typically occurs when the Docker daemon is not running or when the user running Docker does not have sufficient permissions. Here are a few steps to troubleshoot this issue:

1. Check if the Docker daemon is running by executing the following command in the terminal:

   sudo systemctl status docker

If it's not running, try starting it with:

   sudo systemctl start docker

2. Ensure that your user account is added to the `docker` group. Run the following command:

   sudo usermod -aG docker $USER

3. Log out and log back in to apply the group membership changes.

4. Verify that the Docker daemon socket file exists by running:

   ls -l /var/run/docker.sock

5. If the socket file does not exist, try restarting Docker with:

   sudo systemctl restart docker

6. If none of the above steps work, you may need to reinstall Docker.

Please note that the exact steps may vary depending on your operating system and Docker installation method.
