I have installed docker for mac on my machine. I have pulled a repo from the docker hub, the docker run command includes the docker-machine ip parameter for which I get an error, Error: No machine name(s) specified and no "default" machine exist. Could someone elaborate the difference between docker machine and docker for mac.

Docker Desktop is an easy-to-install application for your Mac, Linux, or Windows environment that enables you to build and share containerized applications and microservices.
Docker Engine accepts docker commands from the CLI, such as docker run <image>, docker ps to list running containers,docker image ls to list images, and so on. Docker Machine is a tool for provisioning and managing your Dockerized hosts (hosts with Docker Engine on them).
Docker itself “uses the Linux kernel and features of the kernel, like Cgroups and namespaces, to segregate processes so they can run independently”. On MacOS, Docker is run using a Linux Virtual Machine and relies on sub-components: HyperKit, VPNKit, and DataKit to support its functionalities.
If you have Docker for Mac running on your machine, you don't need Docker Machine. Using Docker Machine (usually through Docker Toolbox) to run locally only if you have an older Mac version that isn't supported, which isn't the case here, or a Windows machine without Windows 10 pro.
The only other case you need Docker Machine is for controlling remote machines or setting up multiple nodes locally.
