To install Minikube for Mac or Windows, navigate to the following link at https://kubernetes.io/docs/tasks/tools/install-minikube/.
Follow the instructions carefully. If you have the Docker Toolbox installed, then you already have a hypervisor on your system since the Docker Toolbox installer also installed VirtualBox. Otherwise, I recommend that you install VirtualBox first.
If you have Docker for Mac or Windows installed, then you already have kubectl installed with it, thus you can skip that step too. Otherwise, follow the instructions on the site.
Finally, select the latest binary for Minikube for Mac or Windows and install it. For Mac, the latest binary is called minikube-darwin-amd64 and for Windows it is minikube-windows-amd64.
