I am a beginner to Kubernetes and starting off with this tutorial. I installed VM and expected to be able to start a cluster by using the command:
minikube star
Figured out the issue. VirtualBox was not installed correctly as Mac had blocked it. It wasn't obvious at first.
Restarting won't work if VirtualBox isn't installed correctly.
System Preferences -> Security & Privacy -> Allow -> Then allow the software corporation (in this case Oracle)
Restart
Now it worked as expected.
