Hi there @jonashartmann,

Yes you will need kubectl installed locally on your Mac. Here is a link to the official documentation on how you can do that for Mac:

https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-macos

After that you can download your Kubernetes Cluster config from your DigitalOcean Control Panel directly rather than using the doctl command-line tool. You can see the exact steps as described here in the official DigitalOcean documentation:

https://www.digitalocean.com/docs/kubernetes/how-to/connect-to-cluster/#download

Once you have the config file downloaded, you can run the following command to interact with the Kubernetes Cluster:

kubectl --kubeconfig="use_your_kubeconfig.yaml" get nodes

Hope that this helps!
Let me know if you have any questions.
Regards,
Bobby
