tar xvf openshift-client-mac-arm64.tar
sudo mv oc /usr/local/bin

Remove oc from Apple Quarantine and login to OpenShift via CLI.

xattr -dr com.apple.quarantine oc 
apiServer=$(az aro show -g $RESOURCEGROUP -n $CLUSTER --query apiserverProfile.url -o tsv)
oc login $apiServer -u kubeadmin -p <kubeadmin password>
