Minikube doesn't work on Mac with hyperkit driver and VPN
This is a known issue. You can try using --vmdriver=virtualbox or --vmdriver=vmwarefusion. Note that you will either have to install VirtualBox or VMware Fusion (Paid license required)
I'm on Mac and I faced the same issue. I solved it by applying the flag --hyperkit-vpnkit-sock=auto to minikube start --vm=true. This will, according to the docs:
Location of the VPNKit socket used for networking. If empty, disables Hyperkit VPNKitSock, if 'auto' uses Docker for Mac VPNKit connection, otherwise uses the specified VSock (hyperkit driver only)
