Where can I find free VPN for my Mac?

I'm looking for a free Vpn for my Mac (that works for Netflix too).

Can someone help me there? (for 2 hours and not for a month or so)

NOWHERE, because nothing in the world is really "free" - not even a VPN.

Good servers cost four-digit amounts a month, of which every good one has quite a few.

Otherwise, why are you not ready to pay a low single-digit amount? You have an iMac.
