Answers to the questions we expect most — and a human at the end of the page.

My network stopped working

That's usually VPNKill doing its job: when it's armed and your VPN is not connected, all non-VPN traffic is blocked. Either connect your VPN, or click the VPNKill menu bar icon and choose Disarm (or Pause for a temporary window).

Setup

VPNKill needs two one-time macOS approvals during onboarding: allowing the system extension in System Settings → General → Login Items & Extensions, and allowing the content filter when macOS asks. The in-app onboarding shows exactly where to click.

Does it work with my VPN?

Yes — VPNKill is VPN-agnostic. WireGuard, OpenVPN, IKEv2, and corporate clients all work: it allows traffic on VPN tunnel interfaces and blocks everything that would leave through a physical interface. There is nothing to configure.

Uninstalling

Use the built-in uninstaller: open VPNKill's Settings → Uninstall VPNKill… and authenticate when macOS asks. It removes the filter extension, the filter configuration, and the login item in one step. For a fully scripted removal you can also run:

/Applications/VPNKill.app/Contents/MacOS/VPNKill --uninstall

We don't recommend just dragging the app to the Trash: macOS is supposed to remove the filter extension with it, but sometimes silently doesn't. If that already happened, see the next answer.

I deleted the app and my internet is blocked

The kill switch keeps enforcing even when the app isn't running — that's what makes it trustworthy — so a Trash-deleted copy can leave the filter active. To get back online right away: System Settings → Network → Filters → turn VPNKill off. (Toggling VPNKill off under System Settings → General → Login Items & Extensions → Network Extensions works too.)

To remove the leftover extension completely, reinstall VPNKill and use Settings → Uninstall VPNKill… as above.
