wireguard on mac

Read this somewhere earlier about using wireguard-go and cli to activate/deactivate wireguard working perfectly on Ventura while the Appstore wireguard app was not working properly.

  1. Install wireguard-go and wireguard-tools with brew in terminal:

brew install wireguard-go wireguard-tools

  1. Create the wireguard config directory and move your config file (exported from the Appstore wireguard app) to that directory:

sudo mkdir /usr/local/etc/wireguard

sudo mv your-config.conf /usr/local/etc/wireguard/wg0.conf

  1. Activate wireguard with your config:

sudo wg-quick up wg0

  1. Check your IP on whatsmyip.com see if its the IP of the wireguard VPN server.

  2. To disconnect from wireguard do:

sudo wg-quick down wg0
