While the wireguard protocol does live up to its grand promises of being lightweight and fast, the abysmal lack of official documentation and especially troubleshooting suggestions makes it nearly impossible to fix your setup if it doesn't work on the first try. Unless you're skilled at networking or you have assistance from someone with a working installation, it's next to impossible to troubleshoot a nonfunctional installation. That said, it fulfills all promises made about the protocol if you do manage to get it working.

This works more or less flawlessly. The protocol itself is incredibly fast and efficient, and this implementation maintains that.It is completely integrated with macOS's networking frameworks, so it can be managed in System Preferences like a normal VPN and run without keeping a separate application open. It seems to have almost no system overhead, either, and it is very easy to set up. It also properly stores credentials in Keychain Access, rather than trying to manage them itself.There is one oddity, though: the configuration dialog consists of one text box that contains the config file, rather than a series of form fields like the iOS client. I don't think it is worse, necessarily, but it'd make more sense if the UI was consistent across both platforms.

This Application serves as an excellent reference WireGuard client. Whether you are connecting to a service like NordVPN, or have a WireGuard server set up to access local network resources from just about anywhere, this Application will get the job done in the vast majority of cases. Additionally, I appreciate the fact that wire guard tunnels show up in system settings along side other VPN connections (something which most OpenVPN clients do not support).

This is a fantastic bit of software. The initial setup can be someone of a bear and confusing but once you get the keys set up and single port forwarded its off to the races. Its amazingly fast compared to openvpn and more secure. Some might be scared off by opening a port but dont be. If you run a port scan you cant even see the port is open. It only reports open when wireguard handshake is complete. Pair it will a VPN provider and you have a fast and reliablie vpn setup. Highly recommend.
