WireGuard is an excellent, secure and fast VPN with full support for macOS. It is frustrating however that the official macOS app is only made available via the Mac App Store, necessitating an Apple ID to sign in with.
Whilst the source for WireGuard is available on GitHub, there is no downloadable app there.
Fortunately some other enterprising person has taken it, built it and put it up on GitHub: Wireguard macOS App.
I’ve checked it out and it seems legit, none of the security vendors and no sandboxes on VirusTotal flagged this app as malicious.
