My wireguard install has broken and I'm unable to fix it Since I've installed Wireguard on my MacBook Air running MacOS Sierra it hasn't given me any major problems until now. I've been using wgcf to generate the wireguard config file, but I don't think that has been the cause of my issues with wireguard. So, in the last day or two when I run wg-quick up ~/wgcf/wireguard-profile.conf it prints three lines and then hangs.
[#] wireguard-go utun
[+] Interface for wgcf-profile is utun1
[#] wg setconf utun1 /dev/fd/63

I've been trying to fix this in all different kinds of ways from using brew to uninstall and reinstall wireguard-tools and wireguard-go. I manually downloaded the latest version of go and wireguard-go and it still hangs like it did before. At this point I don't know what to do.
According to gdayhowyagoin on reddit , wireguard-go version 0.0.20210212 is the culprit. If you're using brew, you can see how they downgraded it, but if youre using macports, you can follow this:
git clone --single-branch https://github.com/macports/macports-ports.git
cd macports-ports
git checkout e01555c11df59855b73fd540accc778a41145bf8
cd net/wireguard-go
sudo port install

I hope this clears your issue.
