Dup of #4255. You're actually using Go 1.18.0 so you're hitting https://github.com/golang/go/issues/51759

Use Go 1.17.x or Go 1.18.1 when it comes out shortly.

Or if you need to build from our HEAD on macOS, use https://github.com/tailscale/go which contains the fix. Release binaries: https://github.com/tailscale/go/releases

Thank you! I did a quick search for tsnet and didn't see that issue. Will be build from source.

bradfitz commented 2 years ago

We've worked around this server-side. You can use Go 1.18.0 on macOS now.

Nice!
