Introduction
If you reached this page because you saw an error message like the following printed by a Go program running on macOS 12 Monterey:
fatal error: runtime: bsdthread_register error
runtime stack:

then you are running a program built with an old version of Go (Go 1.10 or before). You will need to update your program or rebuild it with a newer version of Go.
Details
Programs built with Go 1.10 or before use a way of issuing system calls that is no longer supported by the kernel on macOS 12 Monterey. In Go 1.11 and later, system calls are issued via libSystem.dylib, which is supported by the OS.
What to do
If this is a program you downloaded or installed (for example, using Homebrew), you will need to download or install a newer version of it that is built with a newer version of Go.
If this is a program you built from source, you will need to rebuild it with a newer version of Go.
You might want to check your $PATH and manually clean up $GOPATH/bin and other old relevant Go binaries you've installed.
If you're trying to compile Go, go tool dist clean might help.
