Sorry for later reply.
We'd like to know your $GOOS environment variable.

@yseto I am using the default environment and the device is a Mac M1

@Ran-Xing
On M1 Mac macOS, I seem to be able to get the value.

Please let us know what results you get if you do the following

go env

git clone https://github.com/mackerelio/go-osstat
cd go-osstat/
go run ./cmd/osstat
