I don't understand you, please explain how you tested the sample?

I tested the same commit and i think all works proper:

Remarks:

• ./sample -s ... command prints a message only if an error happens, it produces no output in a different case;
• tail -f log command pipes the daemon's log to the console in my tests.

My os version "Darwin Kernel Version 16.5.0"

run ./sample on Darwin after go build, Nothing generated, No PID file NO log file. output is '[1] 57268 killed'

[sevlyar]

It looks really strange. @vus520 could you give me output of go version && go env command? Thank you.

I updated my OSX Kernel Version up to 16.6.0 and can not reproduce this behavior.

[timfallmk]

@sevlyar I get this as well.

A pid and log file are written, but the pid file is blank.

[timfallmk]

Nevermind, I figured it out.

[ademenev]

Nevermind, I figured it out.

How did you solve the issue?

[timfallmk]

@ademenev its been a long time since I commented so I don’t remember the problem or context, but I switched to using a fork that fixes macOS issues https://github.com/timfallmk/go-daemon
