Topic: Darwin: launchctl logs for a service

How do we get the logs for a failing launchd service? This is the github-runner service setup by nix-darwin.

It is surprisingly impossible to find a way to do this. One of the reasons macOS sucks compared to Linux.

$ sudo launchctl kickstart -kp system/org.nixos.github-runner-heist-extra-1
service spawned with pid: 84781
$

And that PID no longer exists after that.

Guess that's why it is failing -- my token expired.

(But can't confirm -- just guessing)

You will have to use either the log cli command in MacOS, or if you have access to GUI you can use Console app to start filtering all the messages with system/org.nixos.github-runner-heist-extra-1 in it and then kickstart your daemon

If you still don’t see anything, you can try enabling debug mode first, with launchctl debug and then start filtering for logs again

Console app never showed any logs for the crashed service, but I'll try the debug command next time this happens.

Nothing's coming through:

❯ sudo launchctl debug  system/org.nixos.github-runner-dioxus-desktop-template-1 --stdout ~/out --stderr ~/err
Service configured for next launch.

And:

srid on appreciate ~/code
❯  sudo launchctl kickstart system/org.nixos.github-runner-dioxus-desktop-template-1

srid on appreciate ~/code
❯ more ~/out

srid on appreciate ~/code
❯ more ~/err

The new nix-darwin module writes the log files (see topic referenced above), thus allowing me to not repy on Apple's slipshod tech.
