Hi,
I have a launch daemon in /Library/LaunchDaemons and want to let users manually start and stop the service from my application's user interface, which involves them authenticating of course.
I am therefore running launchctl with an effective uid of 0 but their own real user id. I believe launchctl uses the EUID to decide which launchd to talk to, and so it's talking to the wrong (per user, not system) launchd.
Is there any way to get launchd to use the EUID instead of RUID and force it to talk to the system-wide root launchd instead?
Can't you just setuid() before calling launchctl? This way RUID == EUID == 0. -- Per Olofsson, IT-service, University of Gothenburg
