Hi, I want to know how does launchd start the user defined launchagents service when a "root" user logs in to the system. Iam using Mac 10.6 I have a launchdaemon and launchagent present in /System/Library/LaunchDaemons and /System/Library/LaunchAgents. When I login with a non-root user, my launchagent service is started as that logged in user. I can unload this service using "launchctl unload /System/Library/LaunchAgents/<plistfile>" If I login as root user,my launchagent service is started and working fine.But its not started as logged in user ie., root. If I try to unload through "launchctl unload /System/Library/LaunchAgents/<plistfile>" I get error: launchctl : Error unloading <id> This is because the service is not launched as root user. Above scenarios are working fine in Mac 10.5 as root and non-root user. When i see my launchagent service in Activity monitor, the parent process is the per-user launchd instance. The parent process of this launchd is system launchd with pid 1. I have tried to list the service using various commands: launchctl list launchctl bslist sudo launchctl list All these are not showing my launchagent service.Is there any special way, launchd launches launchagents service when a root user logs in Mac 10.6? How can i unload my launchagent service when the root user logs in?
