Hello, I've been searching around and have not been able to find any hints. I have a plist, pref pane based app that fires off at a preset time. With Tiger its all good. However Leopard is failing to run the app at the scheduled time. Pasted are some errors that I hope will help to identify the problem. I'm not the developer, who is a contractor dealing with another deadline. I'm hoping to gather information on his behalf in order to expedite the resolution. I have access to the dev boxes and can run commands and capture any needed output. Any help appreciated, and thanks in advance, Eddy vmini01:~ $ cat /tmp/agentLauncher.stderr 2008-01-17 12:38:00.136 AgentLauncher[218:20b] Cannot checkin with launchd, exiting. 2008-01-17 14:14:00.032 AgentLauncher[323:20b] Cannot checkin with launchd, exiting. 2008-01-17 14:36:00.057 AgentLauncher[389:20b] Cannot checkin with launchd, exiting. vmini01:~ $ vmini01:~$ tail -f /var/log/system.log | grep devapp Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key for array: excluded Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key for boolean: Enabled Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key for array: included Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key: ServiceDescription Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key: server Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key for string: cistern Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key: bucket Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key for integer: finish Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key for string: CustomerID Jan 18 10:54:44 vmini01 com.apple.launchd[1] (com.devapp.AgentLauncher): Unknown key: CustomerID vmini01:~ eddy$ sudo launchctl list | grep devapp - 1 com.devapp.AgentLauncher vmini01:~ $ ls -la /Library/LaunchDaemons/ total 8 drwxr-xr-x 3 root wheel 102 Jan 18 10:54 . drwxrwxr-t+ 46 root admin 1564 Sep 14 10:14 .. -rw-r--r-- 1 root wheel 1248 Jan 18 10:54 com.devapp.AgentLauncher.plist vmini01:~ $ -- Eddy Martinez fasteddy760@gmail.com
