launchctl loads app with icon (OS X)
We are deploying an app to our students that is running as a daemon. It keeps them from using certain software. The problem is that when we initially deploy it we don't want to require a restart. So we decided to use launchctl to load the daemon manually. When we do it this way, though, the dock icon for the app is visible, even though the preferences for the app are set to hide the dock icon. When we restart the computer and let launchd open the process normally, there is no dock icon. Is there any way to mimic this normal startup behavior of hiding the dock icon?

Not my area of expertise, but can you make the icon a single pixel? Smilie

I guess we could do that, but it would still take up a full icon space in the dock and have a light under it.

I'm assuming that you are talking about an application bundle with a info.plist in the application bundle. You could do this
Code:
defaults write /Applications/YOUR_APPLICATION.app/Contents/Info LSUIElement 1

The operating system has a built in managed client framework which may be a better solution.

If you restart it frequently from cron, that takes care of boot, too.
