Can I send a growl message to another user on the same computer in OSX?

Question

Currently, my application uses a growl to send a random message to a user, which works great when I develop it. But as soon as it starts as a production one, as a system-level launch daemon under another user, growl messages no longer appear.

So the question is: Can I send a growl message to another user on the same computer in OSX?

Answer 1

Perhaps you can send a message over the network ( http://growl.info/documentation/developer/protocol.php ) to localhost / 127.0.0.1. But I can’t find a hint in the docs for targeting a special user.
