Hiding a Process (Making a Backgrounded App)
<dict>section (it doesn't seem to matter where):
In OS X 10.3 and later, add this instead:<key>NSBGOnly</key> <string>1</string>
Doing this will remove the process from the Dock, and from any menus that list active (visible) processes. To show it again, you can either put in a 0 instead of a 1 for the<key>LSUIElement</key> <string>1</string>
<key>, or you can remove the whole thing.
