What is the recommended way to run a GUI app before loginwindow post Tiger? In Panther I could set dependencies in StartupItems In Tiger I called my script from rc.local so it would run before loginwindow. I see that rc.local is still supposed to work post Tiger, but it does not seem to be able to force it to run before loginwindow and seems to be lumped in with StartupItems. Also, perhaps a separate issue is that I get a message that untrusted apps can not attach to or launch WindowServer on demand before loginwindow. Is this somehow related to LimitLoadToSessionType? I am a scripter/sysadmin attempting to run iHook to display progress of a script before a user can login. I do plan on doing more on demand, but some tasks like installing software that requires a reboot don't make sense post-login since the user would be interrupted and told to reboot soon after they logged in anyway.
