I am trying to run my audio daemon application as root at system startup via launchd. It's not going well! First, when I try to run the program as any user but root (using the UserName plist property in launchd) I get the following error (fatal) via the console:

Are you mistakenly linked to Cocoa or AppKit.framework? It's not supported by launchd daemons. You'll need to manage your own main thread loop yourself, or use CFRunLoop/NSRunLoop. NSApplication is part of AppKit, and connects to the window server for event and window management, etc. -- Shaun Wexler MacFOH http://www.macfoh.com
