Yes, NSWorkspace does not post DidTerminate notifications (and a few others)
for background and UIElement apps. This is one of those historical quirks that
must be maintained for bug compatibility.
The more modern -[NSWorkspace runningApplications] method gives you a list of
all applications, including background and UIElement. You can use KVO to
observe this property, and be notified when apps are launched or terminated.
Hope that helps!
