In one application I have to display a splash screen while a poorly written framework (DAQmxBase from National Instruments) takes 6 to 11 seconds to initialize itself on the main thread.
To do so, I display my splash screen as a non modal, top-level, centered window (use NSWindow's setLevel:NSFloatingWindowLevel to make it top-level).
Do you require your splash screen or the registration window to be modal?

Other modal dialogs *could* appear and go away before the splash screen appears, so order is important. If a modal dlog *does* appear beforehand (e.g. registration), then the splash screen will display. If not, something is preventing the splash screen from showing. This got me thinking it was event manager related, so I added this after showing the splash screen:
