Make a borderless window (google NSBorderlessWindowMask) and add an NSImageView to it, then show at startup.

then show at startup.

Would you do this through a custom awakeFromNib? or is there a better strategy?

Usually it's at awakeFromNib or applicationDidFinishLaunching. awakeFromNib should probably be reserved for setting up UI stuff specific to that nib, while applicationDidFinishLaunching is better for general launch tasks. But it's still up to how the app was written.

If your app is quitting without you quitting it yourself, then it's probably crashing.
