NSWindow makeKeyAndOrderFront makes window appear, but not Key or Front

Question

makeKeyAndOrderFront is not making my NSWindow key or front.

My app does not have a main window or menubar, which may be part of the proble

Answer 1

Stab in the dark: You have LSBackgroundOnly set in your Info.plist. That's what makes this not work: A background-only application cannot come to the foreground, which is why your window does not come to the foreground.

If you want your app to not show up in the Dock, set LSUIElement instead. This suppresses your app's Dock tile and keeps it from showing its own main menu in the menu bar, but preserves its ability to bring a window frontmost and make it key.
