Currently, there is no way to disable the extra dock and menu bar added in Parallels coherence when using a macOS guest. Instead, it should be removed (but re-added with a toggle), and merge the macOS guest's dock and menubar items and context menus into the host macOS session. To verify, Coherence should support macOS 14 up to macOS Leopard or Snow Leopard, and macOS Tiger or earlier for PPC as well in the future, for classic macOS applications to be used like a normal macOS app, even the first ones.
