Look at Safari, iTunes, Finder, Graphing Calculator (OS 9), and GIMP (X11).
Each has it's own set of widgets, it's own window scheme, it's own menu bar system (well, Aqua and Metal use the same menu bar), and generally there's no interface consistency on the mac desktop.
I know there are various programs that can make all of these different interfaces a little more consistent (Liquid for Classic, Metallifizer for Metal, GTK-AquaX for X11, etc.), but Apple really needs to work on getting all of their different interfaces on the same page
