The macOS Dock is a strip of icons that appears by default at the bottom of your screen at all times.
The Finder is the first thing that you see when your Mac finishes starting up. It opens automatically and stays open as you use other apps. It includes the Menu Bar at the top of the screen and the desktop below that. It uses windows and icons to show you the contents of your Mac, and other storage devices.
A contextual menu provides convenient access to frequently used commands associated with an item. From the user’s perspective, a contextual menu is a shortcut to a small set of commands that make sense in the context of the current task. If you have a two-buttoned mouse or trackpad, the contextual menu appears when using the right-mouse button. It is also possible to open contextual menus on macOS by holding down the ^ (CTRL) key and clicking with the left-mouse button.
The macOS title bar is the area at the top of every window in macOS. Flume's title bar is dynamic, and adjusts based on the current content that you are viewing. Common actions related to the view are available in this area.
