The Mac Dock comes pre-loaded with some of your system's most-used applications. You can also customize which applications are included in the Dock. 

Sometimes that Dock can disappear, making navigating your Mac more tedious. The upgrade to Mac's Catalina OS, for example, has seen users complain that their settings are automatically changed, so the Dock disappears by default. 

If you're in full screen mode, it's important to note the Dock will not show up. To do so, disable fullscreen mode by hitting the "Esc" key and hitting the green button in the top left corner. 

You can also check whether your Dock is set to hide automatically by moving your cursor over the bottom edge of your screen and seeing if it reappears. 

If neither of these things is the reason, sometimes adjusting your settings can often make your Dock reappear. Here's how to get your Dock back.
