On smaller screens, where pixels are more valuable, the additional space the Dock takes could be problematic. Luckily macOS allows you to hide the Dock to regain space while keeping it accessible when needed.  Once you tweak the following settings, the Dock disappears when not in use. You can bring it up just by hovering your mouse over the bottom part of your screen – assuming the Dock is in its default location. Or, you could always just use a keyboard shortcut (Command + Option + D) to hide and unhide it without the mouse.

  1. Click the Apple icon to open the menu.
  2. In the menu, select System Preferences.
  3. Select Dock & Menu Bar from the next window.
  4. In the window that opens, select the Automatically hide and select the Dock option.
