By default, the Dock sits at the bottom of the Mac display. The Dock was introduced in OS X and contains shortcuts to applications. As you move the cursor along the Dock, the icons will be magnified. You can relocate the Dock to the sides and you can set it to “autohide”. The size of the icons in the dock, and the amount of magnification when an icon is highlighted can also be adjusted.

To set the dock preferences:

  1. Click on the apple icon in the top Finder menu bar
  2. Click on “System Preferences”
  3. This will display the System Preferences dialog box
  4. Click on the Dock icon
  5. This will display the Dock System Preferences dialog box
  6. Use the sliders and checkboxes to set your preferences
