Apple AirDrop is a convenient way to transfer files between Mac, iPhone andiPad. By default, it's usually found in the Favorites sidebar of Finder on macOS, but it can easily be removed by dragging it. Fortunately, it's easy to re-add it to Favorites if you've accidentally misplaced it.
First, click on the desktop to bring the Finder to focus. Click on "Finder " in the menu bar, then select "Preferences " from the menu.
In " Finder Preferences ", click l 'tab "Sidebar ".
In the section " Show these items in the sidebar ", check the box next to " AirDrop ".
Now when you open a new window " Finder ", AirDrop should be restored in the " Favorites "section of the sidebar.
To move AirDrop and other entries up or down in the Favorites list, just drag and drop them wherever you want.
