Apple’s AirDrop is a convenient way to transfer files between Macs, iPhones and iPads. By default, it is usually located in the Favorites sidebar in Finder on macOS, but it can be easily removed by dragging it away. Fortunately, it̵7;s easy to add it to Favorites again if you accidentally placed it.
First click on the desktop to get the Finder in focus. Click “Finder” in the menu bar and then select “Settings” from the menu.
In “Finder Settings”, click the “Sidebar” tab.
In the “Show these items in the sidebar” section, select the checkbox next to “AirDrop.”
When you open a new “Finder” window, AirDrop should be reset to “Favorites” in the sidebar.
To move AirDrop and other items up or down the favorites list, drag and drop them where you want them.
