The Quick Look Share Menu in OS X El Capitan

By Bob LeVitus

If you use an Apple iDevice with OS X El Capitan, you’re surely familiar with the rectangular button with an arrow escaping from it, as shown here.

Here’s the Share menu, and it has as many as seven options (depending upon the type of file you selected):

The Share button and Share menu are displayed here with the Quick Look window (left).

The Share button and Share menu are displayed here with the Quick Look window (left).
  • E-mail: Launches the Mail app and attaches the selected file to a blank message, ready for you to address and send.

  • Message: Launches the Messages app and puts the selected file in an outgoing message, ready for you to address and send.

  • AirDrop: Sends the selected file to other Mac users or iDevice users. As long as you’re on the same Wi-Fi network, your file transfer takes but a single click (or a single tap on iDevices).

    Note that the next three options appear only when you select an image file. If you don’t see them when you click your Share button, you probably selected a PDF or other type of file that can’t be uploaded to Twitter, Facebook, or Flickr.

  • Twitter: Tweets the selected file to your Twitter account.

  • Facebook: Posts the selected file to your Facebook account.

  • Flickr: Posts the selected file to Flickr, a popular photo-sharing site.

  • More: El Capitan’s extensible architecture lets you add other services (such as Vimeo or LinkedIn) and apps (such as iPhoto and Aperture) to your Share menu. To manage these extensions, choose More from the Share menu. Alternatively, you can launch the System Preferences application, click the Extensions icon, and then click the Share Menu item on the left side of window.
