Screen Sharing on Your Mac with Mountain Lion

Screen Sharing on your Mac running OS X Mountain Lion lets you control another Mac on your network from your Mac. In essence, you see the other Mac’s screen on your Mac — and control it using your mouse and keyboard.

To set up Screen Sharing on the Mac you want to control remotely, follow these steps:

  1. Open the Sharing System Preferences pane by launching the System Preferences application (from the Applications folder, Apple, Launchpad, or Dock) and clicking the Sharing icon.

  2. Select the check box for Screen Sharing in the list of services on the left.

  3. Click either the All Users or Only These Users radio button.

    If you clicked Only These Users, click the + button and add the user or users you want to allow to control this Mac remotely. Notice that the Staff group is included by default.

To take control of your Mac from another Mac, follow these steps:

  1. Click the now-you-see-it-now-you-don’t Show tag to the right of Shared to open the Shared section in the Sidebar, if it’s not already open.

    All available servers appear.

  2. Click the name of the remote Mac you want to control.

  3. Click the Share Screen button.

    Depending on whether you clicked the All Users or Only These Users radio button, you may have to enter your name and password, and then click the Connect button.

    A window with the name of the remote Mac in its title bar appears. In it, you see the screen of the Mac you’re looking to control remotely.

  4. Go ahead and click something.

    Pull down a menu or open a folder. Isn’t that cool? You’re controlling a Mac across the room or in another room with your mouse and keyboard!
