OS X Mountain Lion: Share your screen

Share your screen

You can let others view your screen and control your computer. While your screen is shared with another computer, a user of the other computer sees what’s on your screen and can open, move, and close files and windows, open applications, and even restart the computer.

  1. Open Sharing preferences if it isn’t already open, and then select the Screen Sharing checkbox.
  2. To specify who can share your screen, select one of the following:
    Option Description
    All users: Anyone with a user account on your computer can share your screen.
    Only these users: Screen sharing is restricted to specific users.
  3. If you selected “Only these users,” click Add (+) at the bottom of the Users list, and do one of the following:

    • Select a user from Users & Groups, which includes all the users of your Mac.

    • Select a user from Network Users or Network Groups, which includes everyone on your network.

    • Select a person from your contacts. Create a password for the person, and then click Create Account.

    • Click New Person. Enter a name and password for the person, click Create Account, and then select the person from Users & Groups.

  4. (Optional) To specify who can control your screen, click Computer Settings and select one or both of the following:
    Option Description
    Anyone may request permission to control screen: Anyone on your network can request to share your screen.
    VNC viewers may control screen with password: If you use a VNC viewer, create a password that the VNC viewer can enter to control your screen.

    If you share this computer’s screen using only the built-in screen sharing viewer in OS X, don’t create a password.
