OS X Mountain Lion: 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.
- Open Sharing preferences if it isn’t already open, and then select the Screen Sharing checkbox.
- 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.
- 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.
- (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.
