With iChat (Snow Leopard/Lion) or Messages (Mountain Lion), you can share your screen with another buddy. Screen sharing allows both of you to work on the shared desktop and is helpful when you need to collaborate.
Note: Share your screen with those you trust; screen sharing gives your buddy one time access to your computer.
1. Log into iChat. If you need to set up an messaging account, click here.
2. Select a buddy in the buddy list.
3. To share your own screen, go to Buddies > Share My Screen.
To request to share your buddy's screen, go to Buddies > Ask To Share.
To end the screen sharing, press Control-escape, click the red icon in the upper left-hand side of the picture-in-picture window, or choose End Screen Sharing from the iChat status menu bar item.
