What is Apple Screen Sharing?
Screen Sharing is a VNC client by Apple Inc. included as part of Mac OS X v10.5. It allows remote observance or control of any Macintosh machine on the local network that has Screen Sharing activated. It may also be used over the Internet via iChat. Because Screen Sharing is a VNC client, it may also be used to control any computer running a VNC server if the IP address of the target computer is known and accessible.
You can now use an Apple ID to authenticate with another Mac running OS X to start a screen-sharing session. This is perfect for giving others access to your Mac without creating separate user accounts. Simply add their Apple IDs to the list of authorized users, and they can log in with their credentials.
The new Observe-Only mode lets you watch a remote computer without controlling the mouse or trackpad movements.
Screen Sharing includes a toolbar that provides access to useful tools and settings such as screen resolution, Clipboard access, and screen capture.
