Mac OS X 10.5 Help
About screen sharing
With Mac OS X Leopard (v10.5) you can connect to another computer on your network and display that computer’s screen on your computer. You can access the other computer as if it was the computer you were using. While you share the computer’s screen, you control everything that happens on that computer, such as opening documents or applications; opening, moving, or closing windows; and even shutting off the computer.
You can also set up this computer to share your screen with another computer on your network.
Screen sharing can be useful if you need to access a computer at home while you are away from home. It can also be useful if you’re trying to solve a problem on someone else’s computer, or you want to collaborate with someone on a project, such as building a website or creating a presentation.
Mac OS X screen sharing is compatible with Virtual Network Computing (VNC), an industry standard for remote controlling computers on a network using TCP/IP. It is also compatible with Apple Remote Desktop (ARD) v2.1 or later.
If you have a paid .Mac account, and are using Mac OS X Leopard (10.5), Back To My Mac allows you to connect to any computer that has your .Mac user name and password entered in the .Mac pane of System Preferences, even if that computer is on a remote network.
