Mac screen sharing also allows you to remotely view and take control of another Mac's screen. This can be very handy for getting or giving help with troubleshooting a problem, getting answers to questions about how to use an application, or simply accessing something on your Mac from another computer. Macs come with built-in screen sharing capabilities, which can be accessed from the Sharing preference pane. The Mac's screen sharing capability is based on the VNC (Virtual Network Computing) protocol, which means not only can you use another Mac to view your screen, you can use any computer that has a VNC client installed. Setting Up Screen Sharing on your Mac The Mac offers two methods of setting up screen sharing; one appropriately called Screen Sharing, and the other called Remote Management. The two actually use the same VNC system to allow screen sharing. The difference is that the Remote Management method also includes support for Apple's Remote Desktop application, a for-fee application used in many commercial environments to allow remote staff to troubleshoot and configure Macs. In this article, we'll assume that you're going to use the basic Screen Sharing, which is more applicable for most home and small business users.

You can select 'All users' or 'Only these users.' In this case, 'users' refers to Mac users on your local network. Make your selection.If you chose 'Only these users,' use the plus (+) button to add the appropriate users to the list.When you're finished, you can close the Sharing preference pane. Once you have screen sharing enabled, other computers on your local network will be able to access your Mac's desktop. To access a Mac's shared screen, you can use the Finder or iChat.
