One method to help automate screen sharing with Mac OS X, was to create a vncloc alias for each system that you were connecting to. Â In 10.6 this has been mostly automated.
To find these shortcuts, navigate to your user’s Library -> Application Support folder, where you’ll find a folder named Screen Sharing. Inside that folder is a .vncloc file for every system that you have connected to.
To make things even easier, though, you can drag this folder to your Dock or Sidebar, where you’ll be able to get at it with a click mouse click.
