To put it short, OS X Lion takes good care of you when sharing your screen between two networked Macs. The new app includes changes such as a brand new tool bar, and perhaps most critically, new per-user screen sharing functionality. For instance, as you can see in the top image, my computer’s address is “vnc://10.0.1.2.” Simply entering that address in Safari will launch Screen Sharing in OS X. You can also access screen sharing by entering your computer’s address in Safari. Once screen sharing is enabled, it can be launched by opening Finder, selecting the Mac you’d like to access in the source list to the left, and then clicking the “Share Screen…” button. To launch Screen Sharing, first enable screen sharing by opening Settings.app, selecting the Sharing pane, and ensuring that screen sharing is selected.
While screen sharing on a Mac is certainly nothing new, having been around since Leopard, Apple has added some neat new features to the Screen Sharing app in OS X Lion.
