Screen Sharing allows you to connect to another Mac within the same network, share its screen to observe or control it. Here are two new features I noticed in OS X Lion worth mentioning.
- Go full screen. You can now share a screen and go full screen all the way; controlling it as though you are running your own mac.
- Observation mode. Observation mode allows you to monitor a remotely connected Mac without interfering user on the other side. Mouse and trackpad movements will be disabled in observation mode. You can switch between Controlling or Observing mode by using the shortcut Option + Command + X.
