This is a pretty well hidden feature of OSX: It's a VNC client shipped with the OS but not accessible from Spotlight or any shortcuts (AFAIK). To open it, you can either:
- Open Safari and enter "
vnc://192.168.0.10" in the address field (replace the IP-address)
- Open the app directly (from Finder or Terminal) from it's location at
- From Finder, press cmd+K (Connect to Server) and enter the vnc-address.
When you have the app open, you can pin it to the Dock as with any app.
Thanks to DavidTheExpert for this great tip :)
