I was using Chicken of the VNC for a long time without knowing that OSX does have its own VNC client. I do not know if this comes with Mountain Lion or not.
However, this little app is like Grapher; you don’t really see unless you find for it. It’s calledScreen Sharing. It’s in:
The easiest way for me to get there is opening up Terminal, type open
/System/Library/CoreServices You will see many files. Look for Screen Sharing. There you go.
It’s the easiest, quickest VNC client so far. Surely, you can capture screen, scroll with guesture and almost everything you can imagine. Oh and it’s built-in. I can take control over my Ubuntu one very very easy as shown below.
