Enabling encryption on AppleVNCServer
I'm tying to use VNC Viewer (RealVNC) iOS app, connecting to my own Mac running 10.6.8.
The connection works fine, and I can control my Mac, but reports the connection is unencrypted. This is the case over Wifi and 3G.
I have also tried to use both "Screen Sharing" and "Remote Management" from Preferences->Sharing.
How do I enable encryption?
MacBook Pro, Mac OS X (10.6.4)
