How to Log into a Mac via TightVNC

The “screen sharing” feature built into Mac OS X uses the virtual network computing protocol. You can use TightVNC or any other VNC client application to log into a Mac remotely and control its desktop. Before you can log in with VNC, both screen sharing and a VNC password must be enabled on the Mac. If the Mac and the computer running TightVNC aren’t on the same local network, you’ll also have to configure port forwarding.

    Click the Apple logo at the top left corner of the Mac’s screen and select System Preferences.
