Apple Remote Desktop
Apple Remote Desktop is the inbuilt VNC client for the Apple Mac OS X operating system. Apple Remote Desktop (ARD) was first introduced in 2002, during the release of Mac OS X 10.2, and it is now in its third program version. ARD replaced Apple Network Assistant, an earlier variation of the program that is now wholly incompatible with Apple Mac OS X.
Apple Remote Desktop has, since its first version, featured the ability to lock the screen, restart the computer, perform simple file transfers, and put the computer to sleep. With each update, new features were added that made use of the Max OS X framework, such as remote tasks. With version 2 of Apple Remote Desktop, Apple introduced the cross-platform capabilities by opening support for the VNC protocol, along with the default Apple protocol ports.
Apple Remote Desktop can be installed remotely from server computers, which is useful when operating a large-scale network with new computers added all of the time.
ARD 3 introduced many new tasks including remote spotlight searches, using the dashboard, using Automator, using Power Copy, remote drag and drag, and much more. With ARD you can perform the tasks expected of all typical VNC software.
Along with the third-party VNC support for Windows, Apple Remote Desktop fully integrates with the Linux VNC client x11vnc.
