JollysFastVNC is a secure ARD and VNC client. Its aim is to be the best and most secure VNC client on the Mac. JollysFastVNC is shareware. This means you can try out the program for free. You should consider buying it if you use it. You will be able to use it without buying it, but I strongly suggest you buy it and support development of new versions. It’s free to be used for connections to ScreenRecycler.
