Protocol was created to allow a user to access a computer from a different location. It uses a protocol called RFB which is a cross-platform remote control protocol. It was created to help computers communicate from a distance without needing a dedicated line. It has an intuitive interface that is easy to use, you can seamlessly control the remote computer with your keyboard and mouse. TightVNC is a remote desktop application, which can be used to view and interact with a computer over a network connection. The interface is fast and responsive and it is easy to use. RealVNC client version used is '5.0.5 Windows 64bit' on Windows 7 Professional.Ībout the 'no keyboard connected' error, I've not tried nothing but connecting a keyboard to the MacMini (when I'm remotely connected I need to have a real keyboard connected to the Mac Mini !).TightVNC is a free and open-source application that allows you to remotely view and control a desktop over the Internet. For example there is no distinction between left and right buttons when you are connected with VNC (for every client I've tested). In my tests the real events that are received by the server are always different from the local events of an attached keyboard. Use RealVNC or TightVNC (2.7.10 or above see ) clients to have 'Option' key enabled: TightVNC prior to 2.7.10 and UltraVNC viewers do not send the 'Windows' key (which will be mapped to 'Option' mac key).For strange reasons, with TightVNC both the native OSX server and the RealVNC server treats both the Win/Alt keys as Command. Use VineVNC server, because I found this is the only VNC server that generates complete Mac keyboard events.

Leave native language keyboard on the remote Mac, but set 'US Keyboard' on the local PC.

I've tried with the native VNC server installed in OS X 10.8.4 Mountain Lion, the one installed in OS X 10.6.8, with VineVNC server (v4.01) and RealVNC server (v5.0.6). I suggest to use it to find what is happening for keyboard related problems.

I've performed some tests with Event Viewer tool found into KeyRemap4MacBook software, by comparing events with the local keyboard and the VNC connected keyboard. I found nearly the same problems with Mac-Mini (late 2012), with Italian keyboard.
