1. On Mac (machine to be controlled)
   1. Open System Preferences (it's in the Apple menu)
   2. Open the Sharing panel
   3. Check the box Apple Remote Desktop

      4. IMPORTANT: Set Color depth to High color (15 bit) or better, otherwise connection will fail

The instructions above are for a Linux machine with Remmina installed, but you can do the same from a tightVNC command line (cli or GUI, Windows or Unix). You can also access using other tools like krdc.

Microsoft Windows has various third party VNC programs available. I have found tightVNC to be the best for my purposes. Also, check out the paid product UltraVNC.

2. On Windows Machine
   1. Install tightVNC (https://tightvnc.com/)
   2. Create connection

1. Start and run a VNC server on the Linux machine. Be sure to set a password

   1. vnc:server_ip:5900 - Alternately, install Chicken of the VNC. Development stalled in 2005, but the project was restarted in 2010 with the name changed to simply Chicken, which can be downloaded from https://github.com/boecko/chicken/. I have not use this product. - You can also use Remote Ripple for Mac, a paid version of TightVNC created for OS X.
