I've been using Luna for about 2 years now, to enable my iMac to work as secondary display for Macbook(s). Connecting over thunderbolt makes the network connection smooth and also charges the macbook. Only feature wish to have, is ability to use secondary (iMac) mouse also on primary mac. I think there was some limitation that didn't allow this? Now I'm just using blutooth keyboard and mouse connected to macbook.
