I have a MAC, the new Lightroom 5 and the Canon 5D Mark lll. Instructions for tethering seemed straightforward but I can't seem to get it to work. I'm all plugged in with the USB cord ( also plugins enabled) and lightroom sees the camera but I can't shoot. It says busy in the camera and the shutter won't depress. I have tried waiting but how long should I have to wait?
would be grateful for any ideas. I am new to lightroom and to tethering so don't have a lot of ideas myself for solving the problem.
thanks
