I am having connection/tethering issues. Tried tethering my 5D Mark 3 to Lightroom 3. Did not work. Camera shows "Busy" message and the camera wont work. tried tethering my camera to EOS Utility 2.11.1 for remote shooting. Will not work. EOS Utility quits when my 5D Mark 3 is connected via USB. My Canon 5D Mark 3 firmware 1.1.3. I am on Mac OS 10.8.2.
Any help, any advise will be greatly appreciated. Thank You!
