I am a professional photographer who relies heavily on LR for my digital workflow. I tether my Nikon D3 and D3x to LR frequently. I've never had an issue with tethering my cameras to LR until this past week. And, after much frustration and processes-of-elimination and testing the issue across multiple machines, I BELIEVE that the problem has to do with the latest OSX 10.6.8 update when running LR 3.4.1.
You can read my initial post about this problem on Adobe forums here http://forums.adobe.com/message/37883... when I was stumped about why it was happening.
Then you can see my follow-up post about this problem today here http://forums.adobe.com/message/37894... and why I think it has to do with the recent 10.6.8 update.
Please feel free to contact me for anymore information. I really hope you can look into this issue.
Thank you,
Scott Woodward
