Lightroom: Tethering Bug: OSX 10.6.8 + LR 3.4.1 [Nikon]

Im wondering if Adobe has a developer copy of OSX Lion to play with. I just bought this new MBP a month ago and have been given a free upgrade to Lion when it comes out so I was planning on using it.
As it turns out... this laptop came with 10.6.8 installed, so I dont even think its possible for me to revert to a pervious version of the OS.

Side note/thought: I know Windows has some kind of usb power management that puts them in a type of "sleep mode" when the OS is trying to conserve power. I wonder if OSX is doing a similar thing, not realizing that the camera is still tethered.

Its nice to have this forum to connect with Adobe employees... Its nice to know there is someone listening to the end users out there. :)

Thanks!

Ahh.... Question: Is there a keyboard shortcut to take a photo in tethered mode?
Im so used to using " Command K " in Capture One that i kinda miss it.

Here's a tech doc on reverting back to a previous version of OS X 10.6:

Reverting to a previous Mac OS X version

Having the same problems . D700 into LR 3.41 onto my MBP 10.6.8
I lose my tethered connection randomly - sometimes it seems that it happens when I take a break !
I thought that the cables were faulty and cleaned all the plugs , changed cables but the problem continues. I started using my Nikon Camera Control 2 but this also crashes from time to time so maybe it's not LR but the OS.
Thanks.

I've done quite a bit of testing and am unable to reproduce this issue using any supported Canon camera. There may well be a problem with Canons, but if there is, it's a different problem. If you are having a problem with Canon cameras and tether in Lightroom, please start another thread, and provide as much detail as possible.

Thanks,

Hi

I am a professional photographer shooting Canon 1dsmk3 and 5dmk2. Both cameras shooting tethered to LR 3.4.1 and OS 10.6.8. I have been having the exact same issues. LR acknowledges the camera when it is tethered. If I fire a few frames everything is fine. If I pause and start shooting again the files won't download. LR still shows the camera attached and then LR will crash with spinning ball showing. The only thing I can do is then restart my MacBook Pro. I shoot with a card in the camera as my back up workflow. I have tried different CF cards, USB leads and different USB ports on my mac and nothing makes any difference.

My work around at the moment is to shoot tethered to the Canon software (Camera Window and Eos Utility). Then set up LR to auto import from a watch folder. This works fine. I thought that upgrading to Lion would help. However as far as I understand the Canon software will not work on Lion so my fall back work around will not work!

Really need this to be sorted out or if Adobe can try Lion and let us know if this helps. I rely on LR for all my work and its a real set back to have to deal with these issues.

Thanks,
Ben.

I shoot professionally as well and this is a real problem. I started another thread yesterday about it because this one seems to have been "solved", although hardly for me. I shoot the Canon 5d1 + 5dII and lightroom disconnects from the USB ports if you take any sort of break at all. It's absurd it's been this long with a solution besides downgrading to an outdated version of OSX, which quite frankly, makes no sense since windows users are having the same problem. Like above I always shoot to a card as well. I was going to use the Canon utility and have lightroom watch that folder but yesterday I downloaded Capture One Pro and I have to say this lightroom tether disconnect may be a blessing in disguise. Right now I'm using capture one (flawless) to tether and process the raw files and cataloging in lightroom, but this is only because I haven't had time to look at the capture one cataloging structure. Capture One Pro (i think you have to use the pro edition for tether) has a 30 day free trial so if you're having problems I would give it a try. I figured if lightroom can't get their product working within the 30 days I'll bite the bullet and pay for capture one, but I'm so impressed with capture one that I think at this point I'm a "former" lightroom user that's only still using it so I can access my old catalogs. When a professional level problem goes on this long without any action from the provider you have to ask yourself if this is a solution you want your photography business to rely on. For me the answer is no.

I too have had this same problem since updating both LR 3.4.1 and OS 10.6.8. I shoot with a D3x. I certainly hope there will be a fix for this. I am using a workaround now, but would like to shoot tethered through LR

Thought I'd follow up with my progress with this.
I was advised to delete the adobe lr plist in library.
Completely solved the issue and lr is also now much faster and responsive.

I concur with ben ... deleting the preference file and re-starting Lr did the trick ... tested a D200 and D300 connected to a Macbook Pro running Lion and Lr 3.4.1 for several hours ... no issues whatsoever ....

Do you mean Library > Preferences > com.adobe.Lightroom3?

If the fix stated above came from Adobe... could we get an official confirmation on it? I dont mind deleting files... I would just like to feel comfortable doing it. :)

Also... I would love to see some clear direction on exactly what file to delete and exactly how to get there. When I go to the Finder, I see two Library structures. One under Mac HD and one under Users. I dont know if it makes a difference or if they are the same Library folder.

I agree with Jeff on this. I am a little reluctant to delete anything. It would be nice to hear from an Adobe employee directly on this specific fix suggestion and/or any update on the progress of implementing a solution to this problem from their side. I have also held-off on upgrading to Lion for fear of compounding problems with LR3 even further. Frustrating all around.

To find the preference file for your computer look here: http://kb2.adobe.com/cps/843/cpsid_84...

With Lightroom CLOSED remove any "com.adobe.Lightroom3.plist" and Lightroom 2 plist files to your desktop and restart Lightroom which will generate new preferences.
If your problem is not solved you can simply replace the new preferences with the old.

Ok... a few questions...
What settings or preferences are actually stored in this .plist?
Will I need to reset anything?

The info from Geoff and Lee Jay is correct. You won't hurt anything by removing your preference files. You don't have to throw it away, you could just move it to the desktop, for example. Then, if nothing was fixed, you could move it back and everything would be as it was before. As Lee Jay says, anything you did to change the default behavior or appearance of Lightroom is stored in this file. Nothing regarding your images or what you've done with your images is stored in this file. Also, as explained in the article that Geoff provided a link to, you want to go into the Library folder that's in your User folder.

As to whether or not throwing out the preferences will help in this particular case, I can't say. It hasn't made any difference in my testing, but your milage may vary.
