When you say you backed up to Dropbox, did you move your photos to the dropbox folder? What was your exact process for backing up your catalog?

I opened Lightroom, Library, All Photographs (under catalog), select All, File, Export as Catalog, Dropbox, save as, Export catalog. I've done this before but not with OXS. It worked but screwed up Lightroom. I had to reinstall from G-Drive backup. I had a problem with Silverfast also. They had to help me. They said it is a problem with OXS.

Just tried this and it works just fine. Certainly this is not a problem with OS X but something else. I can't imagine anything in OS X preventing doing this. There are actually many people that put their primary catalog in a dropbox folder and even this works OK.

It took hours for the almost 9,000 photos to download to Dropbox. Somehow Lightroom got compromised. How can you determine that it works okay with a quick check?! OSX seems to be creating problems in many ways.

I did a hundred images. They exported just fine. Took no longer than exporting a catalog to any other place on the hard disk. Uploading to drop box will take a while but that is just simply bandwidth of your internet connection. Most people have only a few Megabits of upload speed and when you have 1000's of raw files that is going to take days to upload. Just calculate: a typical 5 Mbps upload speed connection (very fast in the US, rather average in Europe and Asia) will make a typical raw file from a recent camera take 45 seconds to 1 minute. For 9000 images it will take 2 to 2.5 days therefore just to upload to dropbox. Nothing to do with your OS or your computer. You can shave a bit off by having an extraordinarily fast internet connection but even the very fastest connections are going to take many hours to a day.

100's of images aren't thousands!

You didn't address the problem. I have a fast computer and fast internet. It didn't take 2 to 2.5 days. The problem was what happened to Lightroom.
If you can't solve a problem it would be better if you don't answer!

I can't reproduce a problem. Please describe what actually happened. I can export a catalog to a dropbox folder just fine (it's just any folder to Lightroom so this should work indeed) Dropbox uploads this fine and I can't see any issue. So I can't figure out what is going on in your case. 

A fast internet (how fast? What provider) and a fast computer don't help much with this. 9000 images is about 200 GB of data! Lightroom will take a while to write this out to disk. It not only has to write the raw files but has the write the thousands of jpeg previews. I'd expect 5-15 minutes depending on the speed of the hard disk you are using. Then consider the upload to dropbox' servers. Only when you are on some fiber internet will this go with any appreciable speed. On typical cable internet this will take over a day to upload as upload speeds are generally only around 5 megabit/s. Commercial suppliers can go somewhat higher but 100 Mbit/s is exceptional. If you are lucky enough to have fiber internet available which can have upload speeds of gigabits/s you are in a different regime but you will still take 1/2 hour to an hour.

It may be just a coincidence that it happened while you were exporting to the Dropbox folder. Hundreds of thousands of people are using MacOS X and Dropbox every single day without any problems. Lots of people export catalogs from Lightroom in MacOS X without any problems as well. And in the end, your Dropbox folder is just another folder for MacOS X or for Lightroom.

That doesn't mean you don't have this problem, but it might be just a coincidence that it happened when you exported to the Dropbox folder. Maybe it would have happened just the same if you had chosen another folder. By pointing the finger at Dropbox or MacOS X, you may be doing yourself a disservice, because you've excluded the real culprit this way. Are your images and/or Lightroom catalog on an external disk or on the internal disk? If they are on an external disk, maybe a problem with the connection caused this.

You need to reread my "problem." I didn't say it was a problem with Dropbox. I did say it is a problem with OSX  because I also had a problem doing an update with my scanning program Silverfast. When I contacted them, they said they have been having problems with OSX!

I have no problems with Silverfast on MacOS X, and I don't see the connection anyway. Because you have a problem with Silverfast and MacOS X, why does that mean that any problem you have with Lightroom must also be caused by MacOS X?

You sound like a very argumentive person. Argue with someone else. Posting the problem I had was a mistake. I corrected it and hopefully it won't happen again!

Good to hear.
