Problems Exporting from Lightroom Classic on macOS Catalina

If you do not have a LogiOptions ( I am starting to inquire about that before recommending the following)

Have you considered resetting the preferences file?

The preference file can get corrupted, resulting in odd behavior. Some people have a knee jerk reaction in thinking they need to uninstall then reinstall Lightroom Classic, maybe that could be called for, but it would be better to first reset the preference file.

Be aware that resetting the preference file will result in Lightroom Classic creating a new catalog instead if opening your previously opened catalog (normally) so make sure you know where your catalog is. 

Be aware the resetting the preference file will revert some settings in Preferences to defaults. So be aware of what you have changed, so that you can put those back the way you want them.

Inquiry, in your  plug-in's, do you have LogiOptions?

Known buggy plug-in, apparently can cause more problems than I for one originally knew about .

I have the same issue and have Catalina 10.15.2 + Lightoom 9.1. When I export from my external SSD (large drive where I store all my pictures) to my desktop projects folder internal SSD (smaller drive I use for projects) it hangs and requires Force Quit. However, if I move the first folder from external SSD to my internal SSD and THEN export to my desktop projects folder it works fine. Also, when I insert my SanDisk card into the card reader and try to export directly to the internal SSD it hangs. It seems to me that there's a problem exporting to and from external sources with this version of Mac and Lightooom.  If anyone has any ideas please let me know. Thanks. 

3. As you could export a few I doubt if this is a solution, but

Outside if LRC bring up Catalinas System Preferences, select Security and Privacy, select zorivscy, scroll down to Files and Folders, make sure LRC can access the hard drive (type) involved.

2. Test the hard drive you are exporting to.

1. Just a normal export to your hard drive? As opposed to using a publishing service.

Running 9.1, Catalina, can’t replicate that issue on this end. Probably need to run Disk First Aid etc, to make sure your drive is running properly. Could be a permissions or security issue but 9.1 does export multiple (I tried 7 images) just fine. 

Hi there,

We are sorry about the experience with Lightroom Classic while trying to export the images to an external drive.

You can add Lightroom Classic to the Accessibility list for macOS by going to the System Preferences, then Security and Pirvacy, then selecting the Privacy tab. Also grant permissions to Lightroom Classic under the files and Folders list, and under Full disk access. Once done, please restart the computer to check if that helps.

You can also try to reset the Preferences for Lightroom Classic using the steps mentioned here: https://helpx.adobe.com/in/lightroom-classic/help/setting-preferences-lightroom.html

Note: Please backup your presets, plug-ins, etc. before resetting the preferences.

Regards,

Which exact NUMBER version of Lightroom are you using?

Check the security settings on the drive and the destination folder.
