Issue: Lightroom Classic import stalls when a case-sensitive duplicate file name is encountered in the same folder.

 

Lightroom Classic Version Number: 11.4 build 202206021307-2f136917

OS Version Number: MacOS Monterey 12.4

 

Steps to reproduce:

1. Create files in the same folder named IMG_123.jpg and IMG_123.JPG (file names should be identical spelling but different case)

2. Attempt to import all files in the folder or Synchronize Folder on an existing folder containing said files

 

Expected result: Lightroom successfully imports all files or alerts the user to duplicate file names

Actual result: Lightroom import stalls and the progress bar freezes until the import is manually cancelled.

To clarify in step 2, this is using the "Add" import method.

Another apparent bug is at Apple. Is not MACOS file name case insesitive, to MACOS IMG_123.jpg and IMG_123.JPG should be seen as the same file and not allowed to coexist.

While not default, APFS supports case sensitive modes. https://support.apple.com/guide/disk-utility/file-system-formats-dsku19ed921c/mac

It's also possible to mount other filesystems and connect to network storage systems that support case sensitive filenames on MacOS.

LR nominally supports case-sensitive volumes for storage of photos and catalogs -- you just can't install LR on such a volume:

However, there have been bugs reported about case-sensitive volumes before, and knowing the plugin-visible internals very well, it wouldn't surprise me if you're tripping over another bug.

 

But I'm not able to reproduce your steps on LR 11.4.1 / Mac OS 12.4  importing from a volume formatted Mac OS Extended (Case-sensitive, Journaled).  See the attached screen recording.

 

What's "curious", though, is that LR displays both file names in upper case and reports such to plugins that access the file name (indicative of confusion internally).
