LR Classic not working after Mac OS Updates

Lightroom Classic issue after Mac OS Updates:

Software: Lightroom Classic
OS: Mac OS Sequoia 15
Issue: Catalog freezing; Sync would not progress; Upon import, could not locate/existing Collections not displaying; endless/frozen Optimize Catalog

I've been having issues with LrClassic ever since the big Mac OS and Adobe updates in October 2024. Here are the issues I'm running into lately!

1 - Catalog Freezing: When I open LrClassic, it freezes for 2-3 minutes completely before I can do anything. Once it is unfrozen, if I want to import images to my catalog, I cannot add anything to existing collections (they do not display, the list is empty).

2 - Sync does not progress:

Sync is just stuck spinning, nothing syncs.

3 - Optimize Catalog does not work:

If I try to optimize the catalog, it sits infinitely and I have to force quit Lightroom.

I spent 4 hours on the phone with Adobe, and they got it working once we copied my catalog into a new catalog. And then Mac released a security update and I’m right back where I started. Please help! I’m behind on jobs and I pay way too much for this software to not be able to do my work!

Hi, I've just installed the updated Lightroom Classic on a new MacBook Pro running Sequoia 15.2. It freezes on the opening screen when "Reading preferences" and won't do anything. Yesterday, before the newest Sequoia and LR updates, it simply crashed as soon as I clicked on it. Someone please help.

I am having the exact same problem described here. I have uninstalled Classic and then done a clean re-install. I have also reset my preferences. No luck. Oddly, this problem occurs on my M4 Mac Mini but NOT on my M4 Pro Mac Mini. Not sure if that is relavent...Very, very frustrating.

The problem is between Mac and Synology using SMB. Mac and SMB have been a known issue of instability for a long time. With a Synology MAS and Mac it just doesn't work it crashes.

After weeks of struggling with this I set up a share on my Synology NAS and turned on NFS. Transferring files between Max Sequoia and Synology using NFS works fine.

I'm sure at some point the two of them will get together and fix SMB but if you just engage NFS which you can Google how to do or use chat GPT for instructions.

I have been using the NAS with the current SMB setup for several years. Why all the sudden do I need to switch to NFS?

Hi @ovi_4698!

Could you share more info? Have you checked for any available OS updates? Are you trying to install the apps via Creative Cloud or from the web?

Thank you! Alek

Yes, I have checked for updates.

I have tried installing through Creative Cloud. I might try through web.

I called Adobe a few days ago to check on status and the chat person said someone would call me between 24 and 48 hours to update me. Not a call …..

Hi Rikk, thanks for your kind answer. I tried your "spell" but LR Classic still freezes upon "Reading Preferences" as you can see from the attached screenshot. My MacBook Pro is brand new and I don't have any old catalogs in it or preferences, etc.

I would use the new version of Photoshop instead but that's problematic too because it won't open my Sony ARW files. It says it doesn't recognize them.

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Does the behavior continue after resetting the preferences?
