Question

Lightroom will not sync even after letting it run for days

Subject: Lightroom Desktop (v. 9.3.1 from the mac app store running on a Mac Studio with M2 chip) Stuck Syncing for Days – Cloud Storage Never Updates

Hello,

I'm having an issue with Lightroom Desktop on my Mac that I have been unable to resolve.

For several days, Lightroom has been stuck in a syncing state. The application appears to be running normally, but the Cloud Storage panel continuously shows:

  • Cloud Storage: Calculating...

  • Syncing Items spinning indefinitely

The software never completes the sync process, even after being left running overnight and for multiple days.

Things I've already tried:

  • Leaving Lightroom open for extended periods

  • Confirming my internet connection is stable

  • Restarting Lightroom

  • Restarting the computer

The attached screenshot shows the current state of the application.

Could you please advise:

  1. How can I determine what item(s) Lightroom is attempting to sync?

  2. Is there a way to view a sync error log?

  3. Are there known issues that cause Cloud Storage to remain in a perpetual "Calculating..." state?

  4. Is there a safe method to reset the sync process without risking loss of local photos or edits?

  5. Are there any Lightroom diagnostic files I can provide to help troubleshoot the issue?

For reference:

  • Lightroom Desktop (please advise if you need the exact version)

  • macOS (please advise if you need the exact version)

  • Issue has persisted for multiple days

Thank you for any assistance.

    ​@mjh097, thank you for sending the information via DM. First, a quick note: the username you used for the other ID that you used to send the DM to me appears to contain your email address. For privacy reasons, I’d recommend changing your username so your email address isn’t publicly exposed.

    Regarding the diagnostics log issue, if Lightroom reports that the file cannot be located when generating the log, it may lack permission to write to the Desktop or access certain folders.

    Could you please check the following on macOS:

    System Settings > Privacy & Security > Files & Folders

    Make sure Lightroom has access to:
    • Desktop Folder
    • Documents Folder
    • Downloads Folder
    • Removable Volumes (if applicable)

    If Lightroom is not listed there, please also check:

    System Settings > Privacy & Security > Full Disk Access

    • Click the + button
    • Navigate to the Applications folder > Adobe Lightroom CC
    • Add Adobe Lightroom.app
    • Enable Full Disk Access for Lightroom

    After granting permissions, restart Lightroom and try generating the diagnostic log again:

    • Preferences > Account
    • Hold the Option key
    • Click Sync Issues Report
    • Generate Log

    Regarding the "Calculating..." sync state: A few things to check while we investigate:

    •  Do you have any very large files (videos, panoramas, or RAW files over 200MB) that may be stuck in the upload queue?
    • While your connection is stable, some corporate firewalls or VPNs can block the specific ports Lightroom uses for sync. If you're using a VPN, try temporarily disconnecting or switching to Mobile Hotspot or to a different unmanaged Wi-Fi network.

    Once you’re able to generate the diagnostics package, please send it to me via DM, and I’ll share it with the team for review.

    Best regards,
    Anshul Saini

    Hi Michael,

    Thanks for reaching out and sharing the detailed diagnostic information about the issue. To further help you out, could you please share your Adobe email ID with an active subscription via DM with me?
    Also, ensure that you are using the latest version of both Lightroom (v9.3.2) and the Creative Cloud Desktop app (v6.9.1.1), which are fully updated.

    Please share the logs with me by going to Preferences > Account, holding down the Option key, and then clicking on Sync issues report. Next, click Generate Log, then click Show in Finder when it's finished. A file named LrDiagnostics.zip will be created on your Desktop. Please share that with me via DM.


    Thank you again for taking the time to document and share the issue.

    Best regards,
    Anshul Saini
