Lightroom - Unable to move some photos (already searched) macOS

Report · Dec 23, 2019

I've searched around and haven't found exactly how to solve this. Any help would be greatly appreciated!

My machine froze HARD in Lightroom while editing, computer crashed (brand new top of the line iMac).

I am logged into the same account on my phone as well and share photos between the two. Both devices say that all files are synced.

Hi Cameron,

The error message indicates that you have a malformed catalog.

Recovery steps depend upon your Catalog’s current Sync Status.

Fully-synced:

If you believe you are fully-synced, or if you have yet to place any assets in Lightroom Desktop, the local MCAT file can be renamed, allowing for the sync of your catalog information down from the cloud, restoring your local catalog.

Synced Instructions:

Make sure you have a good internet connection
Close Lightroom
Locate the MCAT file and rename it from “Managed Catalog.mcat” to “Managed Catalog.old”.

Windows:

Users>username>AppData>Local>Adobe>Lightroom CC>Data>Catalog ID string>Managed Catalog.mcat

Mac:

Users>username>Pictures>Lightroom Library.lrlibrary
Right-click on file and select “Show Package Contents”
Navigate to: > Catalog ID string>Managed Catalog.mcat

Launch Lightroom
Allow Lightroom Desktop to fully sync

The Lightroom catalog should now sync from the cloud to your local desktop. This may take some time. Checking with the Cloud icon will update you on the progress. When complete, you will have a new “Managed Catalog.mcat” file. Retain the old MCAT file until you are satisfied of the recovery then the Managed Catalog.old can be deleted.

Not Synced:

If the Lightroom application is not completely synced there are two scenarios:

Scenario 1:

All original images were imported from Lightroom Mobile, Lightroom Web, or were synced from Lightroom Classic as Smart Previews.

Follow the Synced instructions to restore your Lightroom Desktop catalog

Scenario 2:

Some or All original images were imported via the Lightroom CC desktop application.

Locate the originals:

Windows:

· Navigate to: Users>username>AppData>Local>Adobe>Lightroom CC>Data>Catalog ID string>Originals

Mac:

· Users>username>Pictures>Lightroom Library.lrlibrary

· Right-click on file and select “Show Package Contents”

· Navigate to: > Catalog ID string>Originals

Make a backup copy of originals for possible missing files to be reimported - if necessary.
Follow the steps for Synced: (show above)
Allow Lightroom Desktop to fully sync
Import any images from the backup copy made earlier that are missing from the restored MCAT

Previous Edits made to unsynced assets which are reimported will not be recoverable.

Let us know if it helps.
Regards,
Sahil
