    Will this update prevent Catalog corruptions in DAM going forward?

    A Serval attempt to download this version returns an error. There is no specific message error other than saying there is an error and try again. I get the error approximately 1.3 GB into the download.

    Hi Mark - Are you referring to the issue with the incorrect synchronization of images and folders in the catalog after Big Sur updates? If so, the issue was fixed in Update 4 for Luminar AI. However, although the fix will prevent the catalog from corrupting after future Big Sur updates, it won't fix the catalog that has already been corrupted. Therefore, we recommend working with a new catalog. In case you need to finish important edits in the previous catalog, you can revisit it by clicking File > Catalog > Open (recent.

    Urm Skylum support, you've given Stan the Windows download when he's posted for support in the Mac area of the forum... 

    Also for some reason for every version of Luminar AI after 1.2.0, when I try to use Luminar as an Apple Photos extension - I click edit with -> Luminar and the following error pops up:


    Couldn't communicate with a helper application.

    Try your operation again. If that fails, quit and relaunch the application and try again.



    This is MacOS Big Sur, all versions up to latest patch.

    Nothing works to get it to open; I replace with the AI 1.2.0 version and it works fine again.

    I contacted Apple who stated that it is a problem with 'the vendors application'.

    updated to the new version and now the app won't load. it crashes after showing the flash of Lunimar AI and won't open. I tried deleting the catalogue and it started a new catalogue and worked for a day then failed again. I have deleted and shut down. restarted my Mac and downloaded again still won't work. I have had the program since it was released with no issues.

    Hi Colin Tume,

    Please try the following steps:

    • Hold down the Option key on your keyboard and start Luminar. Keep holding Option until you see a window with a list of available backups appear.
    • Select a backup that was created before you encountered the issue with the library and click Restore from Backup.

    Here is the video tutorial that may also be helpful:

    Let us know how it worked.
