Thanks for reaching out. If you can clarify a few things for me, we can get to the bottom of this.
Could you please share the specific version of Lightroom Classic from Help > About Lightroom Classic and the particular version of macOS? Has this happened recently since an update of the macOS or Lightroom Classic?
Does the image open up when you right-click it and select 'Show in Finder? Where is the original image stored on an internal or external drive? Where are you trying to export the pictures to?
Does the issue with export happen with specific files or formats? Could you please confirm if you are using any Export presets?
If you are keeping original images on an external drive or exporting to an external drive, try this:
Search for Disk Utility from Finder's spotlight search or magnifying glass.
the lightroom version is 11.4 ans my mac version is montery 12.4
the export from my images doest work after the update from lightroom. i think there is no problem with the mac.
i want to export my images from lightroom to my desktop and always when i wnat to do this there is a error and i cant export my images. when i go 2 versions in lightroom back there it works.
