I ahve a problem with Lightroom. Just upgrded the mac to Catalina, everything works great (for now) but Lightroom. Strangely, when I opened after the upgrade, by default, an other of my catalogues was active. I had to get back to my work catalogue, so I opened it. What I have right now are blank thumbnails on all folders. Only the metadatas are there, Lightroom sees the photos on my external harddrive but it doesnt show them. Please help me,
We are sorry about the experience with Lightroom after upgrading to macOS Catalina.
Would you mind sharing the version of Lightroom you are using by going to the "Help" menu, then "System info"? Is the catalog also saved on the external drive with your images? Do the images in Lightroom show missing when or you are not able to previews?
