Since upgrading Mac to Catalina both Macs in the house are experiencing Lightroom spooks. Mine is minor: printing comes out really really dark. My wife's is critically impossible: 'Import' will not recognize files or folders, on SD card or even on Finder. Photoshop still sees these files and imports them. But in Lightroom, while in 'import' the navigation pane shows SD card as empty, and Desktop folder as being empty of files and sub-folders even though these show up normal on the computer's finder. We've already had one update of Catalina. To no avail. Is Lightroom working on this?
