I cannot export images in Lightroom CC so that they actually appear in my Mac Finder (OS 10.10.5). Imports from Finder folders without a problem. Goes through the Export function with no error messages. Finder itself is unchanged; the exported images are not there. If I re-export, I get the error that I'm about to overwrite existing images. Have tried relaunching Finder, restarting computer, etc., nothing is working. Has anyone had this issue?
