It's working on my Mac, too. macOS 10.12.5 You might have a corrupted preference file. Try deleting all of the "com.Google." and "Nik Collection" preference files you can find. (Back them up first if that makes you feel more secure.) Do the other Nik plugins work okay? I assume you have tried reinstalling the plugin... Myron
