Hi，I also have some invalid plugin notices ,but not all.It's strange that it doesn't load all the plugins. I'm not quite sure about this at the moment. You can look at the previous post about how to run the plugins on new Mac, not sure if that's your problem.And the current user version does not seem to work withFile->Open menu. But it should not be necessary to use the plug-in to open the image. I failed to compile the plugin with qt5, but I also can load an image using the File->Open menu.
