I cannot use this software. I was super happy Logi was finally bringing something new but I'm completely frustrated. It does not work properly with my Mac. Every time the software is on, my cursor movement gets stuck EVERY SECOND on my external monitor. Then, I close the app and it works fine but guess what? The app re-opens on its own!!!! And then I'm unable to move my cursor properly again. With this level of readiness (or no readiness), it should never been launched.
