Feb 07, 2020 As of macOS 10.15 Catalina, 32-bit software such as MyHarmony and Logitech Harmony Remote Software will no longer run and will require an update for it to work.If you’re using a hub-based remote, you will need to use the Harmony App on your iOS or Android device. Logitech's website has a note on the Download page regarding Myharmony and Catalina. They provide a link to a download for 'Harmony Desktop' app that supposedly runs on Catalina. The link takes me to the same download page as before and the resulting downloaded file is the old 32-bit.
