MyHarmony and Catalina

On macOS 10.15 and above, 32-bit apps such as MyHarmony or Logitech Remote Software will no longer launch and instead display an error message.

If you have a remote that doesn't use a hub on MyHarmony, our new 64-bit app for Catalina, Harmony Desktop, is available for download. Harmony Desktop will only support remotes that do not have a hub; including Harmony 200, 300, 350, 650, 665, Touch, Ultimate One, and 950.

If you have a remote on Logitech Harmony Remote legacy software, such as the Harmony 880, 900, One, 1000, 1100, etc., an updated version which will work on macOS 10.15 Catalina is available in the faq section of our downloads page.

When using macOS 10.15 Catalina (or higher), if you're using Harmony Hub or a hub-based remote such as; Harmony Elite, Companion/Home Control, Smart Control, Ultimate Home, or Ultimate, you can continue to use:

  • The Harmony mobile app on iOS or Android
