Harmony and macOS 10.15 Catalina

With the release of macOS 10.15 Catalina, 32-bit apps such as MyHarmony will no longer launch and instead display an error message. For more information, see Apple's announcement regarding their transition to 64-bit technology.

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 an IR remote on MyHarmony, our new 64-bit app for Catalina, Harmony Desktop, is available for download. Harmony Desktop will support IR remotes only, 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., we will have a new app available in mid-November. In the meantime, you may continue accessing your Logitech Harmony Remote legacy software account by using a Windows computer or a Mac computer running macOS 10.14 or lower.

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
  • The current MyHarmony app on a Windows
  • The current MyHarmony app on a macOS 10.14 or lower
