Garmin Express 7.29.2.0 NOT working on macOS Tahoe 26

I can't use Garmin Express on my macOS Tahoe 26.6.2 to sync my Garmin Forerunner 955. I need to know whether or not Garmin Will update the Garmin Express app for macOS Tahoe 26.6.2 and later. 

  • 7.29.2.0 is compatible with Tahoe.

    Another user had an issue and Garmin's suggestion was to remove and reinstall Garmin Express.

    There has been no answer from the user.

  • I found a solution: The issue was the Rosetta/permission/background-service environment, which prevented Garmin Express from completing its device handshake; so in macOS 26, on terminal

    softwareupdate --install-rosetta --agree-to-license

    That command installs (or verifies) Rosetta 2.

    The permission adjustment was separate—it was done through System Settings → Privacy & Security.
