As per screenshot, the Garmin Express installer does not work on macOS 27 with Apple silicon hardware. The installer appears to contain a hard check for intel based hardware, which Apple has not shipped in over 6 years.
It looks like a fix has been released for this with version 7.29.3 for Garmin Express.
If you are still experiencing this after updating to 7.29.3, please create a new thread so we can get those addressed…
I created a script that will Install Garmin Express on macOS 27.
Copy and paste this into Terminal and run:
bash -c "$(curl -fsSL https://gist.githubusercontent.com/sevenlayercookie/ba26f8b1fffc5143eb3046bdb8c0695f…
You’re correct - macOS27 is out of beta, Garmin has known for some time their GE installer is not compatible with the new OS, yet they still have issued an update. We should not be jumping through hoops…
This is 2026 were developers must be committed to bring up to date software. That is what we customers expect.
the interface of GE is also completely outdated. truly unbelieve as if I am sitting behind…
latest Garmin Express installer directly from Garmin, removing any incomplete previous installation, and restarting the Mac before attempting the installation again. If the installer still fails, sharing the exact error message, Mac model, and macOS build number would make it easier for others to identify the cause.
