Apple Silicon Support

Garmin, please update Garmin Express and release a NATIVE arm64 release for macOS.

Apple hasn't sold an Intel Mac in *years* and it's beyond embarrassing that zero effort has been put into support Apple users.

Reminder, Apple users have more disposable income than any other type of computer buyer. Do the right thing and put some engineering effort into this growing platform!

    I switched from Polar to Garmin a long time ago because of Mac support. Looks like time has come to switch back to Polar, a European company.

    With Claude Code it would be a days work for an intern to create an ARM version ready for testing. Garmin is being absurdly obtuse about their plans.

    Mac OS 27 Beta 1 will not let you install Garmin Express anymore…

    I really hope Garmin finally release an ARM version.

    While a native ARM version is increasingly important and arguably overdue, the current x86 version should remain fully usable for the foreseeable future.According to Apple’s current guidance, macOS 27 will continue to provide full Rosetta 2 support, allowing Intel applications to run on Apple Silicon Macs through at least Fall 2027. Rosetta 2 is expected to be phased out starting with macOS 28, making a native ARM version a longer-term necessity rather than an immediate requirement.

    So, if that‘s the case; what is the reason that Mac OS is aborting the installation saying that a 64 Bit App is required?

    If macOS is specifically complaining that a 64-bit application is required, then the issue may not be related to Rosetta 2 at all. Rosetta 2 supports 64-bit Intel applications (x86_64), but it cannot run 32-bit code. That could indicate a legacy 32-bit component in the installer, a packaging issue, or simply a bug in the current beta. The error message by itself isn’t evidence that Rosetta 2 support has been dropped in macOS 27.

    Thanks for the additional explanation. 
    I actually checked the error message again and I remembered it wrong.

    It says: Garmin express requires a system with a 64 Bit Intel Processor.

    HW is a Mac mini M4 Pro.

    I just tested this myself on a fresh macOS 26 installation running in a virtual machine. I installed Garmin Express successfully, then upgraded that system to macOS 27 Beta 1. Garmin Express launches normally and appears to work without any issues.

    Interestingly, if I try to run the Garmin Express installer again on macOS 27, I get the same message you’re seeing about requiring a 64-bit Intel processor.

    That makes it look more like a bug in the installer or in macOS 27’s compatibility checks rather than an actual Rosetta 2 limitation. Since this is only the first developer beta, I wouldn’t be surprised if Apple fixes it in a later beta release.

    It's the installer's job to check whether your system fulfills the requirements of the application's requirements, the app itself doesn't do that (it assumes the installer did its job). If Garmin Express still starts, it means that the macOS beta you're using still contains Rosetta 2.

    This is not a bug, it always has been like this. (For example, when Samsung abandoned the printer market, their printers continued to work if you installed the drivers on an older OS, and upgraded afterwards. But the installer refused to install them on newer macOS versions - you had to patch the installer to get it installed.)

    Well, Yamaha is partnering with Garmin these days. It seems to me that regarding motorcycles, the market trend goes to built-in systems (just like in cars). However, many handheld devices like the GPSmap series depend on Garmin Express as well.
