Unable to start Garmin Express for Mac on macOS Sequoia

am I wrong or is Sequoia just annouced and not yet released?

macOS Sequoia Developer Beta

did you expect a beta OS compatible with a not errorfree Garmin express??

No, but I am reporting it so that it can be made compatible sooner rather than later

unfortunately the forum is the wrong place to report errors and problems. Garmin will not respond. I'd recommand to contact the support. additionally Apple support. anyway thanks  so I will wait updating to Sequoia until the issue is solved (may take some time)

You're reporting the issue to users, not Garmin.

I'm having the same issue on the beta. If I would have known this would happen I would have waiting but oh well. Hopefully it will be resolved sooner than later.

Nobody knows what will happen to any app when loading any beta OS, never mind the first public release beta. It’s always a lottery. If you’ve loaded the beta MacOS then perhaps it’s safe to assume you have a backup you can rollback to in the meantime. Garmin are under no obligation to sort this out until the OS is publicly released in a few months. Can you wait that long?
