Hi,

This thread was converted from an issue since this is not a bug with libfido2.

The version of OpenSSH that is bundled with macOS does not include the built-in security key provider (aka middleware). You can either build a standalone version of the provider yourself, or use OpenSSH from brew. You may find more details in the discussion following #464 (comment).

Let us know if you've got any more questions.
