It seems that Apple is working to add support for hardware tokens. It is all a bit vague, but the latest Safari Preview notes state [1]:

Added support for CTAP HID authenticators on macOS

It also gives me "Web Authentication" under "Experimental features" in the Develop menu.

Isn't that WebAuthn suppport? That is different from U2F.

Yes and no. U2F is basically the MVP of WebAuthn. If you're doing this today you should ignore U2F and just implement WebAuthn.

Firefox has WebAuthn out of the box, and there's a hack behind a pref to half-arse U2F if you still need that.

It doesn't, though. I've been trying to implement WebAuthn and, as far as I know, CTAP 2 doesn't work on any browser yet.
