AFAIK Apple refused to implement attestation, so you can't realistically enforce it. Who knows how long that one is going to last, though.

It’s incorrect - Apple has in fact implemented attestation as can be seen in https://github.com/lbuchs/WebAuthn.

I'm not familiar with all this, but when I run the demo page (https://webauthn.lubu.ch/_test/client.html) on macOS 13.4.1 with Safari (Firefox doesn't work) I get "none" for the apple attestation.
