It's better to do feature-detection when possible than try to figure out what versions a user is running. User agent strings lie and sometimes features get backported to older versions after they've shipped on newer ones. For the question you're asking WebAuthn supports the method PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable()

If you're a user it's useful to know passkey support requires Ventura or Sonoma versions of macOS according to Apple's support site. If you're a web developer use the above method of feature detection.
