I don't have that success rate. But what usually helps is enrolling a fingerprint twice a year. I guess it has to do with having dryer hands in the winter. So I typically redo a fingerprint near the end of autumn and at the end of spring and I am fine, so I am also near a 100% recognition rate.

I also only enroll one fingerprint, because I use a Magic Keyboard with Touch ID when I have the MacBook docked, the Touch ID sensor is always in the same position relative to my hands.

Regardless, I still hope we'll have Face ID on Macs one day.
