Possible raggie interpretation: He has a MacBook, paid for the TouchID feature, but the computer keeps asking him to type his password, rendering the extra feature useless.
If this is the case, the TouchID needs to be setup and learn your fingerprint. I program mine with more than one fingerprint.
Also, there might be a way to have the system learn your fingerprint more reliably. At least on the older iPhones with the physical home button, keeping the settings screen up with the TouchID allows for “refinement” of the programming by lightly resting the programmed finger in the button and the system highlights the corresponding print, acknowledging more data on that print.
