Patently Apple posted a patent report back in March 2020 from Apple regarding Face ID for Future Macs. Apple revealed the Notch for Macs before it was brought to market, as noted in the patent figures below. Over a year later, Bloomberg's Mark Gurman noted in his weekly newsletter that Apple would be bringing Face ID to makes in a couple of years. You could read the details of the 2020 patent report here.

Last Week the U.S. Patent and Trademark Office officially granted Apple a patent relating to Touch ID for Macs and other devices. This particular patent stretches all the way back to 2008, just a year after the iPhone was released to illustrate that Apple envisioned this feature very early on – as in 15+ years ago.  

Apple's patent FIG. 1B below illustrates that a Mac Desktop was one of the original targets along with the iPhone (not shown): FIG. 4 is a diagram of a computer processing environment including various applications or routines running within a personal computing device according to an illustrative embodiment of the invention.

Apple's patent evolved since its original 2008 patent application with at least five patent updates. Last week's granted patent stems from a 2020 continuation patent filing wherein Apple filed a whopping 54 new patent claims. The average Continuation patents adds 20 new patent claims, so this was extraordinary.

While the new claims cover user authentication to access a Mac, the claims also notes that facial recognition (Face ID) would be used to access a user's email. The validation would also work with user's with one or two eyes (so Cyclops can use it too!).
