Why MacBooks Don't Have Face ID

Apple's Decision to Leave Face ID Out of MacBooks: A Technical Dilemma

In 2017, Apple replaced Touch ID on iPhones with face ID, revolutionizing the way we authenticate our devices. However, one would think that the same technology could be applied to MacBooks, given their larger screen and more spacious Notch design. But surprisingly, this hasn't happened yet, leaving many users wondering why.

The main reason for Apple's hesitation in incorporating face ID into MacBooks is due to technical limitations. While it may seem like the MacBook's Notch has plenty of space, its depth is actually quite shallow, measuring only around 3mm thin. In contrast, iPhones have a deeper notch that measures approximately 7.8mm. This shallowness is crucial because it allows for the accommodation of components such as higher quality camera lenses, infrared cameras, and a DOT projector - all necessary for face ID to function.

These components simply cannot fit within the 3mm enclosure of a MacBook's lid, which is why photos from these devices are often blurry. Apple has two options to address this issue: either make the MacBook's lid twice as thick to accommodate the required components or leave out the feature altogether and rely on Touch ID instead. The latter option would not only be cheaper but could also be more practical.

In 2021, Tom Boger, Apple's vice president of Mac and iPad product marketing, made an argument in favor of leaving face ID off MacBooks. When asked why the feature wasn't included, Boger claimed that Touch ID is more convenient on a laptop because users' hands are already on the keyboard. This reasoning sounds reasonable at first glance, as it implies that a face ID scan could be confirmed by pressing a key - similar to how Apple Pay works on an iPhone. However, this argument doesn't hold water when considering how easily face ID can be confirmed on a MacBook.

In reality, face ID scans can be just as easy to confirm as Touch ID scans. The recognition process would happen faster, and users could use any finger to confirm the scan - not just one registered fingerprint. This means that while Apple may not want to admit it, they haven't figured out a way to include face ID in MacBooks without compromising on performance or aesthetics.

Only time will tell if Apple is able to overcome these technical challenges and successfully integrate face ID into their MacBooks without sacrificing any of the device's performance or usability. Until then, users will have to rely on Touch ID - or explore third-party alternatives that can provide similar facial recognition capabilities.
