Face ID made its debut back in 2017, slowly showing up in the iPad Pro lineup in 2018. What about Face ID for Macs? Well, that’s a future Apple will most certainly be aiming to achieve and according to a new patent filing, the time to get facial recognition for Apple’s desktop and notebook range might be approaching. To remind you, Apple filed for a patent for Face ID for its Macs back in 2017, even before it made its way to the iPhone X. However, since iPhones and iPads are usually in-line to get these features first, it probably made sense for Apple to do the same for Face ID.

Apple has now been granted a patent for a more advanced version of Face ID. Firstly, quite like the iPhones and iPads, the system will authenticate users but additionally, it will also act proactively to determine if a human being is in close proximity when the device is in the sleep mode and if that is the case, it will decide whether the person in question is the owner of the device. If the answer is in affirmative, the Mac will be unlocked, or else it will remain in its reduced power state.
