Different references found in the macOS Big Sur code seem to augur the expected arrival of Face ID to the Mac , although it would not be soon.
People from 9to5mac have discovered references to FaceID for Macs in the third developer version of macOS Big Sur , where codes such as “PearlCamera” have appeared, the internal name with which Apple identifies the TrueDepth camera, which is one of the components responsible for Face ID. References to “FaceDetect” and “BioCapture” have also been found in the aforementioned beta, which have also been similar codes to those used in iOS previously to refer to Face ID.
If true, Apple would already have advanced work to bring a 3D facial unlocking system to Macs , although it is likely that they require the new processors prepared by those from Cupertino.
In any case, it seems that this feature would be in a very early phase of development since it would require special components that Mac do not currently have.
And is that no Mac currently has the TrueDepth sensor for Face ID , to which we would have to add that it would require the Neural Engine, one of the components that are present in Apple’s Ax Bionic processors. It should be noted that currently the only biometric authentication option present on Mac is the fingerprint sensor that uses a custom T2 chip.
It is likely that the feature of Face ID on Macs will reach the new computers with Apple Silicon with ARM processor that will begin to be launched in the market later this year.
