According to the latest macOS Big Sur beta, Apple is planning to bring FaceID to devices . It looks like we may soon see the secure face unlock option on Mac.

Back when Apple introduced its FaceID biometric authentication technology for the iPhone X , a code snippet named “ PearlCamera ” was found in the iOS update , and now developers have found references to “PearlCamera” in macOS Big Sur Developer Beta 3.
As 9to5 Mac reports, the macOS beta also revealed codes like “FaceDetect” and “BioCapture” that indicate Apple is working on introducing the biometric face unlock option to MacBook devices.
Of course, the whole project is still in the testing phase and it is very likely that Apple will need a lot of time before finally bringing it to Mac devices.
FaceID will certainly add an extra layer of security to MacBooks and make unlocking the devices even more convenient for users.

One of the best applications of this technology could be seen on the iMac, as the MacBook Air and MacBook Pro already have the TouchID biometric authentication system integrated into their built-in keyboard. Since the iMac doesn't have built-in keyboards, FaceID would be particularly useful on them.
The addition of the Neural is definitely something that will help with the integration of FaceID, as it is one of the main components for analyzing facial data. Recently, Apple announced that it will stop using Intel and start using its own.
As speculation suggests, FaceID could be released alongside the first MacBook to use Apple Silicon.
