We are not saying that this has to be done immediately and neither that the following Macs are going to have the great Face ID functionality integrated, but it would be time for Apple to integrate it after being available first on iPhones and then on iPad Pro.
The Mac would be the next to be updated in this sense and the MacBook Pros have already added Touch ID for a long time, so we hope that the company will definitely launch Face ID in them. A pop-up window to log in to iCloud in the beta version tells us to log in with Face ID, so Can we think it's close?
Face ID integration is coming to Macs, but we don't know when
Logically, this functionality is one of those that will end up reaching all Apple users on most devices and Macs would be the next "in order" to implement it. For space to add the sensor of course it is not, so we do not know what the company is waiting for to launch this new functionality.
They may wait for the moment when they change this current keyboard format called butterfly, but this is still a rumor so we cannot confirm that this will be the case. Implementing Face ID, Apple would actually facilitate access to the computer itself once it is unlocked for the first time, just as we do with the iPhone from the iPhone X. Logging into iCloud, the App Store or any web page thanks to Face ID would be much faster , safe and productive, in addition Apple today has this function really well implemented in its idevice as to expand it on your devices that still don't currently have it.
