However, according to Mark Gurman’s Power On newsletter, Face ID stands a higher chance of being introduced in the iMac or an external display first before the MacBook laptops. Apparently this has to do with the thinness of the MacBooks’ displays that could make it difficult to integrate the hardware.
With Apple’s iMacs being thicker, integrating Face ID and the TrueDepth camera system could be easier. According to Gurman, “At this point, the technology to embed Face ID into the thin MacBook displays doesn’t exist. So if Face ID comes to the Mac, I think it will be on an iMac or external monitor first. Apple has definitely been working on this, but time will tell if they launch it.”
That being said, Gurman does not confirm if the feature could launch in the upcoming iMac refresh, or if it could be a while before we see it, so don’t hold your breath waiting for Face ID in one of Apple’s upcoming Mac computers just yet.
