There's been some speculation that Touch ID could make its way to the Mac, notably on MBPs. What does everyone here think about the likelihood of this happening? And if you think it'll be implemented, when and how? My guess would be in the Skylake MBP release (so late 2015 or early 2016) where an updated design would coincide with introducing Touch ID. I see three possibilities for how it'll be implemented: In place of the power button (most likely). Somewhere on the outside shell, perhaps where the screen lid is opened from or on the side where the ports are. Would be convenient for using in clamshell mode with an external monitor. Integrated in the trackpad. This seems least likely because of the amount of engineering involved. But if the iPhone ever has Touch ID integrated in the display (no more Home Button!), a possibility for iPhone 7 in 2016, then perhaps the same could be done with the trackpad (which is glass).
