Logging into your computer with your fingerprint isn’t new, but it still makes me a little giddy when the MacBook Pro’s Touch Bar appears, glowing brighter than the backlit keyboard. I follow the Touch Bar’s direction, and like magic I’m into laptop. It’s instantaneous. The fingerprint reader is one of the smallest improvements to Apple’s all new MacBook Pro with Touch Bar, but it might just be my favorite. There, hidden beneath the MacBook Pro’s flashiest gimmick, is something incredibly functional and natural to use.
