A source who has provided reliable information in the past has informed us that the new MacBook Pro models, expected to be launched in the fall, will feature a Touch ID power button as well as the previously-reported OLED touch-sensitive function keys.
The KGI note which first reported the OLED function key display also suggested that the new MacBook Pros would offer ‘Touch ID support,’ but did not contain any specifics. Incorporating it into the power button would clearly make sense, allowing the same one-touch process to power-on and authenticate as is possible with the Home button on current iPhones. Resources spotted in macOS Sierra also hint at Touch ID on future Macs.
