Featuring Touch ID and Apple T2 Security Chip

MacBook Air now includes Touch ID — a fingerprint sensor built right into the keyboard — which allows you to conveniently and instantly unlock your MacBook Air, authenticate your identity, and make fast, simple and secure purchases using Apple Pay. To support Touch ID, MacBook Air comes with the Apple T2 Security Chip, which makes your notebook far more secure. The T2’s Secure Enclave protects Touch ID information and also ensures that software loaded during the boot process has not been tampered with. The T2 also features an SSD controller with on-the-fly data encryption for everything stored on the SSD. These allow MacBook Air to offer the most secure boot process and most secure storage of any notebook. T2 also features an always-on processor that enables “Hey Siri,” which lets you make requests to Siri with just your voice for things like finding files or opening an app.
