Earlier this month, Apple unveiled its newest generation of MacBook Pros; all feature a significant bump in performance, a redesigned butterfly keyboard, the arrival of "Hey Siri" commands and a second generation of Apple's T-series chips.
The T2 chip works to improve performance and includes a Secure Enclave for encryption operations to secure the laptops and power Apple's TouchID as well as the Touch Bar.
