For instance, the Full Security mode, set by default, requires a network connection to verify the operating system’s integrity, the latest version of MacOS, and “verifiable” software at boot. This tool also provides three settings - full, medium, and no - to control how strict the T2 chip will be during boot. With this tool, you can password-protect the firmware and enable/disable booting from external devices. But you can control the secure boot process by pressing “Command-R” to access the Startup Security Utility.

What this means for MacBook Pro owners is that their device isn’t susceptible to low-level attacks, as only verified, trusted software will launch during the startup process. It will even scan the integrity of Boot Camp Windows-based volumes. This process includes scanning the firmware, the system kernel, kernel extensions, and more. It monitors each step and cryptographically signs an approval so that the startup can progress to the next stage. This is why you should frequently make backups using Time Machine.Īpple’s T2 chip also provides what Apple calls a “hardware root of trust,” meaning that the chip handles the startup process. But that also means you can’t move the SSD to another MacBook Pro should your current model suffer catastrophic failure. Moreover, if the SSD were to be removed, a hacker still won’t gain access to the stored data. This method is great in that data cannot be accessed without your personal key. Owners gain access to the data through Apple’s FileVault platform that provides your own personal key.
This process uses 256-bit AES encryption and security keys unique to that specific MacBook Pro model. “It also consolidates many discrete controllers, including the system management controller, audio controller, and SSD controller, into one.”Ī deep-dive into the chip shows that it includes a built-in hardware encryption engine that encrypts all data stored on the MacBook Pro’s SSD. “The Apple T2 chip includes a Secure Enclave coprocessor that provides the foundation for secure boot and encrypted storage capabilities,” the company states.
The updated models include the T2 security chip first introduced in 2017’s iMac Pro providing a secure boot, encrypted storage, live “Hey Siri” commands, and more.
