The latest Mac models all come with the T2 security chip. But what does this chip do, and could it cause more problems than what it solves?
T2 Security Chip
The T2 is Apple’s second generation of its security chip. It is a combination of several hardware controllers; all put into a single piece of silicon. They call it a security chip since it’s the main reason for the secure boot function. It validates the entire boot processor verifies that Apple approves only the boot loader and operating system. It also only allows approved drives to launch the OS.
In addition, it is responsible for encrypting the information on the drive. Before its introduction, encryption was handled by the CPU. By moving this task away from the CPU, it frees up resources and boosts the performance of the overall computer. On the Macs that come with fingerprint scanners, the T2 stores and verifies the fingerprints when scanned.
The chip also has other responsibilities. For example, it manages any behavior relating to battery, charging, power, fan speed, and other internal sensors. Apple also assigned autoprocessing to it. While the sound on the new Macs is great, professionals debate how much it has to do with this chip.
Potential Problems With The Security Chip
There is one major issue with the chip. Apple confirmed back in 2018 that the T2 blocks some third-party repairs. This forces Mac users to use Apple or Authorized Service Providers for repairs. Secondly, by locking down the boot process, users cannot install other operating systems like Windows or Linux.
Future Of The Chip
We may get updated iterations of the chip in the future, but the purpose of the chip is likely to stay. It enables Apple to have more control over the device and keeps its customers in its ecosystem. However, Apple is in the process of creating its processors for its computers, so the T2 may get integrated into the ARM processor.
