Apple said that the T2 chip will prevent the hackers to listen to users via MacBook
After the presentation of the MacBook Air, Apple has published documentation on the security chip T2, which describes the capabilities of the chip, in particular, about his ability to disable microphone in laptop computers.
T2 Apple debuted the iMac Pro. Chip is responsible for storing fingerprints and encryption of SSDS. It can also inhibit the device if you are using a hacking code. MacBook Pro 2018 with T2 runs Apple’s voice assistant after the phrase “Hey Siri”.
Almost a year after the release of the chip, the company told him about another opportunity — the “hardware separation”. This feature disables the microphone in the MacBook Pro and MacBook Air 2018 2018 after closing the laptop lid. Deactivation is implemented at the hardware level, therefore, no program, even Root can’t activate the microphone when the lid is closed.
The front camera hardware is not disabled because “her field of vision completely blocked the lid is closed”, — the document says.
