你知道吗？从 2019 款 Macbook 开始，合盖将会导致麦克风被硬件断联
今天翻手册的时候无意中看到的，原来 T2 芯片还有这个功能
「所有基于 Apple 芯片的 Mac 笔记本电脑 和 所有基于 Intel 芯片且搭载 Apple T2 安全芯片的 Mac 笔记本电脑 都具备硬件断联功能，该功能会在机盖合上后停用麦克风。这旨在防止任何软件（甚至是拥有 macOS root 或内核权限的软件以及 T2 芯片或其他固件上的软件）在机盖合上后启用麦克风。」
「2020 年及之后推出的 iPad 机型也支持硬件麦克风断联功能。将符合 MFi 标准的保护壳连接到 iPad 并合上之后，麦克风会在硬件层面断联。」
