@gruber wrt https://daringfireball.net/2026/03/apple_enclaves_neo_camera_indicator - i wonder if ambient light sensing is done via an exclave connected to the camera instead now, rather than ALS. explains why it can do it without one, and it'd also indicate why there's no hardware camera light (if the exclave is using it without telling the OS)

“What that means in practice is that even a kernel-level exploit would not be able to turn on the camera without the light appearing on screen.”
