What is alwaysonexclavesd?

alwaysonexclavesd runs on newer Apple Silicon Macs. It manages tasks that keep running even when your Mac is asleep.

What are exclaves?

Exclaves are sealed-off areas on the Apple Silicon chip. They are even more isolated than the Secure Enclave. Each one is a tiny, separate space where specific tasks can run with strong security.

What does it handle?

• "Hey Siri" detection (listening for the wake word)
• Find My beacon broadcasting
• Some notification handling
• Low-power background tasks

These features need to keep running when the main processor is idle or the Mac is asleep.

Why use exclaves for this?

Because they are walled off at the hardware level, the main operating system cannot peek into them. This matters for privacy. For example, the "Hey Siri" audio processing happens in an exclave that macOS itself cannot inspect.

Does it drain battery?

No. The always-on tasks use special low-power hardware on the chip. They are built to run all the time without meaningful battery drain.

Should you worry?

No. It is a normal Apple Silicon feature that lets your Mac do useful things while asleep, without giving up privacy or security.
