What is it?
What it is
A native SwiftUI system monitor for Apple Silicon that tracks CPU, GPU, Neural Engine (ANE), Media Engine, memory bandwidth, and other low-level metrics with a menu-bar suite and Process Inspector.
Why it exists
To provide detailed, Apple Silicon-specific metrics (ANE, Media Engine, memory bandwidth) that traditional monitors like Activity Monitor lack, enabling better understanding of on-device AI and media workloads.
Who should use it
Teams building with Swift who want an open-source, self-hosted option.
Who should avoid it
Teams that need a fully managed SaaS with enterprise SLAs out of the box.

FAQ
How do I install SiliconScope?
Download the latest DMG from the releases page and drag SiliconScope into Applications.
What are the key features of SiliconScope?
Process Inspector, Replay recording, AI Workload view, per-unit sensors (temperatures, power), and per-metric menu-bar items.
Why isn't SiliconScope available on the Mac App Store?
It uses private APIs (IOReport, SMC, HID) that require notarization without sandboxing, making App Store distribution impossible.
How can I contribute to SiliconScope?
Submit pull requests via CONTRIBUTING.md, especially by verifying per-chip temperature sensor keys for M2–M5 chips.
What is the Replay feature?
Record all metrics to a .ssrec file and replay the dashboard with scrubbing, speed control, and playback options.
Do I need to build SiliconScope from source?
No, download the prebuilt DMG. Building requires Xcode and Swift, but the DMG is ready to use.
