A sudoless Apple Silicon system monitor — a native SwiftUI dashboard and a full menu-bar suite — with first-class ANE (Neural Engine), Media Engine, and memory-bandwidth tracking that Activity Monitor and terminal monitors don't surface.

Born from wanting to see how on-device AI and media workloads drive the Apple Silicon accelerators — and grown into a daily-driver monitor that can stand in for iStat Menus.

*New in 4.0 — it watches your other machines too. A headless Mac mini, a Linux GPU box under the desk, a rented cloud instance: run a small agent there and it joins the same dashboard, over an encrypted, paired connection. Remote Macs keep the full treatment, Neural Engine included*.

One M1 Max on macOS 27 under a real on-device AI load — [Spectalo](https://spectalo.calidalab.ai/) running its Core ML models. The workload classifier reads ANE (CoreML), and the Neural Engine is 100 % active, moving 16 GB/s — measured cluster residency, so it stays live even on macOS 27, where this chip's energy counters update only about every half hour. The GPU is at 100 % and 36 W, memory bandwidth is 306 GB/s against the chip's 400 GB/s ceiling (bandwidth-bound), and the header's system 105 W is the whole Mac's draw. Colour is spent only where something needs attention — here, red on CPU and GPU temperatures above 90 °C — and neutral everywhere else. The bar along the bottom is Replay (new in 3.0): every metric is recorded, so you can scrub back through a session like a DVR.

Menu bar — every metric, iStat-style

Pin any card to its own menu-bar item — CPU · GPU · Memory · Network · SSD · Sensors · Battery — each with a live glyph and a rich dropdown. Every item chooses its own style (bars · history graph · two lines · single value · icon) and which readings it draws, so a metric can even appear twice: CPU as bars and as a graph. All sudoless.
