v1.2.0

First public release, under MIT OR Apache-2.0. siltop grew up as a private project
(1.0 to 1.1.x); this is the same code base with everything unlocked and the history
squashed.

Live readings

  • Power and clocks without sudo: system and CPU watts from the SMC, CPU and GPU clocks from IOReport residency, and IOReport energy rails (CPU, GPU, ANE, DRAM). Batched readings are held and marked ≈ with their age instead of dropping to zero.
  • Every Apple Silicon chip, M1 to M5, including Pro, Max and Ultra: per-cluster load for Efficiency, Performance and Super cores, with the clock each cluster ran at.
  • Heat and fans from the full SMC key list, mapped per chip into CPU and GPU zones; fanless Macs show no fans, desktops show no battery.
  • Battery: charge, state, health, cycles, time remaining, adapter, low-power mode and what is keeping the Mac awake.
  • Memory composition (app, wired, compressed, cached), swap and the kernel's free level.
  • A verdict (All normal, Busy: rustc using 9.1 cores, Hot: fans at 80%) with the evidence behind it.

Processes

  • Footprint memory, per-process energy, GPU, disk and wakeups; — instead of an invented zero when the kernel will not share a value.
  • Live filter, sort by any column, tree with subtree totals, group helpers by app, tags, and a details card with threads, open files and ports.
  • Safe signals (a reused pid is refused), a signal picker, renice, background QoS and copy over OSC 52.

Interface

  • Braille graphs on one shared, time-linear clock; z zooms time.
  • Two surfaces, Work and Glance, adapting from 80×24 up; five presets and a zen mode.
  • Themes built from your terminal's own palette, glass mode for translucent windows, ten built-in themes plus a theme pack, btop theme import, and 256-colour, 16-colour and NO_COLOR fallbacks.
  • Full mouse support, a full-screen settings page with search, and htop and btop key profiles.

Beyond the dashboard

  • --json / --json-stream (macmon-compatible field names), --diagnose, doctor and --demo.
  • Timeline (H) and siltop report: history on disk with energy by app, peak temperatures and time spent hot.
  • Alerts in the dashboard and from a background LaunchAgent (siltop agent install), with shell hooks.
  • siltop line for tmux, SketchyBar and Starship.
  • record / replay crash-tolerant session traces, a Prometheus endpoint (serve) and CSV export.
  • siltop bench: a sustained-performance test with a throttling report card.
  • siltop fleet: several Macs in one terminal over your own ssh.
  • Housekeeping: siltop theme list|import, siltop update (opt-in, verified self-update from GitHub releases), siltop feedback, siltop reset, siltop onboarding, siltop completions and siltop man.

Cost

  • About 1.3% of one core at a 1 s interval (btop: 2.5%, macmon: 1.4%, same machine); it only draws when something changed, and pausing stops sampling entirely. Method and numbers: docs/research/12-self-cost.md.
