The first release of Caliper — a native macOS system monitor that lives in the
menu bar, keeps a real history of what the machine has been doing, and is built
not to become the load it measures.

In this build

  • Menu bar — CPU, memory, network, disk and temperature, each drawn at a
    fixed width so nothing shoves its neighbours around. Every module is
    configured on its own: the picture is its live graph, the symbol that names
    it, or nothing, and the value switches on and off beside it. The modules can
    also share a single item, in an order you set by dragging.
  • Panels — one behind each module. CPU with its performance and efficiency
    clusters, per-core bars and the heaviest processes; memory pressure and
    composition; disk throughput, free space and drive health; network rates with
    the interface and address behind them; every sensor and fan the machine will
    report.
  • History — recorded locally to SQLite from the moment the app starts,
    rolled up 10 s → 1 min → 10 min → 1 h, and charted over an hour, a day, a
    week, a month or a year. Nothing leaves the Mac.
  • Cost — under 1 % of one core and under 50 MB of physical footprint in
    menu-bar-only use, measured by a harness rather than hoped for.
  • Updates — Caliper now checks for its own, quietly: a scheduled check that
    finds something marks the menu bar rather than interrupting you, and every
    update is verified against the developer signature before it is applied.

Requirements

macOS 15 or later, Apple Silicon. Sensors are read on a best-effort basis: what
a particular Mac will not report is hidden rather than guessed at.

Installing

Open the disk image and drag Caliper to Applications. The build is signed with
a Developer ID and notarized by Apple, so it opens without a warning.
