Stats – macOS system monitor in your menu bar

Original Article ↗ Hacker News Discussion ↗

A free, open source macOS menu bar monitor called Stats is drawing attention as a close alternative to long‑standing paid tools like iStat Menus and MenuMeters. Users weigh its customization, broad sensor support, and low friction once configured against issues like occasional higher CPU use, Bluetooth quirks, unsigned‑app friction, and macOS’s cramped menu bar UX that often requires helper tools such as Ice or Hidden Bar. Many commenters argue that always‑visible CPU, memory, disk, and network graphs are invaluable for catching misbehaving apps and understanding system behavior, and they compare similar options across Windows, Linux, and KDE/GNOME environments.

Stats vs iStat Menus and other macOS monitors

  • Many see Stats as a very close (often called “clone-like”) alternative to iStat Menus: similar design, similar sensors, but free and open source.
  • Some long-time iStat Menus users switched to Stats citing better responsiveness, more SMC sensor support, and no cost.
  • Others still prefer iStat Menus for polish, configurability, compactness, weather integration, and overall UI quality; a few dislike iStat’s recent redesign.
  • Several users note that Stats is “good enough” and that iStat’s paid upgrades no longer feel necessary.

Installation, UI, and macOS menu bar quirks

  • A few users found onboarding confusing: after install only a battery widget appeared because other icons were hidden by limited menu bar space.
  • macOS’s behavior of silently hiding extra icons is widely criticized; users recommend tools like Bartender, Hidden Bar, or Ice to manage overflow.
  • One commenter shares defaults tweaks to shrink menu bar icon spacing, which helped some people surface hidden items.

Use cases and perceived value

  • Advocates consider continuous CPU/memory/network stats “essential” for:
    • Spotting stuck or misbehaving processes (e.g., background vim or runaway screensavers).
    • Understanding normal vs abnormal system behavior and app resource usage.
    • Debugging their own software in real time.
    • Seeing when transfers stall or unexplained network traffic appears.
  • Others realized they rarely looked at the graphs and removed such tools, using Activity Monitor’s live dock icon (or browser-specific performance pages) instead.
  • Some note these tools mattered more on constrained machines; on modern Macs they mainly help because fans and HDD noise no longer act as a natural warning signal.

Performance, bugs, and telemetry

  • Reports include:
    • Stats’ Bluetooth module causing high bluetoothd CPU usage (disabling doesn’t always help).
    • Higher CPU overhead than iStat Menus for some users.
    • Unsigned-update issues for some builds, requiring manual xattr fixes.
  • Stats checks for updates and includes optional telemetry; some see this as benign, others label any outbound traffic as “phoning home” and block it.

Alternatives and cross-platform context

  • On macOS, people mention MenuMeters, XRG, iPulse, and using Activity Monitor in the dock.
  • Windows suggestions: HWiNFO, Process Explorer, XMeters; question remains whether there’s a fully “programmable” tray-equivalent.
  • Linux/GNOME users point to extensions like system-monitor-next and Vitals; KDE Plasma is praised for flexible system monitor widgets.
