Features

Not just what's running. Why your Mac is slow.

Four things iKnowMyMac does that a process list can't, built on a complete set of everyday monitoring. Every feature is included in one license.

The four differences

Answers, not dashboards

Core

Everything you'd expect from a system monitor

The foundation the four differences are built on. All included.

  • Apps, not processes

    About 1,100 processes become about 50 app rows on our test Mac. Every Chrome and Electron helper sits under its app.

  • Overview

    CPU, memory, GPU, disk, network and battery cards, each with its current value, one key detail and a sparkline.

  • Per-metric tabs

    Apps sorted by the metric you're looking at, with expandable rows that show each process.

  • Menu bar extra

    Four display modes (icon, single figure, sparkline, stacked figures) and a popover with the busiest apps.

  • 30-day history

    10-second resolution for a day, 1 minute for a week, 5 minutes for a month.

  • Misbehaviour alerts

    Sustained CPU, memory growth, heavy disk writes and heavy network, plus your own alert rules and thermal throttling alerts.

  • Temperatures and fans

    CPU and GPU temperatures and fan speeds, validated on M1 Pro. Other chips show the thermal state.

  • Accessory batteries

    Battery levels for Bluetooth keyboards, mice and trackpads.

  • Quit and force quit

    From any app or process row. Always confirms and says how many processes will close.

  • Share card

    A share card image of your Mac's current state, and “Copy dashboard” for the whole window.

  • Read-only helper

    Optional. It reads system data the app can't see on its own, and it can't run commands or change anything.

  • Weekly digest

    A weekly summary of what used your Mac, generated on your Mac.

Honest limits

What iKnowMyMac doesn't do

So you can decide before you buy. If you need one of these, one of the apps we compare against may suit you better.

  • Per-app network or per-app GPU numbers (network and GPU are system totals)
  • Intel Macs (Apple silicon only) or macOS versions before 15 Sequoia
  • Widgets, Shortcuts, a command-line tool or a Raycast extension (not yet)
  • Per-app volume control
  • Cleaning, “optimizing” or freeing RAM (by design)
  • A free trial (instead: a 14-day refund)
