System tools

See what your computer is doing, and manage displays and disk space.

  • Status

    CPU, GPU, memory, disk, chip temperature, battery and network on one screen.

  • Recent graphs and top apps

    Small graphs of the last few minutes, and the five apps using the most CPU and memory.

  • Menu bar readout

    Show CPU, memory, GPU or temperature next to the menu bar icon.

  • Alerts

    Notifies you at CPU or memory 90%+ for 2 minutes, chip 100 °C+ for 2 minutes, under 10 GB free, or battery 15% or less. The same alert at most every 30 minutes.

  • Brightness

    External monitors over DDC/CI, the built-in screen through its backlight — or all of them with one slider.

  • Display off

    Turns an external monitor's output off by disconnecting it in macOS. USB and charging keep working.

  • Cleanup

    Preview and clean caches and leftovers with Mole, one task at a time, with your user rights.
