I tried to find some details about the daemon hidd but only found information about a Linux daemon where it is the human interface device daemon.

Is this the same function in macOS?

What is hidd responsible for?

hidd is indeed an abbreviation for Human Interface Device Daemon. It is responsible for the operation of any human input devices, such as your mouse, trackpad, drawing tablet or keyboard.

High CPU or memory utilisation?

If you are experiencing high CPU or memory utilization from hidd, you may want to restart your computer.

Can I kill the process?

No, if the hidd process is killed, it will restart immediately.

  • Can you elaborate on why it is restarted with high CPU as well? Or whether there is another solution than to restart your computer? (There has to be!) Jul 5, 2018 at 11:22
