What is parsecd on Mac?

parsecd supports search suggestions in Spotlight, Safari, Siri and Look Up. It connects when you type in those places.

Process: parsecdApplies to: All current macOS versions. Seen on macOS 27.2.Checked: 29 October 2026

Where you see it

  • parsecd is in the list in Activity Monitor › Network, in nettop or in Kilobat.
  • A firewall or network monitor asks if parsecd can connect.
  • Traffic appears when you type in Spotlight or in the Safari address field.

What it is

The man page says that parsecd “manages access and data for Siri Suggestions, Spotlight Suggestions, Safari Suggestions, Lookup, #images, and Apple News article search”.

Why it uses the network

  • Suggestions while you type. Suggestions from the web need a request to a server.
  • Look Up and images. Look Up and #images get their content from the internet.

Is it normal?

Yes. Small requests while you search are usual.

See how much it uses

Reduce or pause it safely

  1. Choose Apple menu > System Settings > Spotlight. Turn off the search results and suggestions that you do not use.

  2. In the same place, turn off Help Apple Improve Search if you do not want to share search queries.

  3. In Safari, choose Safari > Settings > Search. Turn off the suggestions that you do not use.

  4. Do not quit parsecd in Activity Monitor. It is part of macOS, and other features depend on it.
