What is coreaudiod?

Publisher: Apple Inc.Typical location: /usr/sbin/coreaudiod

coreaudiod is a legitimate macOS system process from Apple that handles audio on your Mac. It is normally safe and expected to run in the background, and it helps your Mac play sound, manage microphones, and keep audio devices working.

What it does

coreaudiod is the Core Audio daemon, part of macOS’s built-in audio system. It manages sound input and output, audio routing, volume changes, microphones, and communication between apps and audio hardware. If you plug in headphones, switch audio devices, use a microphone, or play a video, coreaudiod is usually involved.

Is it safe?

Yes, the real coreaudiod process is safe and should be left alone. However, malware can sometimes use the same name to look legitimate. To tell the difference, check the process location and signature: the real Apple process should be in /usr/sbin/coreaudiod and signed by Apple Inc.. If it is running from a different folder, has no valid Apple signature, or looks unusual, treat it as suspicious.

Why it causes high CPU or disk usage

  • 1A stuck audio app or browser tab
  • 2Problems with a USB, Bluetooth, or headphone audio device
  • 3A corrupted audio service state after sleep or device changes
  • 4macOS bugs or outdated system software
  • 5A misbehaving app repeatedly accessing the microphone or sound output

How to check if it's legitimate

  1. Open Activity Monitor and select coreaudiod.
  2. Check the Path or Open Files and Ports details if available. The legitimate process should point to /usr/sbin/coreaudiod.
  3. Verify that it is signed by Apple Inc. if your Mac shows code-signing or signature details.
  4. If the path is different, the signature is missing, or the file is running from a user folder or temporary location, be cautious.
  5. If it looks normal but is using too much CPU, try quitting the app using audio, unplugging external audio devices, and restarting your Mac.

How to remove it

You should not remove the real coreaudiod process. It is a core macOS audio service, and ending or deleting it can break sound, microphones, and apps that rely on audio. If it is using too much CPU or disk activity, restart your Mac, disconnect external audio devices, close audio-heavy apps, and install the latest macOS updates. If the process is running from an unexpected location or appears unsigned, run a malware scan and contact support for help before taking further action.
