What is tccd and why is this process running on my Mac?

When looking into the Activity indicator Have you found the tccd process on your Apple Mac and now want to know what it's all about? No problem, you came out on the right page! Here you will find all the information about what tasks and permissions the tccd process has in the macOS operating system. At the beginning I can also reassure you: this is a background process not um malicious software.

The tccd process on the Mac: managing app access to the system and memory

The tccd background process on the Apple Mac is a so-called daemon, i.e. an independently acting process that is intended to simplify the use of the operating system for users. More about it here: What is a daemon? The full name of the process is included Transparency, Consent and Cuntroll Daemon. It regulates full access to the hard drive, use of the location service, sharing of contacts, microphone and camera access, use of accessibility features and more by individual apps.

The tccd process does not activate and control the individual content and elements directly, but simply keeps a record of which app you have given or withdrawn access to the individual areas. He is therefore responsible for ensuring that certain programs are granted access while others are blocked. You can change the permissions both in the Mac's settings and in individual app settings, which tccd then remembers in order to assign them again for later use and to respect your privacy settings.

Mac settings for app access and usage permissions

Click on the Apple logo in the menu bar at the top left and then click on the menu System settings ..., then you will be taken to the settings of your Apple computer. There are now some areas where you can assign permissions for individual apps. These include the following:

  • General
  • Messages
  • Accessibility
  • Data Protection & Privacy
  • ...

Conclusion: An important process for safe Mac use

As a human-machine interface, the tccd daemon ensures that the permissions and blocks you assign are enforced for individual apps and services. If one app should be allowed to access your camera and microphone, but another should be excluded from this option, then the tccd process regulates this. The same applies to access to contacts, your own contact information, the hard drive or individual directories, and so on. If the process goes crazy and uses too much CPU or RAM, restarting the Mac can help (switch it off once, wait a moment, then switch it on again).
