Modify OS X's Accessibility Database from the Command Line

Apple has a utility in /usr/bin named tccutil, but it only supports one command, which is to reset the entire database. I wanted a command-line utility that would be able to add, remove, list, and take other actions.

macOS Sierra Support

Due to SIP, this utility will no longer work to modify the database (see #18)

How is tccutil.py Different?

  • tccutil.py can be installed without any additional software.

  • It can then be run just like any other command line tool. I also wanted the syntax to be easy to remember without having to look it up in the help menu.

  • There are other solutions out there, but there were some things I did not like about them:


  • Install using Homebrew, then run with tccutil:
      brew install tccutil

Depending how you have your $PATH variable setup, you can simply type tccutil (instead of the full path) and it will run this utility instead of Apple's.

  • Download from here and

    • copy manually to /usr/local/bin, then run with tccutil.py, or

    • run from any directory with python /path/to/tccutil.py.


This utility needs super-user priveleges for most operations. It is important that you either run this as root or use sudo, otherwise it won't work and you will end up with “permission denied” errors.

usage: tccutil.py [-h] [--list] [--insert INSERT] [-v] [-r REMOVE] [-e ENABLE]
                  [-d DISABLE] [--version]
