How to remove "Reminders.app" from Mac OS?

How can I delete the folder "Reminders.app" from Mac OS when the current permissions assigned to the folder is currently Read Only for everyone and Read & Write for system?

I've tried sudo / terminal, attempted to change permissions via the finder and all attempts to dislodge the folder result in access denied. Is rebooting into a special unprotected mode required?


Solution 1:

All the default apps are protected by System Integrity Protection.

To disable System Integrity Protection, you can do the following:

  1. Boot into the Recovery HD by restarting whilst holding ⌘R.
  2. Open Terminal (from the Utilities menu).
  3. Run the following command in Terminal:

    csrutil disable
    
  4. Restart.

Source: Disable OS X El Capitan Rootless and permit write actions to System Integrity Protection locations

You can re-enable it once you've deleted the app.
