Mac X 10.11 El Captain disk utility does not come with repair disk permissions option. This is frustrating to most Mac users since repairing disk permissions used to be typical maintenance we perform on our Macs. According to Apple, file system permissions are protected in the latest version of OS X El Captain. While this may be true, it is still possible some application or action you performed changed permissions – so why not still check and repair?

1. Open Terminal (Applications -> Utilities -> Terminal)
2. Type the following command to immediately repair disk permissions on your home volume:
sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /
3. Disk Utility will do its thing and eventually finish pictured below.
