You can use the Repair Disk Permissions feature to make sure system file and folders are set to the proper ownership and access as specified by its installer in /Library/Receipts/.
Notes:

  • Repairing Disk Permissions does not include user-level files in /Users.
  • You should Verify/Repair Disk before doing a Verify/Repair Permissions.

For OS X 10.11 El Capitan:

  1. Launch Terminal (located in Applications > Utilities)

  2. To verify permissions, enter the following command:

    sudo /usr/libexec/repair_packages --verify --standard-pkgs / sudo /usr/libexec/repair_packages --verify --standard-pkgs /

  3. To repair permissions, enter the following command:

    sudo /usr/libexec/repair_packages --repair --standard-pkgs /

For OS X 10.10 Yosemite and earlier:


Note: Always use Disk Utility from the same version operation system.

1. Launch Disk Utility (located in Applications > Utilities)


2. Choose your hard drive from the left side column. Then click Repair Disk Permissions. This will attempt to repair any errors found.
