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/.
To verify permissions, enter the following command:
sudo /usr/libexec/repair_packages --verify --standard-pkgs / sudo /usr/libexec/repair_packages --verify --standard-pkgs /
To repair permissions, enter the following command:
sudo /usr/libexec/repair_packages --repair --standard-pkgs /
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.
