Repairing disk permissions is a troubleshooting activity commonly associated with Apple Computer's Mac OS X operating system.

The Darwin layer of OS X manages which users are able to access which files by maintaining a list of Unix permissions for each file. Over time this data can become corrupted or get changed as applications edit the permissions to allow necessary file access, then get terminated before reverting them. The result of this is that in extreme circumstances the operating system may not allow itself to access files that it needs. This has been reported by users to result in the wide variety of errors. Because of this, repairing permissions has become a standard troubleshooting first step to combat unexpected behaviour encountered on Mac OS X. Reparing permissions has been reported to fix problems with booting the system, misbehaving applications, Finder functions, malformed icons, problems with software installations and other problems besides. Although the necessity of carrying this process out as a maintenance activity has been called into question, some users claim that the process should be run on a weekly basis to prevent errors developing. The discussion is akin to that of "should OS X users use defragging software?"

The Apple Disk Utility application included in OS X provides the option to repair the Unix permissions on the hard drive that contains the operating system the computer is currently using. This will check and repair existing Apple software and system files.
