First, boot into Single User mode by restarting and holding the Command-S keys. This will drop you to the command prompt where you will have full "root" access to the system. From here, run the following commands to set the desired account's files and folders to be accessible change "username" in the command to the short name of the specified account :.

Explanation : ACLs are "Access Control Lists", which are a more elaborate and thorough way of assigning permissions than the older POSIX permissions and may be appended to files and folders sometimes inadvertently by numerous programs and system commands. There are many configuration details to ACLs that are not directly editable in OS X, such as assigning unique permissions to more than one specific user without using groups, or even having multiple entries of different permissions for the same user. This can cause confusion and can prevent access to files even though they appear with proper permissions in the Finder.

Because ACLs are not required for setting up the basic OS X account permissions and because they can actually prevent access to the account if set up incorrectly, you can remove them. The group, denoted by ":staff" is set to "staff" here because this allows permissions to be set for administrators in the system admins are members of the "staff" group ; however, in this procedure setting the group will not affect much since we are going to be setting the group's permissions to "no access" in the next step.

Explanation : This command is the "meat" of the procedure, and is what will actually change permissions. Once we've set up all files so permissions can be uniquely set for the specific account holder the "owner" , this command will grant access to all files in the directory only to that owner, and set the files' group associations the "group" and "everyone" to "no access". The "" in the command is a bitwise designation of permissions to the file's "owner" first digit, or "6" in this case , to the "group" second digit, or "0" in this case , and to "everyone" the third digit.

If there is order in the universe, everything just works. However, if these permissions get messed up — maybe a third-party app installer sets incorrect permissions on the files it installs or messes up the whole application folder — then weird things will occur. Have you seen a question mark instead of the app icon in the dock? Have you had troubles connecting to the internet?

Or is Spotlight failing to find a file? Such problems are caused by incorrect permissions.


Also, it is worth noting that your home folder contains many files and folders that third-party apps have permissions to either read or write to. By modifying permissions with Get Info or another method, you might experience issues such as:.

If you encounter any of the issues mentioned, then you definitely need to repair permissions. We recommend running a maintenance script regularly — at least once a month.

With the introduction of System Integrity Protection in OS X El Capitan, however, Apple removed the repair permissions feature from Disk Utility, claiming that the system files are now protected from intentional and inadvertent change and therefore eliminating the need for this tool. You will boot into the Repair Utilities screen.
