Once those had been fixed, Apple considered there should be no further need for such repairs.Īlthough Home folder permission problems in more recent versions of macOS are undoubtedly far less frequent, they do still occur. At that time, I suspected that these pernicious problems had arisen because of bugs in the background service that manages preferences, cfprefsd. By June 2020, Apple had removed that support note too, silently erasing all trace of these procedures. In March 2020, Apple changed the procedure again, to running a new tool named repairHomePermissions in Recovery mode, then reinstalling macOS. I proposed alternatives in another chart. As I noted at the time, that seemed rather drastic.
Nearly three years ago, Apple changed its support note to recommend reinstallation of macOS rather than use of the diskutil command. Repairing permissions in this way became so popular, and effective, that I introduced my own tools to help, and diagrammed it.

If you want to read a full account of the original procedure, this article explains all. In Terminal used to elicit usage information.
Repairing these required the diskutil command tool, and although it has never been mentioned in its man page, typing These largely result from broken permissions and related problems in ~/Library/Preferences. problems with Photos or iPhoto libraries, including inability to import into the library, or forgetting the library each time the app is opened.Safari or SafariDAVClient use large amounts of resources (memory).alerts warning that the startup disk has no more space available for app memory.Preview, TextEdit, and App Store apps (which are sandboxed) may crash when opened.when trying to save, you are told that the file is locked, or that you don’t have permission.you are asked to authenticate when trying to move or alter some folders in your Home folder.changes made to the Dock do not ‘stick’.changes to preference settings, particularly those for System Preferences, do not ‘stick’.Problems with Home folder permissions first became prominent in Sierra, when Apple quietly posted a support note (long since removed without being archived) recommending a new procedure to fix a long list of problems, including:

This article is about how to deal with that, and how Apple’s advice has changed. When they do, they can have protean effects, of which the most visible is being prompted to authenticate when trying to move or alter folders and files you should own and control. That was mostly fixed with the introduction of System Integrity Protection (SIP), and finished for good with the SSV.īut permissions can still go wrong in sensitive parts of the Data volume, most importantly inside your Home folder. Long before the introduction of the signed and sealed System volume (SSV), permissions could go astray in the System, causing havoc. Permissions are one of the fundamental controls in macOS, to determine what you can see and do with files and folders.
