![]() Those two checks should cover almost all the problems which you’re likely to come across in practice, but PermissionScanner can do a great deal more. In my case, the two files out of over 32,000 which were scanned are buried in some developer folders, so I presume that those permissions are correct. Look carefully at their paths and you should be able to work out whether this is fine, or a problem. This is more likely to discover a few files which aren’t writable. You can expand that to cover all the individual Preferences folders in the Containers and Group Containers folders, and anywhere else in ~/Library, by changing the popup menu to Home All Prefs, then running a check that all are writable. All you should need to do is select the offending file, Command-I to Get Info, then set yourself, as the file’s owner, to have read and write access, and check that the file isn’t locked. If this reveals that a Property List or other file in ~/Library/Preferences can’t be written to, that’s easy to correct in the Finder once you’ve made ~/Library visible (Command-Shift-.), or you can copy and paste the path directly into Terminal to correct it there if you prefer. This should normally return no files if one of your preferences files can’t be written to, it’s going to cause a problem somewhere. This reports all those files within ~/Library/Preferences which aren’t writable by you as a user. The most basic check to run is the default when you open a new window in the app: that Home Preferences are writable. If you don’t do that, expect to see lots of errors. Permissions reset download full#If you’re running Mojave or Catalina, the first thing you’ll need to do is add PermissionScanner to the Full Disk Access list in the Privacy pane. PermissionScanner looks at every folder and file within a specified standard folder on your Mac, and checks whether you, the current user, can read that file or can write to it (your option). It may appear at this stage that trying to do anything in this sort of labyrinth is going to be futile. Eventually you’ll find that most of those links lead back to original folders and files still in locations like ~/Library/Preferences. Some of these are just links to the originals, and others contain many linked folders. To see this, select one of the folders inside Containers, then select the Data folder inside that, and you’ll see what appear to be duplicates of other folders like Documents and Library. ![]() Those two folders contain many links to other folders and files. ![]() Unfortunately this has become more complicated with the introduction of two other folders, Containers and Group Containers, which are now used widely. Permissions reset download software#There are several important folders inside ~/Library which are most likely to result in problems, but the one most often involved is Preferences, where apps and other software maintain Property List files containing settings. So the first aim of this approach to solving these problems is to concentrate on ~/Library rather than the whole Home folder. The great majority of the problems caused by ‘incorrect’ permissions settings in your Home folder occur not in folders like Documents, but in that hidden Library folder. The major exception to this is its Library folder, which is normally hidden. You decide which files go into Documents, and whether you also use a custom folder for other documents. Most of the folders inside your Home folder are under your direct control.
