If the setup is this brittle you’d think Apple could redesign how the user-accessible pieces are maintained such that they are no longer at risk of such problems (which is essentially what iOS does, with all the compromises and limitations that come with it). They don’t then explain *which* of the files or folders are vulnerable to this behavior. If you use Get Info or other methods to change those permissions, you could experience issues such as these…” “Your home folder contains many files and folders that apps on your Mac have permission to read or modify. As soon as I have any further news on this, I will update this article. This doesn’t appear to have propagated out to some localised pages yet, which may still show the previous version.Īpple has removed its article, and currently doesn’t appear to cover this problem at all. To see the revised procedure, you may need to read Apple’s US version of this note here. We may all be locked down at present, but that doesn’t mean we want to spend all day tinkering with our Macs to sort them out. Apple, you need to come up with something a tad more practical. If macOS has reached the stage where you have to do that to fix permissions on a few files, then we’re all in deep trouble. If you think that is an incredibly long-winded procedure to correct the permissions on a few property lists in ~/Library/Preferences, you may instead prefer to use my free utility PermissionScanner and the procedure which I previously described, before attempting such extreme measures. Use Migration Assistant to restore files from your previous account.In the subsequent setup, create a new and different primary admin user account with a different name.Start up in Recovery mode again and erase your startup disk as detailed here.Ensure you have a full backup of your Mac.If that procedure doesn’t resolve the problems, Apple recommends: Once that is complete, restart in normal mode.In the main Recovery mode window, select Reinstall macOS, and click on Continue to reinstall macOS in its entirety.Once that has completed, click on the Exit button.If that isn’t an admin account, Apple doesn’t explain what you should do. Select the correct user account from those offered, and enter the admin password for that account. That should launch the Repair Home app.There type repairHomePermissions and press Return.Once in Recovery mode, open Terminal from the Utilities menu.Start up in Recovery mode by holding Command-R.The new procedure consists of the following sequence: Apple doesn’t state which versions of macOS this applies to, but it should be for Catalina 10.15.4 at least. This is a major change: the whole procedure is now different, and has to be performed in Recovery mode. They should be forced to walk the plank.In the last few days, Apple has again changed its recommended procedure for resetting or repairing permissions on your Home folder. Sometimes a developer will pull a fast one, and use an app bundle as an installer. mpkg, double-click right there in the disk image window. An installer should be filename.pkg (installer package) or filename.mpkg (multi-package – 2 or more packages that typically run in series). In Windows, they both look the same (filename.exe), but in OS X, an app SHOULD be a ready to use bundle. One comment mentions distinguishing an installer from an app. It is possible for a Zip to be programmed to self-expand and the contents can be programmed to self-install. There is a level of verification that does not occur with a Zip. There is also some increased security process for DMG. These folks who put an arrow image in their DMG window should add the words "DRAG TO APPLICATIONS" to the arrow, because I promise you, a surprising percentage of new-to-Mac folks miss the idea, as one commenter here said. DMG works similar to connecting a thumb drive – no startup volume space is needed, until you drag the needed files to the internal drive. Zip needs drive space to expand, since it actually makes a new directory to duplicate in larger format what is in the archive.
