macOS is Unix at its heart, and Unix thrives on “ownership” and “permissions.” These are attributes attached to every file and folder that describe which users and groups have the right to perform what actions on them: read or view, modify, delete, or, in the case of folders, also see the contents, remove items, and add items.
Get Info lets you change permissions recursively for folders (every nested item) or for groups of items.
The Finder mediates access to permission (it calls them Privileges in some places), and manages a number of Apple-specific attributes we rarely have to know about. But sometimes things go out of joint, and the Finder can help set them right. One reader noted after a number of transitions, they had a mass of files marked as “Read only.” Even though their user account “owned” these files, it’s still a one-at-a-time override situation for them to interact with those files, and a constant hassle.
The solution is very straightforward, fortunately.
For files organized into a folder or set of nested folders:
For files and folders that are scattered: You can change their permissions as a group, but only by selecting either files or folders in a pass. If you have both files and folders, you have to select first all the files and then all folders. Follow these steps:
If the permission changes require access to folders outside your user account, you will be prompted for an administrator password. Otherwise, they are immediately applied.
