Thread starter halitri Start date Sep 12, We don't like Ads much either, but they do help cover the costs of running the site. The Get Info panel is the starting place for the setting of file and folder permissions. Notice the "everyone" user group designation. By default, every user account has full Read and Write permissions. Basically, this gives every user account the right to go into the Shared Folder and create files and folders. However, this would be contrary to the purpose of utilizing the Shared Folder.
A user who doesn't intend to share his files, should store them inside his own Home Folder. Refer to the article referenced above for more information on using the Home Folder. Incidentally, it's important to note that "everyone" includes other users on the network, if you have set your Sharing System Settings to allow this. In this case, the Shared Folder behaves like any other folder with respect to how files can be moved and copied.
Because, by default, other users are given Read Only permission for all but their own files and folders, those users are able to open and read files, and to open folders, that belong to other user accounts. However, "Read Only" means that there can be no modifications or deletions except to ones own files and folders. From this point on, the copy will be owned by this user. If, within the Shared Folder, one user attempts to modify or delete a file or folder belonging to another user, OS X will display a warning and a request authentication.
Returning to my teaching scenario. To make things easier for myself, and because I am the only person who uses this MacBook Pro, there is a very practical change I make to the permissions settings.
Let me explain. As already mentioned, on my Mac I have assigned a distinct user account for each of my courses. You will find out when and how to use each method to share files and documents between users of a same Mac. Each macOS installation comes with a Shared folder , and each user of that Mac has access to it.
The Shared folder is probably the easiest and quickest way to share files and documents between users, understanding that every user will be able to access them. If other users have already placed files in there, you will see those files. You will also be able to paste or drag files in that Shared folder for others to see. The Public folder of each user with an account on your Mac is shared automatically.
To prevent a folder from being shared, select it in the Shared Folders list and click the Remove button. Control-click the name of the folder, choose Advanced Options, select desired options, then click OK.
