OS X Mavericks: Set permissions

Set permissions

Permission settings determine who can view and alter disks, folders, and files.

Assign permissions to users and groups

  1. Select a disk, folder, or file, then choose File > Get Info.
  2. If the information in Sharing & Permissions isn’t visible, click the disclosure triangle.
  3. Select a user or group from the Name column, then choose one of the following from the pop-up menu in the Privileges column. If necessary, click the lock icon and enter an administrator’s name and password.
    Option Description
    Read & Write: Allows a user to open the item and change it.
    Read Only: Allows a user to open the item, but not change its contents.
    Write Only: Makes a folder into a drop box. Users can copy items to the drop box, but can’t open it. Only the owner of the drop box can open it.
    No Access: Blocks all access to the item.

Apply permissions to all items in a folder or a disk

  1. Select a folder or a disk, then choose File > Get Info.
  2. Click the lock icon to unlock it, then enter an administrator’s name and password.
  3. Choose "Apply to enclosed items" from the Action pop-up menu (looks like a gear).

Change an item’s owner

  1. Select the item, then choose File > Get Info.
  2. Click the lock icon to unlock it, then provide an administrator’s name and password.
  3. If the new owner’s name isn’t listed in the Name column in the Sharing & Permissions section, click Add (+) to add the new owner.
  4. Select the new owner in the Name column, then choose “Make __ the owner” from the Action pop-up menu (looks like a gear).

Add or remove a user or group in the Name column

  1. Select an item, then choose File > Get Info.
  2. If you don’t own the item, click the lock icon to unlock it, then provide an administrator’s name and password.
  3. In the Sharing & Permissions section, do one of the following:
    • To add a user or group, click Add (+) below the table, select a user or group, then click Select.

    • To remove a user or group, select the user or group, then click Delete (-) below the table.

Undo changes

You can undo any changes made in the Sharing & Permissions section of an Info window since opening it, except applying permissions to all the items in a folder or disk.

  1. Make sure the Info window remains open after making your changes.
  2. Choose “Revert changes” from the Action pop-up menu (looks like a gear).

Set permissions of shared folders

  1. In the Finder, select the shared folder, then choose File > Get Info.
  2. Use the Sharing & Permissions section to assign permissions to users and groups.

You can also select an unshared folder. Choose File > Get Info, then make the folder shared by selecting “Shared folder” in the General section of the Info window.
