A USB device connected to the MacBook needs owner permission to perform write operations. If the user trying to make changes is not an admin account, the admin will need to assign the user account to the USB drive for the Read and Write privileges.

An admin account, however, has the option to ignore the ownership of all the files. If this option is enabled, the Mac OS treats all the data files in the same manner as they currently belong to the current user. It doesn't matter who is the actual owner. Here are the simple steps to perform this action.

  • Choose the disk, and then select File. Right-click on that and click on Get Info.
  • Find an option named Sharing & Permissions. To expand this section, click on the arrow next to it.
  • Sometimes there is a lock at the bottom left of it. If that is locked, click on unlock the preference pane.
  • Select the option to "ignore ownership on this volume."
