How to Lock a File on a Macby Bennett Gavrish
If more than one person uses your Mac computer, consider locking private files that you do not want other users to access. When another user attempts to open a locked file, the operating system will issue a warning stating that the user does not have sufficient privileges to read the file. In addition, other users will not be able to delete your locked files.
Open a new Finder window by clicking on the icon in the Dock.
Navigate to the location of the file that you want to lock.
Right-click on the file's icon and choose "Get Info."
Check the box next to "Locked" in the file's information window.
Close the information window to save the settings. The selected file is now locked and will not be able to be opened by other users.
