    Are you trying to securely encript the file/folder ?


    If you are you could turn on File vault in system preferences - this will encript your entire home folder on the fly


    Or if you want you could create an encripted disc image and store files on that


    What is it you are trying to do ?

    if you just have a personal file you dont want other users to read

    you should make more users 1 for each user of the computer like

    one called


    one called NK008

    one called NK009


    the 2 other users will not have access to NK007's files so can't open them with or without password

    You can password lock files within some programs. For example, Pages and Numbers allow this. To access that feature for a file, with the file open click the Inpector item in the toolbar, then click the leftmost item in the Inspector window's toolbar (Document inspector). The option to password lock the file is at the bottom of that screen.

    Create a password protected encrypted sparse bundle and stick it in there. Choosing a sparse bundle will allow that folder to grow as you use it. I keep all my sensitive stuff, taxes etc. in there. Be sure not to have Keychain remember it. And don't forget the password. If you do, it will be gone forever.


    It's really not complicated.

    You've got the file safe in your account and you want your wife to also have the same document available in her user account right? Email it to her.

    Easy way is to use disk utility to create a disk image. It will default to 100 mb but make it what you like.

    Select encryption and a name etc.

    Put in password.

    Put the image it creates on the desktop or wherever and put files into it.

    When done with it, throw it in trash to close the image. (it will still be on desktop.)

    When you select it, it will ask for password.

    (mess around a bit to be sure everything works)
