    @Mike
    You forgot to cross off “add to keychain” when you set the password for the disk image.
    That´s why it opens without you having to type a password.

    this creates two separate icons, one is a disk image, like you said, and the other has the .dmg extension, and appears like a document. i can drop things in the disk image, but not in the .dmg, and the disk image can be opened without a password.

    maybe i’m missing something

    This is useful for some situations, but I’m looking to password protect a folder that I can then add things to or modify the contents of the folder. Using the disk image method I’d have to make a new disk image every single time I modify the contents.

    Good idea but should you not uncheck the “Remember password in my keychain” box because that can be read.
