I would like to set a password on a folder so shared users can not access it, how do I do that?

    Click here and follow the instructions. Don't add the encrypted image's password to the keychain.

    I created encrypted partition but now I can not figure out how to move new documents into it.  It seems like a static drive?

    Almost every discussion I see on this topic suggests creating an encrypted or password-protected r/w disk image of the folder you want to protect, but that's not really password-protecting a folder; it's duplicating it onto an image.


    You should be able to make any folder inaccessible by getting info on it (Cmd-I) as administrator, then selecting Read Only under Ownership & Permissions. However, MAC OS screws this up and sometimes when you do that, you can't undo it, i.e. you lose everything that was in that folder.


    Has anyone else experienced this..? It seems like typical sick Mac OS crap to me. Why shouldn't you just be able to change the permission back to Read and Write????????

    Without specific directions, I can’t replicate what you are seeing.

    The whole concept is not secure, though. And, it doesn’t prevent anyone from accessing the contents of the folder, except perhaps, you.

    I realize this is quite old, but the thread was resurrected from obscurity.

    If you used a Sparse disk image or a Read/Write disk image format, you should be able to add and delete files to the mounted disk?

    To mount the Image, double-click it and enter the password. It shows up as a hard drive. Use it like any other. Like a hard drive, it has limited space based on what you set for its size when you created it.

    How do I add more space after I have created it? Or better yet, how can I revert back to a normal "unprotected folder" I don't want to have it password protected anymore, it's turning out to be a pain. (unless adding more space works)

    Remove the files/data from the disk image and then delete it.

    Thank you Eric. I guess I was trying to over complicate things. Copying everything into a new folder worked.

    I have created an encrypted dmg file, but how do I add files to it? When I click on it nothing happens ... should a password window not appear?

  • Barney-15E Level 8 (46,274 points)

    When you create it, if you entered the password, then let it store it in keychain, it won't ask for a password. You will have to remove it from your keychain using Keychain Access.

    It should mount as a disk drive when you double-click it.

    Thanks, got it.
