How can I secure a folder or file rather than the whole mac
I would like to secure just a folder and its contents with a password, rather then the whole machine.
You could use an encryption app. Unfortunately you have only give skimpy details of your machine in your profile so I can't be sure if this lead answers your question. Please update your profile to tell us which machine, OS and how much RAM you have available.
