All you need is MacFort, a simple app that displays all the installed applications on your Mac. With a couple of clicks you can lock and protect their files with a password.
MacFort protects your iPhoto albums, Mail on your Mac, Contacts, Safari, Chrome, or Firefox browsing histories, and even files and folders in your Documents folder.
Take a look at how easy this is to use. Upon startup, MacFort scans your Mac for apps (or, you can add an app manually).
How MacFort works is rather simple. For example, once protected, iPhoto requires a password to open and use the iPhoto library stored on your Mac (or, stored on an external disk drive connected to your Mac).
MacFort uses standard military-grade AES encryption to encrypt the files in a vault.
You can also lock up individual folders or files. If your Mac or disk drive is stolen the thief won’t be able to view the files without the password. It just won’t happen.
MacFort works similar to the built-in FileVault on your Mac except you get individual file or folder control, and can pick and choose which apps and their data are to be secured.
This is nicely done and easy to setup and use, but is aimed more for Mac users who have sensitive data which should not be allowed to fall into the wrong hands.
