Have you ever wanted to protect one of your folders from another user or only for security purposes? Well, it’s possible. Using the integrated encryption functionality of Mac OS X, you can protect any file or folder with a 128-bit AES encryption or a more secure 256-bit AES encryption but 128-bit encryption is recommended.

How to proceed?

1. Open Disk Utility (can be found by searching in spotlight or in Applications folder -> Utilities)
2. Go to file -> New -> Disk image from Folder -> Choose a folder to protect
3. Change the encryption to 128-bit AES and click Save (It will create a .DMG file)
4. Then it will ask for a password, you can either choose one yourself or a more secure one from Password Assistant if you click on the key image behind the “Password:” field at the right.
5. Click OK. You can now double-click your encrypted .dmg file and Voila!

You have successfuly protected a folder using a high end encryption system. This is the best and more secure way to protect a file or folder on your Mac.

MAKE SURE TO REMEMBER THE PASSWORD CHOSEN, A LOST PASSWORD CANNOT BE RETRIEVED.
