    You can protect files on your Mac from prying eyes by storing them in an encrypted disk image. To access the files, you simply need to mount the disk image and supply a password, and to lock it up again, eject the disk image.

    1. Open up Disk Utility. (/Applications/Utilities/Disk Utility)

    2. Navigate to File > New > Blank Disk Image.

    3. Choose a name and save location. Be sure to enable encryption. (128-bit is recommended, so we will use that.) Also, make sure you can read/write the image.

    4. Click "Create". You will then be prompted to supply a password. I would choose a password other than your account password.

    Congratulations! You have created an encrypted disk image.
