How to Make Files Undetectable on a Mac

Hide your personal files away in an encrypted disk image.

Mac OS X includes a disk encryption feature that allows you to password protect all or part of your computer's hard drive. If you have files that you don't want people to be able to find, you can encrypt a portion of your hard drive and place the files in that encrypted segment. The list of files stored on an encrypted disk can not be viewed without your password. The files also don't appear in search result if someone searches your hard .
