The MAC OS’s built-in disk encryption feature is known as FileVault. It’s designed to encrypt your Mac’s hard drive and all the files located on the drive using 128-bit AES encryption with a 256-bit key. This prevents unauthorized access to the information on your startup disk.
It can be accessed by clicking on the Apple menu > System Preferences, then clicking on Security & Privacy > then the FileVault tab.
The FileVault can be turned off as well, by default at enterprise level the FileVault is always switched on. It is also advised to users using the MAC not to switch it off. Individual and enterprise users are concerned with security and privacy of data. If the mac is stolen the FileVault will prevent it from gaining unauthorized access.
