Dec 01, 2015 Fortunately, Mac users have lot of possible encryption options nowadays (built in Mac OS tools and 3rd party encryption apps as well). Built Mac OS Disk Utility tool allows to protect your private files and create encrypted folder disk image. Nov 30, 2018 FileVault full-disk encryption (FileVault 2) uses XTS-AES-128 encryption with a 256-bit key to help prevent unauthorized access to the information on your startup disk. Jan 24, 2018 To encrypt a drive, simply open the Finder and connect the drive to your Mac. Ctrl+click or right-click the drive in the Finder sidebar and select the Encrypt option. The disk will be encrypted once you enter your password of choice—be sure to use a secure one!
Mac computers that have the Apple T2 Security Chip integrate security into both software and hardware to provide encrypted-storage capabilities. Data on the built-in, solid-state drive (SSD) is encrypted using a hardware-accelerated AES engine built into the T2 chip. This encryption is performed with 256-bit keys tied to a unique identifier within the T2 chip.
The advanced encryption technology integrated into the T2 chip provides line-speed encryption, but it also means that if the portion of the T2 chip containing your encryption keys becomes damaged, you might need to restore the content of your drive from a backup. This content includes system files, apps, accounts, preferences, music, photos, movies, and documents.
Always back up your content to a secure external drive or other secure backup location so that you can restore it, if necessary. You should also turn on FileVault for additional security, because without FileVault enabled, your encrypted SSDs automatically mount and decrypt when connected to your Mac.

Set up Time Machine or another backup method to regularly back up your Mac to a secure external source.
Files that you store in iCloud Drive, as well as photos and videos that you store in iCloud Photo Library, are automatically uploaded to iCloud. When you use iCloud Photo Library, full-resolution photos and videos are stored on your Mac by default and included in a Time Machine backup. If you choose to optimize iCloud Photo Library on your Mac, the full-resolution originals are not included in a Time Machine backup.
Turn on FileVault
Though the SSD in computers that have the Apple T2 Security Chip is encrypted, you should turn on FileVault so that your Mac requires a password to decrypt your data.
