Disk utility is a great option to encrypt if the drive is empty or not yet partitioned, then transfer the files when done. Another way is to create encrypted disk images, which add a security layer.

Tip 3: Encrypt System Data

You can password protect file Mac by encrypting system data, which means securing the Mac itself. This approach is great at preventing the unauthorized editing or access to data. There are various ways to secure your Mac like encrypting the startup drive contents using FileVault. Secure your user account using a strong password that is hard to guess to prevent bypassing FileVault protection.

You can also activate screensaver password to prevent access when Mac is on and after logging in. Setting a firmware password also protects files from being accessed through booting Mac with another startup drive.

Tip 4: Encrypt Backups

Backups are in the server or external drive. Most hackers target the documents in the backups because many people forget to encrypt them while encrypting files on Mac. Therefore, unauthorized persons do not have to target your Mac. They can go after your backups if they are not encrypted and gain access to your files.

So, ensure that you encrypt your Time Machine backups using a strong password that consists of lower and upper case characters.

Tip 5: Encrypt Distributed Files

Files are not always meant to be personal and hence can be distributed. When sending a file to another person, use iMessage since it has end to end encryption. iMessage encryption is trustworthy because even Apple cannot access the file contents. So, only you and the recipient will view the file. It is also a good option because it handles large files.

If you are distributing files to two or more Macs in an office or area occupying the same space, it is advisable to use AirDrop. This is a great solution because you will create a network with each of the recipients, which is secured by a firewall and thus encrypted. You will share the different securely with each Mac despite enabling AirDrop and being within range. AirDrop encryption works best in crowded places too.
