 Today we will show you how to use File Vault 2 on your Mac to encrypt an external drive. File Vault 2 is built into OSX, however it will not encrypt a FAT partition and requires a drive to be formatted as Mac OSX Extended Journaled first with a GUID partition table. We will start this tutorial assuming this has already been completed. It is worth noting though that if you need to use the drive with a Windows computer it will not be readable by Windows. Please see our tutorial on Veracrypt for cross-platform encryption. First we need to right click on the volume we wish to encrypt. Then we select encrypt. Next we will be prompted for a password and a password hint. It is best to use a strong and complex password. Apple has a tool available here to help you create one. However for this example I will use a simple password. Once we have entered the password and the password hint we select encrypt disk. This procedure may take a little while depending on the size of a drive. During this process the drive will disappear and reappear on the computer. I will now speed this part of the tutorial up. As you can see when we next plug the drive in it requires the password we gave above. This concludes our tutorial on encrypting external drive using File Vault 2. Thank you for watching.
