Filevault for all volumes

disk-utilityencryptionfilevaulthigh sierra

I'm using High Sierra, I have my main Macintosh HD encrypted using Filevault. However in Disk Utility there is an option to create new volumes that share space with container. So finally I have volumes Macintosh HD but also Documents, Music and so on. In Disk Utility I can see now:

  • Macintosh HD – APFS (encrypted)
  • Documents – APFS
  • Music – APFS

As you see there is no information for additional volumes that there are also encrypted.

So the question is – are those volumes encrypted or not (and how can I verify that) and if they are not encrypted how can I encrypt them too using FileVault?

This is screen how it looks like in Disk Utility. As you see this Dokumenty partition is not showed as encrypted but when I choose Macintosh HD there is APFS (encrypted)

This is result of diskutil list:

Best Answer

When you adding APFS container, you should be able to use APFS (Encrypted)

Add APFS volume

I found that after added, it will be shown as 'APFS (Encrypted)' in Disk Utility.app. In diskutil list, no encryption status is metioned.

I didn't find out how to encrypt / unencrypt an existing APFS volume in Disk Utility.app. Maybe some diskutil command will do it.
