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:

  • This sounds rather strange. I've never seen this. Can you provide a screenshot or if rep is too low run a diskutil list in the terminal and copy the output and update your question. The only way this could be true is if you have external Volumes either Partitions or USB,network drives, etc.

  • @Jahhein Thanks for interest, I've added screen and command output into question Feb 26, 2018 at 18:11
  • That is very strange. The screenshot of the answer below is how a single partition APSF disk should be. If you do a 'diskutil coreStorage list' it will show all encrypted volumes that are connected and they are unlocked or not. However in the end, I think you have another issue with this other than encrypted or not.

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.


Is the Documents and Music a separate partition or the same with the System? Can you post a picture of the disk utility? As I checked mine, all files are encrypted in one drive. You may need to encrypt the separate partition if you opt not to encrypt them before. But if you turn on the Firevault in the beginning then all files should have already been encrypted.

  • It seems that you have different volumes each mounted at different location. I think only the volume "Macintosh HD" is encrypted and everything else is not. support.apple.com/en-us/HT204837 Upon checking information online, Firevault only encrypts startup disk (in your case, "Macintosh HD.") Should you want to encrypt other disks, merge them into one disk or encrypt them separately using password.

Check the article I found on the Apple discussions website regarding FV and APFS. I think it will clarify one or two things. The last post by 'etresoft' on the second page is the most interesting one. APFS vs. FileVault
