Question: Legacy FireVault

I tried to update from OS Sierra 10.12.6 to OS High Sierra and got a message i cannot update because of Legacy FireVault. Why not?

iMac (21.5-inch Mid 2011)

Posted on

Question marked as Apple Recommended

It may not be compatible with High Sierra since for some computers, the file system is changed. Decrepit the drive and try the update again.

File Vault is already turned off !?

my original message when trying to update is (I think the same as original question on this thread)

You may not install to this volume because it has legacy filevault users.


I have MacHD 122.77 GB available.

Hi, I have exactly the same problem. Drive not encrypted, message exactly the same "You may not install to this volume because it has Legacy FileVault users".

Tried Ctrl+Click, no decrypt option.

Any advice would be very helpful... what about just doing a backup and reformatting?

This links to a doc indicating "Sonos" app could be at fault and I should remove it. I have no such app

If the Sonos app could cause this problem, is it possible some other 3rd party software could cause the same problem?

You should review all your 3rd party apps to see if there is something else you have installed causing the Legacy FileVault report
