Catalina Won't Install BC of FileVault

[ekkojelly7]

When I try to update to Catalina and choose a disk to land it I get this:



So when I try to turn FileVault off it takes forever and finally gives up and I get a dark screen with the arrow cursor and eventually I get a box that says a file won't allow file vault to be turned off. Tried this about 3 times.

I get this box when I open Security & Privacy:

Are you using ny of the Songs software which supports some of the features for their speakers? I did a quick search and saw several references going back as far as at least High Sierra that this software generates that error though there could be others. The solution seems to be to completely remove the offending piece of software.

BTW you do have more than enough space for Filevault to decrypt and expand yer ole right? I'm pretty sure that has to be done before FileVault can be turned off.

Yes, I do have space. I have tried to turn it off before and was unable to for that reason but would always got a dialogue box that said so. The install box above shows "715" GB available. I would think that's enough.

...no Songs software.

Why not create a macOS bootable USB installer, How to create a bootable installer for macOS - Apple Support As long as you have a current good backup of all of your important data/files, that will be all you need. Then you can boot from the USB and erase/wipe the internal drive prior to installing Catalina.

If you use Time Machine, there will be the option to import everything from your old Mac.

Just noticed there is an error in my previous post. It should say Sonus software not songs.

Probably a typo on my part but I'm blaming it on autocorrect.

How long can the de-encryption take? A few hours, days?

Depending on the size of the drive, and the percentage of data on it, yes it could take days. Especially if you're using the Mac as well.

As above.....

All good reasons why we recommend not using FileVault.

+1!!! And avoid using the Old or New FileVault versions!!! Even if Apple Does suggest doing so!!!

After about 2 hrs of “decryption” I got this message:



I am seriously annoyed now.

So if I have 1.02 TB of memory and 715GB available wouldn’t that be enough to copy and decrypt with Legacy FileVault?

Yes, unless you have another user account on the computer. Then you may need to unlock it before de-decrypting can work? That was why I mentioned this, #5.

 

[ekkojelly7]

If I'm the administrator wouldn't any account automatically be unlocked?

No, when you put in your user Name and Password in, that goes you limited permission to read and or write to their account.

I was able to turn off FileVault yet I still get the "You may not install this volume because it has Legacy FileVault users" and yes I restarted.

Look at the user accounts on your machine. When you open one of those folders there should be several folders inside.(Documents, Music, etc). If you don't see that this is probably the user with legacy FileVault enabled. The solutions that I've seen all involve moving the encrypted file then deleting the affected user account or reformatting the drive.

Of course it goes without saying that anything along those lines should only be done once important data has been backed up.

That could be quite a bummer, especially if the critical file is the one that's corrupted and not accessible, hence the warning here and the advice not to use or enableFileVault in the first place makes very good sense.


Anyway, a bit of a quandary and mess at this point.

My be at the point of having to wipe the drive completely to gain control. Ugly.

Wonder if it is possible to delete the user with the Filevault on? Worth a try, I suppose.
