FileVault stuck on "Encryption Paused"

I have found why the password does not work.

When booting from the rescue mode and when I launch Disk Utility, the keyboard layout is in French. But when the popup to fill the password is open, the keyboard layout switches to English, don't ask me why...

None of the suggested solutions works for me - Can't turn off encryption from disk util in revovery mode as "turn of encryption" is greyed out even after unlocking the drive by entering password. Same with or without AC connected

The "sudo fdesetup disable" command does nothing.

sudo

I'm really stuck here and really in trouble as I need the perfoamnace to get my audio work done..

After my decryption got stuck, I finally just did and erase/format and reinstalled OS X Yosemite. Then I did a restore from my most current time capsule backup. I upgraded my memory to 8gb. Now Yosemite is flying. I wasted way too much time with the fixes. I should have just wiped/installed/restored files way earlier.

***** ONLY DO THIS IF YOU HAVE ALL FILES BACKED UP

There is nothing to do too, Disable Encryption is greyed, nothing works but this method :

- Boot from the rescue partition

- Erase the System partition : it was not possible to format it... an other bug in the Disk Utility.

- Create an empty partition

- Install Yosemite from scratch

- Disable FileVault of course !

- And then restore files from the timecapsule

I was able to solve my issue after 15 days of trying. here are the steps that finally worked

0 - make sure you are connected to a power source

1 - need to create some extra empty space on your drive. I have a 1TB SSD that was almost full. I removed around 300GB of data at first

2 - restart your computer

3 - reset PRAM (Command + Option + P + R )

4 - as soon as it reboots hold down Command + R

5 - select Macintosh HD or whatever your HDD is called

6 - repair permission first

7 - then repair disk

8 - then repair the main disk / parent HDD

9 - then restart

FileVault started working for me right after that and it finished after about 15 hours. I turned it off after it complete the encryption and it took around 8 hours to turn it off. now everything is back to normal

Quite Strange .... After having gived up walting for a fix from Apple, my filevault suddenly starts again. After having been stuck for days it reports that it is encrypting and will be done in 10 minutes. BUT After that was completed it now reports "optimizing" still not allowing me to turn off filevault. "Great" thing is that my system reports that it will be optimizing for 12 days. Whenever I do ANYTHING on the computer, that number goes up a LOT. My disk is 1 TB SSD with 380 GB free

I have totally reinstall Yosemite :

0. Backup your system in a Time Machine backup

1. Boot from the recovery partition

2. Go to Disk Utility

3. Erase your Hard Drive

4. Format your Hard Drive

5. Quit Disk Utility

6. Install Yosemite without restoring anything

7. At the end of the installation, installation program ask you whether you want or not FileFault : deactivate it !

8. At the end of the installation, create a user toto or tata

9. Run /Applications/Utilities/Migration Assistant

10. Restore full backup with system preferences, applications, user files, etc... from your Time Machine backup

I just noticed one thing that may come handy form one: having gone through all these steps I saw the encryption resuming at first but then stopping again as described by so may. Then I wanted to make an TimeMachine backup for the inevitable new installation of Yosemite and for that I switched off my WLAN connection to not disturb the backup to a connected USB drive. But I digress, because this is the key thing: after i switched off the Wifi connection on the Mac, encryption of FileVault resumed again (switching it on again made it stop, and off again made it work again...). This may not help everyone, but it could be worth a try for some to go through the steps suggested by rash and then restarting with all wifi connections switched off.

Hi,

Potsky's comment quoted below works...

HOWEVER, it is important to note that when selecting the erase/format type you should select Journaled Only. It defaults to Journaled,Encrypted. If you do this when you install Yosemite it will be the same error. Journaled only resolves the problem.

This even works for just a plain Yosemite re-install without time machine.

Your guide and Potsky's guide worked for me!

The only issues I had that I later learned were:

When you boot your Mac, hold Command+R to go to recovery mode.

You have to ERASE your Macintosh HD in Disk Utility first, to install a clean version of Yosemite.

The whole process, from start to finish, took about 27mins. However, I didn't have to backup my data, nor restore, thus the shorter time.

Anyone suffering the problem with FileVault paused due to it thinking there is no power supply connected should try Frederico's solution. I have a brand-new 15 MBP which I set up yesterday. I hovered on the option to leave FileVault in the default 'ON' state and in the end decided to trust it. So irritated to find it couldn't cope with being paused. Anyway, thank you Frederico, your solution seems to be working a treat!

You dont need to reinstall Yosemite to stop the encryption.

Just follow these steps...

(Have laptop powered through mains)

Reset pram with option+cmd+p+r

Booting with cmd+r for utility disc

Select the partition encrypted>click file and unlock>repair the partition disk>repair permission on partition>repair macintosh hd

Then restart, encryption should continue (time to complete varies)

Then follow this link if that does not work....

Worked for me after a week of trying everything listed previously.

MacBook Pro - late 2010

Excellent summary. Thanks. I followed the steps but it is still not perfect. My problem is not as bad as others. I still see "Connect power adapter to resume encryption." (The power adapter is connected.). But I also see "FileVault is turned on for the disk 'Macintosh HD'." I am also not having performance problems the way others are. MY QUESTION: Should I just forget about it for now since performance seems to be OK...and since it says FileVault is turned on? Or is there something else I should do? ("Turn off FileVault" is gray so I can't do that.)

...Using brand new MacBook Pro and I'm now setting it up for the first time.

+1

Same problem here. New Mac Book Pro Retina, selected File Vault in initial configuration of system. File Vault is on pause with message to attach the mac book to power source, while it is... Already wasted half a day on this topic and different approaches also from this thread. Nothing would help.

Called Apple Care Support (again 1-2 hours in hotline...):

- Explained the situation to support person A, no fix.

- Explained the situation to support person B, no fix, but I sent some logs to Apple with their support logging tool, which is forwarded to development according to support person B. Now I have to wait about 2 business days for news. Will report in case something helpful will come up.

Um, yeah...

Gerjant-

If you have a time machine backup, quit wasting all that time.

Delete and reinstall yosemite without file vault and without restoring anything.

Then restart w/ ⌘+R and select restore from Time Machine.

It's very little work...mostly sitting there and worrying about losing data ...you won't.

I went through all the pain you did until I gave up and admitted I needed to wipe the drive...

Good luck

Tom
