FileVault decryption paused, unable to revert

My 2014 MacBook Pro with OS X 10.10.2 became unusable after a crash where the system became unresponsive and I was forced into a hard reboot. As I was using FileVault, the login screen was appearing soon after rebooting, but would freeze at around 40% after putting in my password, after which the spinning wheel would start. The problem even occurred in Safe Mode.
In looking for a solution, it was recommended that I decrypt the drive using the Disk Utility. However, I received an error when attempting to decrypt. I switched to the Terminal to try manually performing the decrypt operation using diskutil. Unfortunately, when trying 'diskutil cs revert UUID', I received the error "Unable to modify a FileVault context". I then tried both encryptVolume and decryptVolume, but they gave me conflicting messages at the disk was decrypted and encrypted already respectively.
Here is a summary of what I see when I run 'diskutil cs list':
Logical Volume Family UUID
Encryption Status: Unlocked
Encryption Type: AES-XTS
Conversion Status: Converting
Conversion Direction: Backward
|
+-> Logical Volume UUID
Conversion Progress: Paused
Revertible: Yes (unlock and decryption required)

Can I disconnect a bitlocker USB drive that is in a state of Decryption (paused) and attach to another machine?

Can I disconnect a bitlocker USB drive that is in a state of Decryption (paused) and attach to another machine?
The background on this question is that I didn't realize at first that I was plugged in to a USB 1.1 hub and it took over 1 hour just to get to 1% decryption. I've paused the decryption but a tad hesitant to disconnect and plug in to another system.

Hi,
How about your problem now? Generally speaking, when you encrypt USB drive using Bitlocker, you can pause encryption if you need to remove the device for some reason. If you don't do so, you could damage or lose files stored on the device.
If you need further assistance on this particular issue or any other Windows related issue, let us know and we will be glad to assist you.

Filevault encryption paused, despite reset of PRAM and using terminal commands

I have been trying to partition my HDD but am unable to because file vault encryption is paused - and has been since October 2014.
I attempted making a new user to see if this would bypass it, but it didn't.
I have reset the PRAM and have repaired the HDD both in recovery and normal, neither work.
I have also used terminal command "sudo fdesetup disable" to attempt turning it off, but that doesn't work either.
Help please??

Has anyone found a solution to fixing the FileVault "encryption paused" error?

I got my Macbook Air in mid January 2015. When I set it up I decided to enable FileVault but after a few minutes the encryption failed and now it will not continue and complete, even when I have my computer on and plugged in. I have seen many different possible solutions, but none that really worked well. Has anyone found a good solution to the issue?

Unable to Revert to Automatic Contact Names

Hello,
I recently renamed a Skype contact and I'm now unable to get Skype to revert back to automatically updating the contact's display name.
Following instructions in another forum post, I removed the custom name by editing the name, leaving it blank and clicking on the tick. This has the effect of updating the contact's name to his or her current name once only. It doesn't restore the default behaviour of automatically updating a contact's display name whenever he or she changes it. How can I get the default behaviour back?

New Macbook Pro FileVault Encrpytion Paused "Connect power adapter to resume encryption"

Does anyone have information on what is causing the FileVault encryption error with OS X Yosemitie? I just purchased a new 15 inch 2.5 GHz (mid-2014) MacBook Pro and during the initial installation / setup I elected to use FileVault to encrypt my 250GB SSD. As the encryption process was completing, it gave me an error stating the encryption was paused and "Connect power adapter to resume encryption."
The MacBook Pro is connected to its power supply. I should note this is my second MBP, I had this same issue with the 1st MBP, which was returned to Apple and replaced with another new MBP. I just don't understand how Apple can release an OS with an option to encrypt the drive if it doesn't work.

So, after 30 minutes with a support person on chat I asked to be escalated. During the time I waited for the sr. tech to come online I decided the best course of action was to erase the disk and re-install Yosemite. The sr. tech came on and said they are very much aware of this issue and the solution is to erase the disk and re-install Yosemite. This was quite easy.
I followed these instructions which matched what the sr. tech provided: OS X Yosemite: Erase and reinstall OS X
Just be sure to erase the correct disk. For me it was the 2nd Macintosh HD in the list.
Also be sure to choose Mac OS Extended (Journaled) as the format, not Mac OS Extended (Journaled, Encrypted).
You'll need to re-install the included apps (Pages, Garage Band, etc.) by going to the App Store and choosing Purchased.
Hope this helps!

Filevault decrypt failure

My usual backup method requires turning off Filevault. However, when trying to do so I get the error: *"an error occurred: an error occurred during decryption (an error occurred during copying). Filevault will be turned on for this home folder and the home folder will still be encrypted"*. I ran disk utility verify disk and repair disk permissions to no avail. I still get the error.
I am running 10.4.10, 2gRAM, 2.33 IC2D MBP.
Help?

Solving File Vault Related Problems
Syd Low offered a helpful tip about recoving damaged Mac OS X FileVault data:
Apple's knowledge base article on this problem - How to verify or repair a home directory image - didn't work for me. When you click repair at step 12 Disk Utilty will not be able to repair the volume because of permission problems. Here's what I did:
I added write permission using the command line. Open the Terminal (Utilities folder) and at the prompt enter the following commands pressing return at the end of each:
prompt > cd /Users/accountname
prompt > sudo chmod g+w accountname.sparseimage
You will be asked to enter your admin password. It will not be echoed.
prompt > sudo chmod g+w /Users/accountname
Now you can run Disk Utility to repair the image successfully. Remember to change the permissions back afterwards:
prompt > sudo chmod g-w accountname.sparseimage
prompt > sudo chmod g-w /Users/accountname
Also read the following in the event the above doesn't help:
FileVault-protected Home shows less capacity than what's available on the hard disk.

FileVault Decryption stuck at 100% in Terminal

I'm having a problem with decrypting in recovery mode using command line. I have setup an institutional recovery and have successfully encrypted the hard drive on my Mac. I am testing unlocking and decrypting the hard drive with the institutional recovery key I setup which works, up until the final decyrption. I reboot into recovery (command+R), open terminal and I can successfully unlock the encrypted hard drive with the recovery key giving me access to its contents. I then decrypt the hard drive with the recovery key using the following command: diskutil corestorage revert <UUID> -recoveryKeychain /path/to/FileVaultMaster.keychain
The decryption successfully starts and I use diskutil corestorage list to show the status of the decryption. The progress in the Logical Volume section continues going up until it reaches 100% and it appears to stay stuck there at 100%, even after leaving it over night. In the Logical Volume Family section, the conversion status still shows "Converting" and the conversion direction still shows "backward" even though under Logical Volume, it shows "Conversion progress: 100%" Why does the conversions status never change to complete?
Should I have used the decryptVolume command instead, like so: diskutil corestorage decryptVolume <UUID> -recoveryKeychain /path/to/FileVaultMaster.keychain
What is the difference between the revert command and decryptVolume command?
I'm running 10.9.4 Mavericks and have reproduced the problem on both a Macbook Pro and an iMac.

Stuck on FileVault Decrypt

I have turned FileVault off....
It is stuck on a screen that says
"Decrypting xxxx's Home Folder
Time remaining: About 1 hour"
- The blue progress bar is not moving
- The time is not going down
- There is a pin wheel (not beach ball) spinning around just infront of the FileVault Dialogue
Touching the trackpad does not move anything.
What do I do?
The laptop appeared to have gone to sleep before it finished.

Follow up to my previous post. I just did a hard reset by holding down the power button and it started up fine. I then turned filevault back on, and it seemed to encrypt OK until it got to the part where it deletes the old user directory and then it hung with no progress on the progress bar. After many hours it crashed with the death screen requiring a hard reset. It started up OK with the Apple crash reporter activated.
I hope everything is OK. Any thoughts?

Filevault decryption hangs

Hello,
I'm running 10.9.3 on a late 2011 macbook pro. I had file vault turned on my system. I needed to turn off file vault. So I hit the "turn off filevault" button. It has been 5 days and its still showing "decrypting... estimating time remaining..." The disk is a 750gb disk with 262gb used. I ran the diskutil cli and it tells me the the disk is backward converting (as pasted below). The drive sounds busy when i put the laptop up to my ear. Does anyone know how to check the status of the decryption beyond "converting?"

FileVault decryption problem fixed

I had posted on April 30 that I could not decrypt my FileVault home folder. TechToolPro 4 and Disk Utility both reported problems, but offered no solutions. Today I got a DiskWarrior CD, and it immediately found the problems and fixed them. Easy as pie. Wanted to post this in case others have similar issues with FileVault.

Well done, and thanks for the post back.

Unable to revert back to an old BIOS?

I updated my Neo Platinum's BIOS from 1.1 to 1.3 in attempts to resolve the temperature issue, but it only resulted in BSOD's when loading Windows XP. I reverted back to 1.1, and everything was fine again. I then tried the beta 1.45 BIOS, and got BSOD's again. When I tried to revert back to 1.1, the flash utility gave me a message that the chip was write protected. As far as I know, there is no write protection .
I've tried using different versions of the flash utility, messing around with hardware, and reinstalling Windows. Nothing works. What the deuce can I do to resolve this issue?! The BSOD I get is a generic one that doesn't specify anything. The only conflict I can see is the A-Data PC4200, although some say that they work wel with this board. How can I get around this?

Bah!! I finally managed to get it. All I had to do was add the /f command to the end of the prompt. To whomever wrote the installation instructions, this was the most complicated BIOS flash I have ever gone through. I shall forever stick to my floppy diskettes and DOS. LiveUpdate will not become a part of my system ever again.
