Bad things happen and sometimes those bad things cause your FileVault 2-encrypted Mac to be unbootable. In the event that you find yourself in this place, or youre about to be, heres how you can unlock or decrypt your FileVault 2-encrypted drive using Disk Utility and the password of an account thats authorized to log in at the FileVault 2 pre-boot login screen. Update June 11, 2013: As of Mac OS X 10.8.4, you will need to unlock the encrypted volume first, then you will be able to decrypt it. See this post for details. 1.

Boot your Mac and hold down -R (Command R) to boot from the Macs Recovery HD partition. Note: You can also boot from a 10.7 installer drive , boot to Target Disk Mode and connect it via Firewire or Thunderbolt to another Mac, or use some other 10.7-booting drive. As long as you have 10.7s Disk Utility, this should work. 2.

Open Disk Utility. 3. Select your locked hard drive. 4.

Under the File menu, select Unlock Drive Name or Turn Off Encryption , based on what you want to do. 5. When prompted for a password, you can enter the password of any authorized account on the drive. 6. If you unlock the drive, you should then be able to use Disk Utilitys repair tools to hopefully fix the problem thats preventing your Mac from booting.

7. If you turn off the encryption, the encrypted drive will decrypt. Once its finished decrypting, you should be able to access your data again using normal recovery methods (booting from another 10.6 or 10.7 boot drive, utility drive, etc.)In my case it does not work. The File menu does not give a chance neither to unlock nor off encryption. I wonder what version of DU rtrouton used to having unlock and encryption off choices in DU File menu?

My MacBook Pro went in to reboot and when it starts up I can choose between My usersname or Guest, but when I click on My username it just keep loading a bit and then show the Mac Stop sign. I can log in as guest and log in trough Coomand+R, but when I try doing a Reinstall Mac OS X it show Recovery HD but This disk is lockedI use FireVault, can this also be an issue ? I have the same question: what if this doesnt work? Ive booted from a Mountain Lion install flash drive and tried to partition the Macintosh HD, but this is not possible. The Verify Disk and Repair Disk runs with no error, but on the Partition tab all content is geyed out.

If I choose Reinstall OS X the only installable medium shown is the flash drive. The Mac. HD does not show up. What to do? If your Macs boot drive is encrypted with FileVault 2, you will need to decrypt it before installing (or reinstalling) OS X. You also need to decrypt it before Disk Utility will be able to repartition your drive.

Thanks for your answer. I have two possibilities: Hold the option button pressed and load the Flash Drive, then the Hard Drive is still encrypted. The decrypt and other options in the Disk Utility are greyed out as well as the partitioning tab. The other option is to boot into the hard drive.

I enter the pass phrase and the mac tries to boot for a while, then shows a question mark and doesnt do anything further. I am really annoyed at this point since I have to finish my paper till next week Any suggestions? Youll be my hero.

You, Sir, saved my weekend. Thank you a thousand times. Couldnt decrypt the FS anymore, so I totally erased it with diskutil corestorage delete. Thats totally ok for me, since my data is on an other drive. Again, thank you.

Another option is to boot from your installation USB drive, then select the Apple and Startup Disk. Unlock your HDD from there, quit the Startup Disk utility and youll be back in the main installer. With Disk Utility you can then fully wipe your disk. Thank you for this, which I hope is about to get me out of a major hole. Two questions:1. How long does the decryption usually take?

It still says converting but theres a disconcerting lack of disk activity. 2. After doing this will I automatically get a normal Mac login instead of a FileVault login screen?

Many ThanksBenBen,Itll take as long to decrypt as it did to encrypt. If the drive was having problems, it may take longer. Once you begin decryption and reboot, you should be back to using the Macs regular login screen instead of the FileVault 2 pre-boot login screen. For all who are having problems of not having Unlock menu. Select the Volume than the HDD and then check the file menu i.e when you see on the tree view the first (top) most is your HDD then the second item below would be your volume. So, if your name of your HDD/Volume is example_mac.

example_mac < HDD__example_mac < VolumeHope this helps. Hello. Ive faced a serious problem which I cant solve for several weeks already. The last hope is your help. My father has an external usb drive with his own data on it.

He used Mountain Lion before but some time ago he upgraded his OS X to Mavericks. When he used his external drive in Mountain Lion system it didnt ask for password when the drive was mounted but after upgrade it began to ask for password to decrypt the drive. He tried every password he usually used for systems administrator account or everywhere else but there was no luck. Password hint says last name date (exactly date, not data) and he insists that he didnt enter any encryption password or any security questions all the more so. So more likely I cant have encryption password to be recovered (and recovery key too) but I need to recover the data on the drive.

What I can do with this case? Ive found software named Passware Kit Forensic that can decrypt FireVault2 drives but it needs physical memory image which I think is useless now from upgraded to OS X Mavericks system. I cant believe Im the first on the planet who faced this problem and Im sure there is a solution for it. Thanks beforeIt may be that (1) the external drive was encrypted all along, but it auto-mounted because the password was stored in the Apple Keychain and (2) the upgrade to Mavericks reset or lost the keychain. If you have a pre-Mavericks backup, maybe someone here can tell you where to find the keychain.

Mine allows me to unlock but does not give me the option to Turn Off Encryption because it is greyed out. Ive been trying to resolve this for a while but still no success. Ive tried everything Ive come across on the net that seems to be resolving everyone elses problem but nothing has helped. My MBP is only about 2 weeks old and only has about 80 GB of music and Pictures stored on it. Any help is greatly appreciated I did a mistake, and I need help I installe maverick in a ssd during the installation it asked me to activate firevault and I did so when it was over my pad click was not working and so I intried to reinstall and I did a huge mistake I just erased the partition and tried to re install but on my disk utilities I can see the drive but it says is locked I can access an option so if I can get some help I would appreciatedHELLO PPL,I need urgent help as my Mac (on El Captain) has stuck on the FilVault thing which is encrypting the disk for past 2weeks.

Checked with Apple advisor who suggested to use Recovery mode to Unlock the disk, I did that by clicking UNLOCK button but the issue is I really dont know if the process is done or not (HOW LONG DOES THIS SHOULD TAKE)Please help what should I donto get out of the perpetual encryption in the FileVault. Thank you so much in advance. AlarkGood afternoon,I was wondering; if I were to encrypt my files on a mac book that I do not have administrator privileges for, can those files than be decrypted once I hand my laptop back??
