FileVault stuck on "Encryption Paused"

After upgrading my MPB to Yosemite, I elected to turn on FileVault. In the Security & Privacy panel of System Preferences, the status shows "Encryption paused" and the text under the progress bar reads, "Connect power adapter to resume encryption." Trouble is, I am running from the power adapter!


I have rebooted and tried another power adapter. The battery icon in the menu bar correctly changes from battery to power adapter as I connect and disconnect. However, the encryption status never changes. I have left the machine running overnight with no change.

Any ideas?

MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10)

Hello,

I have Sierrra. Enabled filevault and it got stuck.


Solution
:Open Terminal -> type: " sudo fdesetup disable " then paste your password or recovery keyword.


I pasted my recovery keyword and voila it worked again and the process was finished in a few hours :-D


Yay! 🙂


Thank me later 😉

Yes, this may be caused by the UPS bug in El Capitan.


I've had the same issue on a brand new machine, and Disk Utility repair did not help.


I remembered seeing the issue about Time Machine backups not working when a UPS was connected, and sure enough, when I disconnected the UPS and rebooted, Time Machine started working and FileVault continued encrypting.


So, if you are having this problem with El Cap, disconnect your UPS and reboot.

I ran into the same problem today. I got a refurb 13.3 MBP Retina, restored it from a Time Machine backup of the prior laptop, ended up with a paused Filevault encryption that could not be un-paused or turned off. The paused encryption prevented installation of El Capitan.


Many thanks for posting the original message, and to all those who posted their solutions.


I read through everything here and was about to create a USB boot drive, but the last thing I tried worked.


I opened Disk Utility, selected the hard drive and ran Disk Repair on it. The disk repair ran and created many lines of reported activity.


One of those lines said, "The volume / was re-sized to unblock Paused encryption"


When I went back to FileVault in system preferences, the encryption had resumed (Now shows "Optimizing") and gave me a live progress bar with the calculated time remaining.

Fixed:

  1. create a bootable OS X El Capitan USB Drive, (Here's how: https://support.apple.com/en-us/HT201372) Note: you'll need a mac with El Capitan already installed to do this... or if you've got a friend with a working El Capitan system, have them do it.
  2. Boot up you Mac from the Bootable USB Drive (plug in the drive, turn on your mac and hold down "option" as soon as you hear the startup chime) Select the "El Capitan" disk to start from.
  3. When the installer loads, don't install El Capitan, just select "Disk Utility" from the "Utilities" menu, or select it in the options window that loads.
  4. Once Disk Utility loads, select your startup disk in the sidebar and select "unlock" from the file menu. Enter your password when prompted.
  5. Select Disk First Aid and run "Repair Disk" Wait for it to finish. Select Shut down from the apple menu, remove the USB drive, and turn your mac back on. You should now see Encryption resume and complete when looking in System Preferences and Security.
  6. Pour yourself a drink, you've earned it.

Hope you can all make sense of my directions.

Anyone with this issue should try the PRAM reset. You won't lose any data it just fixes this issue up. To do this reset first turn your computer off (shut it down) then when turning it on press command, shift 'R', 'P' while pressing the ON button. After this you should see a black screen with white words on it. I just turned the computer off after all the white words have been said. Then turned it on again and the encryption was working.

PS sorry if this does not work for you it worked for me

Thanks for the suggestion, unfortunately it didn't work for me.


The final lines in the 'details' box of first aid are:

File system check exit code is 0

Updating boot support partitions for the volume as required

Checking for overcommitted space in Logical Volume Group

Shrinking file system

Shrinking Logical Volume

Resizing Core Storage Logical Volume structures

A problem occurred; undoing Logical Volume resize changes.

Operation successful.

Since Apple are the ones who formatted the disk in the first place, it seems they manufactured this unit incorrectly before sending it out, because I've certainly not changed any disk partitions.


I really hate messages like 'A problem occurred' that give no details (especially in a 'details' box): it's like talking to a two year old who's just fed a sandwich to the DVD player.


This only confirms me in never buying Apple products: I only use this Mac because my work writes Mac applications and Apple prohibit virtualised MacOS.
