How to stop FileVault full disk encryption in progress.Please advise asap please Thank you

I have the same problem and found these solutions online however after going through the steps I encountered a new problem due to my partition on the disk. So to summarise what I found out, this problem is caused by the FileVault that has detected a defect in the disk whilst encrypting it and it is now caught in a loop attempting to encrypt that section. Fixing the disk should jump the FileVAult back on track and make it able to finish encryption. so it can then be switched off.

1. Reboot your Mac and hold Command-R at the startup sound and wait until the machine moves into Recovery Mode.

2. Open Disk Utility from the menu that appears on screen.

3. Select your boot drive from the list, if you have no partitions or other disks mounted it should be obvious it is a single disk there , perhaps called Macintosh HD.

4. Unlock it if it is locked then hold Command button down while you select it again from the list on the left side.

5. Several options appear available to click now, and hopefully that main disk will show the First AID menu, in blue when selected at the top of the window and several actions for it in light grey at the bottom of the window. You can either verify for faults in the disk that are causing the FileVault to loop and never finish encrypting or to immediately repair whatever is wrong. Either way, the disk needs fixing which is what people seem to suggest is the case for the long encrypting estimates. Mine alternates between 35 and 50 days to go!

6. After you have repaired the disk, restart the disk and log in as you would normally and check again the the Security&Privacy menu from System Preferences that the FileVault encryption has picked up on the encryption and is no longer showing crazy estimates. Some people seem to manage to fix it that way.

IF STILL NOT FIXED,

Other users have suggested going back into the recovery mode again and choosing at step 2 to re-install the OS X completely, this time not allowing the FileVault to be turned on at all when prompted.

I have attempted that and got almost up to the end with the OS X re-installation when I got the following message : "The Core Storage operation is not allowed on a sparse logical volume group. Quit the installer to restart your computer and try again"

Needless to say I have tried it several times and each time in the last minutes of the re-installing I got the same message, so I am stuck at another stage now.

Hopefully though, one of these previous steps will be enough to fix your disk, if you find a solution please post it.

Thanks,

Same here.

The macOS re-installation DOESN'T EVEN COMMENCEbecause of the ongoing/never-ending Filevault encryption (screenshot attached for reference).

It's a Catch-22 which, I'M SURPRISED, why Apple hasn't corrected all these years!

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 😉

you must cut the WiFi because your macbook is always synchronizing with iPhone (iMessages) or internet and then writing to the disk never stops... thus encryption FileVault never stops.

If you stop wifi and stop writting on the disk (creating files or copying files on it) then FileVault will finnish (the less data you have on the disk/ssd, the faster FileVault will occur).

Same problem here. Many users have this problem. Apple pls respond.

Hey !

I have the same probleme, but I'm a bit scary to do that... Has this operation deleted your data ?

Thanks in advance !

Nope, doesn't work for some reason. I get no options to unlock when I hold command and click. Annoying, guess I'll have to wait it out.

still not working? might have a fix for you if you still can’t unlock your disk.

I am having exactly the same issue.

Thank you Macalexa 🙂

But when I tried sudo fdesetup disable it came out command not found. Any solutions for this issue my prob is exactly like pic above
