    I updated my Macbook Air (Mid 2011) to Yosemite yesterday and enabled FileVault during the installation. It's been more than 24 hours and it's still going. The estimated time remaining seems to vary wildly going from 29 days to 128 days to 333 days to 90 days the last time I checked it. I did the Terminal command to check the progess. Here are the results. Where do I go from here?

    It shows that (for whatever reason) the conversion failed. I would delete the drive in disk utility and install Yosemite again. A few other people on the forum have reported that FileVault appears to get stuck during the process and never seems to finish.

    You can try enabling FileVault in preferences, but I doubt that will work if the system still thinks FileVault is working. It should have been done a long time ago on such a small drive.

    Do I delete the drive in Disk Utility and then reboot? Or should I erase? How do I get back to the Yosemite Installation? Do I then have to restore everything to my drive using Time Machine?

    Thanks for your help!

    If you have a Time Machine backup that was made before encrypting your drive or installing Yosemite, you can boot your computer via the Command +R option and then pick the restore from Time Machine backup option. That would be the simple way to go. If that is the case for you, make sure to download Yosemite again. Once it finishes downloading to the Applications folder, you can double click the file to start your upgrade installation, or you can follow the steps outline below, to do a clean install of Yosemite.

    *** Upgrading to Yosemite is a fairly simple process. The following is for anyone that wishes to do a clean install of Yosemite. If you want to upgrade over Mavericks, download the Yosemite file from the MAS. It downloads to the Applications folder. When it is finished, double click it and it will start the upgrade process.

    1) Backup your computer using Time Machine, Clear Copy Cloner, or SuperDuper

    2) Download Yosemite from the MAS

    3) The file downloads to your applications folder. Once it finishes, it will want to start the install process. Exit out of the install

    4) Make a USB Yosemite installer. You need a 8 GB USB drive and about 20 minutes. The directions are very easy and can be found here.

    5) Once you have the USB installer made, restart your computer and hold down the Command and R button at the same time. Once you see the progress bar start, you can release.

    6) Your system will boot into Disk Utility. You want to You want to focus on the bottom option on the screen, because you want to erase your HDD. Erase your HDD and exit out of Disk Utility.

    7) Reboot your machine while holding down the option button. The screen that follows will show your Macintosh HD and your newly created Yosemite USB installer options. Click on the Yosemite option. This will start the installation process.

    8) During the Yosemite installation, the option to enable FileVault is already checked by default. If you don't want to use FileVault, make sure you uncheck that box.

    ** You don't have to create a USB installer if you want to upgrade over Mavericks. You can simply download the Yosemite installer as noted before, and then double click it in the Applications folder. That will start the upgrade process. If something goes awry during the install, you will have to download the Yosemite file again, as it gets deleted during install. The method I outlined if for anyone that wishes to do a clean install of the OS.

    No problems with Yosemite until enabling FV2, then it hung at the "Optimising" state with 40% complete....CMD+R reboot shows nothing can be done with the SSD although it verifies and repairs as "ok".

    Have shrunk the partition on my 1TB media drive and created another 100GB partition, now restoring the SSD image to it from TM.....will then boot from that and then consider what to do with the SSD, suspect it will need pulling and formatting on a Win machine...

    Done, about 2hrs to recover as I had an external dock to hand, had to delete the core storage group and volume, then partition with DU, then restore with CCC....have left a backup bootable volume on the HDD just in case...
