A:

You no longer have a functional OS X system installed. What you are doing cannot properly be done on a computer with an "almost full" drive. You will need to erase the drive then reinstall OS X. If you want an encrypted drive, then choose that option when you re-partition/format the HDD.

 

Install OS X Using Internet Recovery

 

Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

 

Boot to the Internet Recovery HD:

 

Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

 

Partition and Format the hard drive:

 

  1. Select Disk Utility from the main menu and click on the Continue button.
  2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
  3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.

 

Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.

 

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

 

This should restore the version of OS X originally pre-installed on the computer.

    If you just turned on FileVault and hand have a nearly full storage you can expect many more hours...Mac OS X is encrypting your storage and that will take time proportional to the amount of material to encrypt.  That is going to take a really long time.

    Did you read about FileVault first, Use FileVault to encrypt the startup disk on your Mac - Apple Support
