I enabled FileVault to encrypt my hard drive a few days ago. The encryption process is still not finished and the estimated time keeps changing. It's been anything between "4 days" and "300 days". The encryption process running in the background makes my MacBook Air (from mid-2011, OS X Yosemite) heat up very quickly.
I'd quite like to stop the process, or at least know how much longer it will take. How do I do that?
I'm also wondering if, in order to complete the process, I have to keep the computer turned on. Does the computer sleep mode pause the encryption?
I made a back-up of my computer's hard drive before I started the encryption process.
