I'm thinking about encrypting my iMac with FileVault. It's a retina with Yosemite, just checking with the experts that there is no risk of any unintended consequences before I do so!

I am a home business user and like the thought if encrypting my business stuff, if it's safe to use!

Any beware ofs to take into account?

Thanks in anticipation

I have long wondered if using Filevault somehow makes it more difficult to recover from any data corruption. Are third party tools harder to use in this situation?

FileVault uses XTS-AES-128 encryption and the key itself is AES-256 encrypted.

It would still take longer than the existence of the universe for all the supercomputers in the world combined to get them.

Huh? This isn't related to my question.

It is safe to use. The biggest thing is storing the FileVault 2 key in a safe place. Without the key, all contents on the drive are essentially lost forever.

... or until quantum computers become mainstream ;-)

Seriously, the reason the FBI etc mandate AES256 and not AES128 is that AES128 will be crackable when quantum computers are realistically available. So perhaps 10 ~ 20 years from now?
