i read this on a recent post " Avenged110 said: ↑ Mavericks (and Safari) should get maybe one or two more security updates before 10.12 hits in October. After that my plan is just to keep FileVault enabled and both firewalls at their highest levels. " I have never bothered with file vault - it just seemed like another way for corruption to creep in. Also i had the understandinging that its main use was to prevent someone being able to remove a HD from one computer and loading it into another one ( to be able to read it. ) The 3 or 4 critical files that i have on my mac are enclosed in encrypted dmg files. Am i missing another reason to turn on file vault ? Thoughts please.
