I just enabled FileVault 2 on my MacBook Pro 15 retina, and realized a small difference from before.
When I close my computer for the day and let it do TimeMachine and all stuff over night it takes slightly longer before I see my Mac in DVTG on my iPhone and iPad.
Before it came instantly, thought it was something wrong but not so.
I just have to wait 5-10 seconds before it shows up and then all syncs perfect.
Good to know, easy to become unpatient and start to fix things that are not broken.
